Hva betyr feilkoden?
The CEM has registered faulty or altered engine control software (ECM). The fault can stop the engine from starting. It may be intermittent, and correct software is downloaded by a workshop.
Mulige årsaker
- An incorrect software checksum
Hva du kan gjøre
- 1With the ignition on, check whether the code returns after switching the ignition off and on again
- 2Has the owner altered the engine software? Discuss it first, since a change that did not cause the fault should not be corrected
- 3Check that the battery terminals and cable connections are clean and tight, so the control modules get stable voltage
- 4Software is downloaded with diagnostic equipment and can only be done by a workshop
Symptomer du kan merke1
- The engine does not start
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
