Was bedeutet der Fehlercode?
Despite the name signal too low, the code concerns the engine control module's own restart function. The module monitors this function continuously, and the code is set when a fault occurs in it. The fault therefore lies in the module, and when it tries to restart itself the engine may stall or fail to start altogether.
Mögliche Ursachen
- Software in the module is faulty
- Damaged module
Was Sie tun können
- 1Read the code, clear it and start the engine to see whether it returns
- 2Check that the battery terminals and the module connectors are fully seated and free from oxidation
- 3If the fault remains, a workshop should try new software in the module
- 4If the new software does not help, the module is damaged and must be replaced; both replacing and programming it is a job for a workshop
Symptome, die Sie bemerken können4
- Malfunction indicator lamp (MIL) is on
- Malfunction indicator lamp (MIL) flashes
- The engine stalls
- The engine cranks but will not start
Was der Fehler beeinflussen kann1
