The Ignition Key Cannot Be Turned to the Lock Position

The Ignition Key Cannot Be Turned To The LOCK Position

Cars affected: Saab 9-3 M06-, or if the CIM has been replaced in older cars

Fault symptoms

The ignition key cannot be turned to the LOCK position and the key cannot be withdrawn from the ignition switch.

Cause: If the ignition key has been turned from ON to OFF at a speed above 5 km/h then the key cannot be turned to the LOCK position and so cannot be withdrawn from the ignition switch. The reason for this is that the CIM stops sending out + X-feed to the TCS/ESP which in turn stops sending the speed signal and the latest speed then remains stored. In this situation, key-turning is not permitted.

Procedure

1. If the ignition key cannot be turned to LOCK, turn it back to the ON position. Wait for approx. 2 seconds. Then turn it back to the LOCK position.
2. Inform the customer about the function.

Fault diagnosis procedure is not available.
