The Engine Control Module (ECM) detects the following conditions: •The vehicle speed slows at a rate that exceeds the “Quick Stop Rate” that is programmed.•The service brake is applied. Probable Causes: •The parameter for the “Quick Stop Rate” may be set too low. Note: This setting can be affected by the load on the vehicle. If the vehicle is operated without a trailer or with no load, the vehicle will stop faster than the same vehicle with a heavy load.

The Engine Control Module (ECM) detects one of the following conditions: •The “Allow Idle Shutdown Override” parameter is programmed to “Yes” and the status of the brake switch or the clutch switch changes.•The “Allow Idle Shutdown Override” parameter is programmed to “J1587 Outside Temp Based” or “Outside Temperature Based”. The outside temperature is above the maximum programmed temperature or the outside temperature is below the minimum programmed temperature.•The idle shutdown timer is within the final 90 seconds.•The “Idle Shutdown Time” parameter is programmed to at least three minutes. Probable Causes: 1) It code 84-08 is active, Idle Shutdown Timer will...

The ECM detects the following conditions: •The coolant level sensor is sending an invalid signal for more than ten seconds.•The “Coolant Level Sensor” parameter is programmed to “Yes”. Probable Causes: 1) ECM Connection/Harness2) Coolant sensor failure3) Coolant sensor harness failure4) ECM Failure

The Engine Control Module (ECM) detects the following conditions: •The signal voltage from the coolant level sensor is greater than 4.5 VDC for more than ten seconds.•The “Coolant Level Sensor” parameter is programmed to “2-wire Float Sensor”.•The ECM has been powered for at least two seconds. Probable Causes: 1) Coolant Level Sensor2) Coolant Level sensor wiring3) ECM failure
