Was bedeutet der Fehlercode?
The engine control module (ECM) compares its configuration ID with the one the central electronics control module (CEM) sends out on the CAN network. Although the code is titled invalid signal, it applies when the configuration ID does not match the CEM's.
Mögliche Ursachen
- Wrong configuration ID because the module is not intended for the car, for example a used module with different software or hardware
- Break in the CAN wires between the module and the CEM
Was Sie tun können
- 1Check that the module is intended for this car, especially after replacement or if it is used
- 2Check the CAN connectors at the module and at the central electronics control module for oxidation and loose contacts
- 3Look for chafed CAN wires and use a multimeter to check that they have no break
- 4Have a workshop with diagnostic equipment check the configuration and reprogram the module if needed
Symptome, die Sie bemerken können2
- The cruise control does not engage
- Red warning symbol and text message in the display
Was der Fehler beeinflussen kann2
- The module shuts off from the CAN network (bus-off)
- The module still responds to diagnostic commands
