"Dash - PM 1 Reset"

This parameter determines if Messenger can be used to reset the PM 1 maintenance interval. The "Maintenance Indicator Mode" cannot be programmed to "OFF" for the PM 1 reset parameter to take effect.

"Dash - Customer Parameters"

Four parameters can be accessed when this parameter is programmed to "Yes". Messenger is used to change the "Dash - Customer" parameters. The following four parameters can be accessed:

• "SoftCruise Control"

• "Fast Idle RPM #1"

• "Fast Idle RPM #2"

• "Low Idle Engine RPM"

Each parameter that is listed has a "Yes/No" option with "No" as the default.

"Theft Deterrent System Control"

When this parameter is used with a "Theft Deterrent Password", this parameter prevents the engine from starting unless the password has been entered into Messenger. Before the operator can use the feature of theft deterrent in Messenger, the system must be turned on. In order to turn on the theft deterrent, a service tool must be used to program the parameter for the theft deterrent to Yes. The operator must first enter the password before the engine is shut off. This will enable the system. Enabling the system prevents the engine from starting without re-entering the password on the next attempted start. If this parameter is programmed to the "Auto-Enable" option, the system will automatically be armed when the keyswitch is turned off.

"Theft Deterrent Password"

The "Theft Deterrent Password" is the password that is required by the Engine Control Module (ECM) before the feature of theft deterrent is enabled. After the theft deterrent is enabled, the "Theft Deterrent Password" is the password that is required to restart the engine. All of the characters must be uppercase. Four characters are available for the password. If the password is lost, a service tool and a factory password are required in order to start the engine.

"Quick Stop Rate"

This parameter determines the rate of vehicle speed change that is used by the ECM to record a quick stop event code and a quick stop snapshot. Programming this parameter to zero will disable this feature and no quick stop events will be logged. Each quick stop snapshot contains 60 frames of information. Frame 45 is the quick stop event. The quick stop snapshot also contains 44 frames before the quick stop event and 15 frames after the quick stop event. Each frame is separated by 1.0 second.

The most recent quick stop snapshot is stored in the ECM memory. When a quick stop event occurs the ECM replaces the old quick stop snapshot with the new quick stop snapshot. The ECM also logs a diagnostic event code for each quick stop event. The ECM stores a maximum of 255 occurrences.

Note: Programming the "Quick Stop Rate" too low will cause an excessive number of quick stop event codes. A vehicle without a load or a trailer will be able to stop much more quickly than a vehicle with a heavy load. If too many quick stop event codes are being logged, increase the "Quick Stop Rate". This will improve the detection of the exceptions when the exceptions occur.
