Was bedeutet der Fehlercode?

Before the engine is allowed to start, the ECM compares the immobilizer code with the CEM and also checks its own serial number against the BCM's. The fault is set if the supply drops during the check or if the numbers do not match. The engine will not start. The fault applies to the C30, C70 (06-), S40 (04-) and V50.

Mögliche Ursachen

Low battery voltage
Poor contact, corrosion or contact resistance at the ECM connector
Short to ground or open circuit in the supply or earth wire to the ECM
Break in the CAN wiring
Wrong ignition key
BCM not intended for this car, for example a used module with other software or hardware

Was Sie tun können

1Check that you are using the correct ignition key and that the battery voltage is normal
2Check the ECM connector for looseness, contact resistance and corrosion
3With a multimeter, check that the ECM supply wire is not shorted to ground and has no open circuit
4Visually inspect the CAN wiring for breaks and chafing
5Work on the brake control module (BCM) should go to a workshop, as it controls the braking system; a workshop can compare the serial numbers
