Hva betyr feilkoden?
The engine control module (ECM) controls the cooling fan with a PWM signal through the fan control module, and can detect faults in the signal wire between them. The code concerns the signal wire, which is shorted to ground. The fault is recorded in the engine control module. There are related codes for the same circuit, ECM-P147412 and ECM-P147413, which may appear instead depending on the fault.
Mulige årsaker
- The signal wire between the engine control module (ECM) and the fan control module is shorted to ground
Hva du kan gjøre
- 1Check that the fuses are intact. Their location is in the owner's manual or on the fuse box cover.
- 2Check the connectors between the engine control module and the fan control module for looseness, contact resistance and corrosion.
- 3With the ignition off, use a multimeter to check that the signal wire between them has no contact with ground (the body).
- 4Check that the wire is not chafed or pinched, especially where it runs close to the body.
- 5If you have a diagnostic tool, activate the cooling fan and check that it starts when you send the command.
- 6If the code returns, have a workshop check the fan control module and the engine control module.
Symptomer du kan merke1
- The engine runs hot or overheats
Hva feilen kan påvirke1
