Introduction

This Special Instruction is intended as a general reference regarding the configurations of the transmission, engine and implement Electronic Control Module (ECM) on mid-size wheel loaders.

Note: The 938H includes the IT38H and the 962H Includes IT62H unless noted.

Note: The transmission, the engine and implement configurations are programmed from the factory per the machine shipping order. Changes or adjustments may need to be chosen due to the operator and customer preferences, the addition of an attachment, reinstallation of software or replacement of the ECM. Electronic Technician (ET) and in some cases the 4C-8195 Control Service Tool should be used to configure and or adjust the configurations. When changing some of the configurations it maybe necessary to recalibrate the system.

Machine Speed Limit (938H and 980H)

The machine speed limit can be adjusted for the desired maximum speed for the operation. This feature is available on the 938H and 980H. The speed limit can be adjusted in increments. The increments are based on top speed for each gear with a minimum of 6 mph and a maximum setting of 28 mph. If the ground speed limiter is installed on the machine, the machine speed limit will not be adjustable above 20 mph. Once the ground speed limiter is installed, a password will be required to change the machine speed limit on the 938H.

Ground Speed Limiter Installation Status (938H to 980H)

The installation status of the ground speed limiter limits the 950H through 972H machine ground speed to 20 km/h (12 mph). The machine ground speed limit on the 938H and the 980H is determined by setting the machine speed limit. The factory password is required to install or to uninstall the ground speed limiter on the 950H through the 972H.

Transmission Maximum Forward Gear (938H to 980H)

The transmission maximum forward gear sets the maximum gear that the machine will shift to in the forward direction.

Transmission Maximum Reverse Gear (938H to 980H)

The transmission maximum reverse gear sets the maximum gear to which the machine will shift to in the reverse direction.

Forward to Reverse Desired Gear (938H to 980H)

The forward gear to reverse gear sets the gear to which the machine shifts when changing direction from forward to reverse.

Reverse to Forward Desired Gear (938H to 980H)

The reverse to forward gear sets the gear to which the machine shifts when changing direction from reverse to forward.

Speed Shift Control Throttle Shift Enabled Status (938H)

The speed shift control throttle shift lowers the engine speed briefly in order to reduce the loads on the drive train during a directional shift and or a speed shift. This results in a smoother shift. Select disabled or enabled for the 938H.

Control Throttle Shift (CTS) Enable (950H to 980H)

The Control Throttle Shift (CTS) lowers the engine speed briefly in order to reduce the loads on the drive train during a directional shift, resulting in a smoother shift. Select Disabled or Enabled for the 950H to the 980H CTS configuration.

Tire Rolling Radius (938H to 980H)

The tire rolling radius setting improves the speedometer accuracy. The tire rolling radius is defined as the distance from the center of the wheel hub to the ground. Enter the tire rolling radius for the tires installed on the machine.

Ride Control Configuration (950H to 980H) or Ride Control System Installation Status (938H)

The ride control system acts as a shock absorber by dampening forces from the bucket when traveling over rough terrain, helping to stabilize the entire machine.

For the 938H ride control system installation status select "Installed" or "Not Installed". For the 950H through 980H ride control configuration select "Improved (2-valve) "or "Not Installed".

Ride Control Forward Activation Speed (938H to 980H)

The ride control forward activation speed sets the forward speed at which the ride control will activate. The activation speed for the ride control can be adjusted in 0.16 km/h (0.1 mph) increments. The forward activation speed may be adjusted between 1.6 km/h (1 mph) to 32 km/h (19.9 mph) for the 938H to the 980H.

Ride Control Reverse Activation Speed (938H to 980H)

The ride control reverse activation speed sets the reverse speed at which the ride control will activate. The activation speed for the ride control can be adjusted in 0.16 km/h (0.1 mph) increments. The reverse activation speed may be adjusted between 1.6 km/h (1 mph) to 32 km/h (19.9 mph) for the 938H to the 980H.

Ride Control Pressure Equalization Time (950H to 980H)

The ride control pressure equalization time is the transition time between "OFF" and "ON" for the ride control. This transition is the time that is required to equalize the pressure between the ride control accumulator and the lift cylinders. The factory setting of the pressure equalization time for the 980H is 1 second and for the 950H to 972H is 3 seconds. For the 950H to 980H the pressure equalization time is adjustable from 0 seconds to 20 seconds in 1 second increments. This setting is not adjustable on the 938H machine.

Secondary Steering (938H to 980H)

The secondary steering system provides temporary steering control when the primary steering system does not operate properly or the engine is not running.

Select "Installed " if the machine is equipped with the secondary steering attachment.

Command Control Steering (CCS) Installation Status (950H to 980H)

Command control steering is a load-sensing system that has a 70 degrees steering wheel angle, left or right, from center, which provides full machine articulation. Command control steering is standard on all 980H machines. Check the product configuration for individual 950H to 972H machines to determine if the machine is equipped with command control steering. Command control steering is not available for the 938H.

Select "Installed" if the machine is equipped with command control steering.

Integrated Braking System (IBS) Manual Mode Enable Status (938H to 980H)

The Integrated Braking System (IBS) enables the operator to downshift and neutralize the transmission by depressing the left brake pedal.

The Integrated Braking System (IBS) is always enabled in the autoshift modes. The ability to enable or disable IBS applies only in the manual shifting mode and it only disables the downshift logic, the neutralizer is still present. To disable IBS in the manual mode the Integrated Braking System (IBS) manual mode enable status should be set to "Disable". When IBS "Manual Disable" is configured and the transmission control is in the "Manual" position the transmission will not downshift when the left brake pedal is depressed.

Neutralizer Settings (938H)

The transmission will be neutralized when the left brake pedal is depressed to the transmission neutralization setpoint. For the 938H there are three neutralizer settings which allow configuration of the neutralizer portion of the IBS for application requirements in level, moderate and aggressive slope operation. Adjust the neutralizer settings according to the machine site conditions.

Level Operation Neutralization Offset Setpoint

The level neutralizer setting should be adjusted and used for situations where the machine is operating on level ground. The level setting cannot be set below the brake point (0.0%) or above or equal to the moderate slope setting.

Moderate Slope Operation Neutralization Offset Setpoint

The moderate neutralizer setting should be adjusted and used for situations where the machine is operating on a moderate incline. The moderate slope setting cannot be set below or equal to the level setting. The moderate slope setting cannot be above or equal to the aggressive slope setting.

Aggressive Slope Operation Neutralization Offset Setpoint

The aggressive neutralizer setting should be adjusted and used for situations where the machine is operating on an steep incline, for the site. The aggressive slope setting cannot be set below or equal to the moderate slope setting or above the maximum allowed setting.

Brake Measurement (950H to 972H)

The Brake Measurement is used to help calculate the amount of wear for a given brake disc. Each individual service brake uses an indicator pin to help determine the amount of wear on an existing service brake disc. An indicator pin is located on each side of the front and rear axle center housings. The brake measurement information is recorded in the transmission Electronic Control Module (ECM).

Record a new baseline value whenever a new brake disc is installed. After entering the new brake measurement values enter the SMU when these new brakes were installed in the break measurement hour meter reading. Record a new baseline value ONLY for the respective brakes that received a new brake disc. The baseline value should not be updated for brakes that did not receive a new brake disc. The following information is recorded:

• Right front brake measurement.

• Left front brake measurement

• Left rear brake measurement.

• Right rear brake measurement.

• Brake measurement hour meter reading.

Transmission Type (980H)

For the 980H the machine may be built with a standard or a heavy duty transmission. The heavy duty transmission is also referred to as an extreme service transmission in some documentation. For the transmission type select "Heavy Duty" if the machine is built with the heavy duty transmission. Check the product configuration for individual 980H machines to determine if the heavy duty transmission is installed.

Advanced Machine Security System Installation Status (938H to 980H)

The Machine Security System (MSS) protects from vandalism and theft by preventing unauthorized personnel from starting the machine. Machines start only after a unique Machine Security System (MSS) key is inserted into the ignition. MSS keys can be programed to start the machines only certain days or hours. If the machine is equipped with the MSS attachment, the advanced machine security system installation status should be set to "installed". A factory password is required to install this feature. H series models have this feature incorporated into the Transmission ECM. On the 980H this feature is called security system enable command and will be set to " Enabled" if the machine is equipped with MSS.

ReferenceService Manual, RENR2462, "Machine Security System"

Transmission Direction Switch #2 Type (950H to 972H)

The 950H through 972H machines may be equipped with a remote Forward-Neutral-Reverse (FNR) switch. The transmission direction switch #2 type should be set to "not installed" if the machine is not equipped with a remote Forward-Neutral-Reverse switch. If the machine is equipped with a remote FNR switch select "Type 1" if the switch is a 246-2642 Rocker Switch that is implement pod mounted. Select "Type 2" if the switch is a 303-9566 Rocker Switch that is a single axis lever with a pod mount or a joystick.

303-9566 Rocker Switch

Torque Converter Freewheel Stator Installation Status (980H)

The freewheel stator is standard on a 980H machine equipped with a standard transmission. The extreme service transmission or heavy duty transmission on 980H only, do not have a freewheel stator. The torque converter freewheel stator installation status should be set to "Installed" for machines with a standard transmission. The torque converter freewheel stator Installation status should be set to "Not Installed" for machines equipped with a heavy duty transmission.

Parking Brake Type (980H)

The heavy duty parking brake that is offered on the 980H provides an enclosed parking brake mounted on the transmission in place of the standard drive shaft parking brake. The heavy parking brake is only available with the heavy duty transmission. If the machine is equipped with a heavy duty parking brake, set the parking brake type to "Heavy Duty". If the machine is equipped with the standard parking brake the parking brake type should be set to "Standard".

Note: If a heavy duty parking brake is installed on the machine, the hold level calibration (clutch engagement calibration) and then the adjustment of ramp level (clutch fill calibration) will need to be performed on the machine using the 4C-8195 Control Service Tool . These calibrations can not be performed in ET on machines that are equipped with a heavy duty parking brake.

The calibration for the transmission clutch engagement must be performed prior to the transmission clutch fill calibration. The transmission clutch fill calibration will fine tune values for the clutch that is controlled by the valve. If the parameters for the clutch fill are not correct, the quality of the transmission shift can be greatly affected. In order to achieve greater consistency, the calibration procedure is automatic.

ReferenceFor the procedure to perform the transmission clutch engagement and fill calibration on machines that are equipped with a heavy-duty parking brake, refer to Special Instruction, REHS2466

Differential Lock Installation Configuration (938H)

The locking differential allows the differential to be locked and the mechanism enables the axle shafts of the universal joints to be locked together, both wheels can then rotate at the same speed regardless of different ground resistance between the wheels. The standard machine is equipped with a locking differential on the front axle only. The differential lock feature is available on the 938H. The differential lock installation configuration should be set to "Front".

Automatic Differential Lock Feature Installation Status (938H)

The automatic differential lock system will automatically operate in active mode and in passive mode. Active mode comes on when the machine is digging or in high rimpull, allowing engagement of the differential lock before the wheels begin to slip. When the differential lock system is not in "Active" mode, the" Passive" mode is enabled. In" Passive" mode, the system is constantly comparing actual wheel speeds with the calculated wheel speeds. If the system detects a wheel slip, the differential locks are engaged. The "passive" mode allows the machine to control the wheel slip in low torque and higher speed applications.

Machines that are equipped with the automatic locking differential will have both the front and the rear locking differentials. The system will engage the differential lock, if the automatic differential lock feature installation status is set to installed and the differential lock installation configuration is set to "Front and Rear". The automatic differential lock feature is available on the 938H.

Transmission Soft Shift Enable Status (980H)

Soft shift is available on the 980H. This feature affects the speed of engagement for the clutches during shifting. For the transmission soft shift enable status, select "enabled" for standard shift times. For faster shift times on 2-1, 3-2 and 2-3 shifts, set the transmission soft shift enable status to "disabled" and set the variable shift control switch in the cab to "normal". Soft shift cannot be disabled when variable shift control is set to "intermediate" or "economy" regardless of the soft shift enabled status.

Engine Idle Shutdown Installation Status (938H to 980H)

The Engine Idle Shutdown (EIS) shuts down the engine after the operator is not operating the machine for a period of time. This function does not shut down other systems, such as AC, which can run down the battery after idle shutdown. Engine Idle Shutdown may be required for local regulations. EIS shuts down the engine if the following conditions are met:

• Engine coolant temperature must be warm prior to the last start

• The parking brake is applied

• The left service brake is released

• The throttle pedal is released

• Gear is in neutral

• The implement is not active (This condition/control is not used for EIS on the 938H/IT38H)

An operator can activate any of the controls listed above in order to cancel the shut down. The recommended option for the operator is to use the left brake pedal in order to cancel a shutdown. EIS requires a factory password to be installed or uninstalled in ET. Once EIS is Installed in ET the" Engine Idles Shutdown Enable Status" in the engine configuration screen needs to be "Enabled" and the "Engine Idle Shutdown Delay Time " in the engine configuration screen can be programmed to the desired time before shutdown (in minutes).

The action lamp will light and an alarm will sound 20 seconds before the engine shuts down. On the 938H a message will also be displayed on the messenger display.

Raise Kickout Enable Status

This feature allows the linkage to stop at a programmed linkage height. For standard configuration machines this feature is enabled by default but, it can be disabled in ET.

Lower Kickout Enable Status

This feature allows the linkage to stop at a programmed linkage height. This kickout will be activated if the lift linkage is above the lower kickout cushion region, otherwise " FLOAT" will be activated. If lower kickout is disabled and "FLOAT" is enabled, when the lift lever is moved to the lower detent position, "FLOAT" will be active, and the implement control will not do a lower kickout. For standard configuration machines this feature is enabled by default but, can be disabled in ET.

Rackback Kickout Enable Status

This feature allows the worktool to stop at a programmed angle. This kickout is also known as the "Tilt Kickout", or "Return to Dig Kickout". For standard configuration machines this feature is enabled by default but, can be disabled in ET

Lift Cylinder Snubbing Enable Status

This feature provides an electronic cushion to cylinder stroke at full raise. If the cylinder enters the cushion zone and the lever is returned to the center position, then pulled to raise again, snubbing will not activate to allow full pressure to the end of stroke. The cylinder must be lowered out of the cushion zone to activate snubbing again. For standard configuration machines this feature is enabled by default but, can be disabled in ET.

Lift Linkage Float Enable Status

When the lift control lever or the joystick control is moved to the lower position beyond the lower kickout, the linkage will lower to the ground and oil from the rod end and the head end of the lift cylinder drains to the tank. The lift arm assembly will follow the contour of the ground. The float may be disabled independent of other features. It is possible to have the lower kickout enabled and have the float disabled. For standard configuration machines this feature is enabled by default but, can be disabled in ET.

Lift Linkage Feather Catch Enable Status

Feather Catch may also be referred to as cushioned catch. If the lift lever is moved to the "LOWER KICKOUT" position and the linkage begins to drop, then the lever is quickly returned to center, the linkage is cushioned to a stop (approximately four to five inches at the bucket tip). For standard configuration machines this feature is enabled by default but, it can be disabled in ET.

Dump Rate Control Enable Status

Dump rate control will provide a constant dump speed throughout the entire bucket travel while dumping. This feature will slow the dump speed, so it is disabled by default. This feature is only available with work tool set equal to bucket or quick coupler. For standard configuration machines this feature is disabled by default but, can be enabled in ET.

Full Rack Angle Control Enable Status

FRAC will roll the bucket forward slightly if fully racked back while raising the lift linkage. This is done to help prevent material from coming over the back of the bucket. This feature is not allowed to be "Enabled" if Payload Control (PCS) is installed, since that feature expects that the bucket be fully racked and not moving throughout the weigh range. This feature is only available with work tool configured to "Bucket" or "Quick Coupler". For standard configuration machines this feature is disabled by default but, can be enabled in ET.

Dump Stop Snubbing Enable Status

Dump stop snubbing is designed to prevent the lift cylinders from being retracted by a dumping motion when the tilt linkage in on the dump stops (fully dumped and lift linkage is high). It is not designed to cushion against the stops, just limit the dump valve current once actually on the stops. This feature is only available with the work tool set equal to bucket or quick coupler. For standard configuration machines this feature is disabled by default but, can be enabled in ET.

Autodig Installation Status

The Aggregate Autodig control system is an integrated attachment to the Electrohydraulic implement control system on Medium Wheel Loaders that is designed to automatically load aggregate materials of various sizes. There are three modes that the Autodig system can operate in.

Autodig is only available on machines with a pin on bucket. This attachment requires some additional hardware. Autodig is a premium feature that can be installed with a password but, by default is not installed on the machine.

Automatic Pile Detection Mode

This mode automatically starts bucket loading cycle.

Operator Triggered Mode

This mode allows the operator to manually activate bucket loading cycle.

Record Mode

This mode will utilize an operator recorded bucket loading cycle.

Note: The operator sets the type of material to be loaded, ranging from light to heavy, using the Dig Mode Selector. Autodig begins loading when the bucket is in the dig position and has contacted the pile. The operator maintains control of steering and the throttle at all times while Autodig controls the implement system during the bucket loading cycle. The operator can override Autodig at any time during the loading cycle by moving a control lever.
