Was bedeutet der Fehlercode?
The engine control module (ECM) monitors the internal voltage circuits that feed the components and sets the code when the voltage in one circuit is too low. The check runs with the ignition on. The cause may be a short to ground in the wire, a damaged sensor or a damaged control module.
Mögliche Ursachen
- Voltage cable to a sensor shorted to ground
- Damaged sensor
- Damaged control module
Was Sie tun können
- 1Read the code, clear it and check that it is not active after the road test
- 2Check the sensor voltage cable for chafing and contact with ground; use a multimeter to confirm the cable has no contact with the body
- 3Check that the sensor connectors are fully engaged and free from oxidation
- 4If you have diagnostic equipment, read the sensor values in live data with the ignition on and see whether any one gives a too-low reading
- 5If the code remains after these checks, have a workshop decide whether the control module needs replacing
Symptome, die Sie bemerken können3
- The starter motor does not turn
- The starter cranks but the engine will not start
- Poor performance
