Co oznacza ten kod błędu?
The four-wheel drive control module (DEM) continuously monitors that the voltage supplied to it is reasonable. The code is stored when the voltage is too high, which can be caused by excessive charging voltage from a damaged alternator. The four-wheel drive is disengaged while the fault is present and for a short time afterwards.
Możliwe przyczyny
- Damaged alternator
Co możesz zrobić
- 1Read and erase the code, then road test to see whether it returns
- 2Check that the fuses are intact
- 3If you have a diagnostic tool, read the control module voltage with the ignition on; it should be close to the battery voltage. Then start the engine and read it again
- 4If the voltage rises too much while the engine runs, have a workshop check the alternator charging
- 5After replacing the four-wheel drive control module, the oil pressure pump or the clutch package, the control module must be calibrated, which a workshop should do
Objawy, które możesz zauważyć2
- The four-wheel drive does not work
- Warning symbol and message in the display
Na co może wpływać usterka1
- The four-wheel drive is disengaged while the fault is present and for a short time after it has cleared
