C-10, C-12 and C-15 On-Highway Engines Caterpillar

Customer Specified Parameters allow the vehicle owner to influence the operating technique of a driver. Some parameters may affect engine operation in a way that would not be expected by an inadequately trained driver. These parameters may lead to power or performance complaints even though the engine's performance is within the engine's specification.

Customer parameters may be changed repeatedly as a customer's operation changes or as new drivers are assigned to a truck. Customer Passwords are required to change these parameters.

The following information is a brief description of the Customer Specified Parameters. The following parameter values are included with the descriptions:

• Minimum

• Maximum

• Default

The tables show values in an approximate range for metric units that is followed by the metric conversion to English units. The exact range of the parameter in metric units depends on the service tool that is being used. Each tool may use slightly different conversion factors.

Customer Parameter Lockout

The Customer Parameter Lockout is available in order to restrict access to changing some of the available parameters. Locking out a parameter requires Customer Passwords (if used). Once a parameter is locked out, Factory Passwords are required to change the parameter. Also, once a parameter is locked out, Factory Passwords are required to unlock the parameter.

If a lockable parameter is not locked out, Factory Passwords are not required. A locked out parameter restricts the parameter from being changed directly by the operator. This helps vehicle owners that are encountering problems with operators that are obtaining Customer Passwords and altering some of these parameters.

A locked out parameter also provides an audit trail. The audit trail can be used to determine the following information:

• Time of change

• Operator during change

The following Customer Parameters are available for Lockout:

• "Multi-Torque Ratio"

• "Vehicle Speed Calibration"

• "Vehicle Speed Cal (J1939 - Trans)"

• "Vehicle Speed Cal (J1939 - ABS)"

• "Vehicle Speed Limit"

• "VSL Protection"

• "Soft Vehicle Speed Limit"

• "Low Speed Range Axle Ratio"

• "High Speed Range Axle Ratio"

• "Low Cruise Control Set Speed Limit"

• "High Cruise Control Set Speed Limit"

• "Top Engine Limit"

• "Transmission Style"

• "Top Gear Ratio"

• "Top Gear Minus One Ratio"

• "Top Gear Minus Two Ratio"

• "A/C Switch Fan On-Time"

• "Engine Retarder Delay"

• "Engine Monitoring Lamps"

• "Driver Reward Enable"

• "Fan Control Type"

When an attempt to change a locked out parameter occurs, the Factory Password screen will come up. If changing the parameter is required, follow the instructions on ET.

Factory Passwords are also required to change a parameter from a locked parameter to an unlocked parameter. If more than one parameter is locked out, and each one needs to be unlocked, one Factory Password is required.

Injector Codes

Injector Codes are etched on each injector for these engines. The Injector Codes can be viewed on Cat ET or the injector codes can be changed on Cat ET. Select the "Injector Codes Calibration" screen under the Service menu on Cat ET. The injector code must match the code on the corresponding injector. When an injector is replaced, reprogram the new code for the new injector. Refer to Troubleshooting, "Injector Codes - Calibrate".
