Does the car start with all keys?
Yes - Fault-tracing information
No - Programming keys
------------------------
Fault-tracing information
The control module has read and not approved a transponder code because it was not stored. That can be because of the following:
- There are several Volvo keys with transponders to the same car or other cars on the key ring. The control module reads the key code from the wrong key or a mixture of codes from several keys when attempting to start the car.
These keys should be separate so that they do not touch the key being used.
- An attempt has been made to start the car with a Volvo key programmed for a generation 3 immobilizer.
- An attempt has been made to start the car with a Volvo key before it was programmed into the control module as an approved key to the car.
- An attempt has been made to start the car with a Volvo key that is not one of the approved keys for the car.
- The fault was caused by a temporary disruption to communication between the transponder and the control module.
