Hva betyr feilkoden?
On the V40, the CEM has rebooted too often within a single operating cycle. The code may be caused by low battery voltage at start-up, but also by a faulty module. Symptoms can include poor performance, difficulty starting, hesitation or incorrect gauge readings.
Mulige årsaker
- Low battery voltage at start-up
- Faulty control module
Hva du kan gjøre
- 1Check that the battery is in good condition and that the terminals and earth connections are tight
- 2With a diagnostic tool, cycle the ignition once, read the codes again and check whether the code was active in the last cycle
- 3If the code was not active during the last operating cycle it is intermittent and needs no action
- 4If the code was active in this cycle, have a workshop with diagnostic equipment check the module and replace it if needed
