Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Verification
- 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 Replacing Keys (without BTM) .
- 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.
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.
