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.
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.
Possible causes:
1)Open circuit in the engine harness, brake harness, or engine brake solenoids
2)Short to voltage source in the engine harness.
3)Malfunctioning ECM.
Possible repairs:
1)Replace the engine brake solenoid.
2)Replace the ECM.
3)Repair or replace the engine harness.
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.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 1969 PID: SPN: 3249 FMI: 0 Aftertreatment Exhaust Gas Temperature 2 – Data Valid but Above Normal Operational Range – Most Severe Level. The aftertreatment diesel particulate filter inlet temperature sensor reading has exceeded the maximum engine protection temperature limit.
