Co oznacza ten kod błędu?
The ECM receives the information about the cruise control buttons from the central electronics module (CEM) over CAN and checks that it is reasonable. Each message should carry a sequence number that counts up, and here the number does not match. The code is set when the information from the CEM is faulty or unreasonable.
Możliwe przyczyny
- The fault may lie in the central electronics module (CEM)
Co możesz zrobić
- 1Check that the fuses are intact
- 2If you have diagnostic equipment: read the fault codes in the central electronics module (CEM) and deal with them first
- 3Test the cruise control buttons on the steering wheel and check that they spring back and do not stick
- 4Check that the connectors to the central electronics module (CEM) are firmly seated and not corroded
- 5If none of the checks shows anything, have a workshop look for the fault in the central electronics module (CEM)
Objawy, które możesz zauważyć2
- Cruise control does not engage
- Cruise control does not hold the set speed and disengages
Na co może wpływać usterka1
- Cruise control is switched off while the fault is active
