Circuit/System Verification
- Verify all available keys are correct for the vehicle. This can be accomplished by comparing the part number that is laser etched on the key to the part number listed in the parts catalog.NOTE:
On some model year vehicles two learned keys are required to add additional keys. If only one learned key is used, this DTC will set. If only one learned key is available then Replacing Keys must be performed.
- If a key is not correct
Replace the key
- Go to next step: If all keys are correct
- If a key is not correct
- Verify the scan tool Immobilizer data displays two or more keys learned to the vehicle.
- If not
Add one additional key
- Go to next step: If two or more keys are learned to the vehicle
- If not
- Perform the Replacing Keys procedure. Refer to Key with Integrated Transmitter Programming .
- Verify the K9 Body Control Module learns the vehicle key and exits the learn coded key state. The scan tool Master Keys Learned parameter should increment to 1.
- If the K9 Body Control Module does not exit the learn coded key state after the programming attempt
Replace the K9 Body Control Module
- Go to next step: If the K9 Body Control Module exits the learn coded key state after the programming attempt
- If the K9 Body Control Module does not exit the learn coded key state after the programming attempt
- All OK.
