Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
1)A short circuit to ground in the engine harness, connector, or engine brake solenoids.
1)Replace the engine brake harness.
2)Replace the engine harness.
3)Replace the engine brake solenoid.
4)Replace the ECM.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2182 PID: SID 79 SPN: 1072 FMI: 3 Engine Brake Actuator Driver 1 Circuit – Voltage Above Normal or Shorted to High Source. High voltage or open circuit detected at the engine brake solenoid number 1 signal circuit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 1993 PID: SPN: 3064 FMI: 11 Aftertreatment Particulate Trap Missing – Condition Exists. The aftertreatment diesel particulate filter in the exhaust system is not present.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 1981 PID: SID 324 SPN: 3926 FMI: 0 Aftertreatment Particulate Filter Differential Pressure – Data Valid but Above Normal Operational Range – Least Severe Level. The aftertreatment differential pressure has exceeded the maximum operating limits or the diesel particulate filter is plugged.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 1974 PID: 101 SPN: 101 FMI: 0 Crankcase Pressure – Data Valid but Above Normal Operational Range – Least Severe Level. The crankcase breather filter requires maintenance.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 1973 PID: SPN: 3245 FMI: 0 Exhaust Gas Temperature 3 – Data Valid but Above Normal Operational Range – Most Severe Level. The aftertreatment diesel particulate filter outlet temperature sensor reading has exceeded the maximum engine protection temperature limit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 1972 PID: SPN: 3245 FMI: 0 Exhaust Gas Temperature 3 – Data Valid but Above Normal Operational Range – Moderately Severe Level. The aftertreatment diesel particulate filter outlet temperature sensor reading has exceeded the maximum temperature limit.
