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.
This fault occurs whenever the ECM has been receiving SAE J1939 datalink commands from an external OEM device and is no longer receiving the datalink commands. Possible causes of this fault include:
1)Electrical problems with the SAE J1939 data link wiring such as grounded, shorted, or open circuits
2)The ECM (or another SAE J1939 device) tying up communications by sending too many consecutive messages
3)The external OEM controlling device has failed or can no longer transmit on the datalink.
Possible repairs:
1)Clean the connector and pins.
2)Repair the damaged harness connector, or pins, if possible.
3)Replace the OEM harness.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 418 PID: 97 SPN: 97 FMI: 0 Water-In-Fuel Indicator – Data Valid but Above Normal Operatibng Range – Least Severe Level. Water has been detected in the fuel filter.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 415 PID: 100 SPN: 100 FMI: 1 Engine Oil Rifle Pressure – Data Valid But Below Normal Operating Range – Most Severe Level. Oil pressure signal indicates oil pressure is below the engine protection critical limit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 386 PID: SID 212 SPN: 3509 FMI: 3 Sensor Supply 1 Circuit – Voltage Above Normal or Shorted to High Source. High voltage detected at sensor supply number 1 circuit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 352 PID: SID 212 SPN: 3509 FMI: 4 Sensor Supply 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected at sensor supply number 1 circuit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 351 PID: SID 251 SPN: 627 FMI: 12 Injector Power Supply – Bad Intelligent Device or Component. The ECM measured injector boost voltage is low.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 343 PID: SID 254 SPN: 629 FMI: 12 Electronic Control Module Warning Internal Hardware Failure – Bad Intelligent Device or Component. ECM power supply errors have been detected
