Hva betyr feilkoden?
The ECM compares the voltage on its +15 supply with the battery voltage. If the difference between them is too large, fault code ECM-182B is set. The fault may lie in the connectors of the supply to the control module.
Mulige årsaker
- Faulty signal from the supply
- Contact resistance in the connections
Hva du kan gjøre
- 1Switch off the ignition and check the connectors in the supply to the control module for play, contact resistance and oxidation
- 2Check that the battery terminals and the earth points are tight and clean
- 3If you have a diagnostic tool: check in live data that the +15 supply voltage is close to the battery voltage with the ignition on
- 4If the fault remains, have a workshop check the supply to the control module
Symptomer du kan merke1
- No noticeable symptoms for the driver
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
