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.
Preliminary Diagnosis
As a preliminary diagnosis for the RKE system, first confirm that the power lock system operates satisfactorily. If the power lock system fails to operate correctly, repair that problem before attempting to diagnose the RKE system. Next, note the RKE system operation while you perform both the Lock and Unlock functions with the RKE transmitter. Then, proceed as follows:
- If the power lock system functions with the power lock switch, but not with the RKE transmitter, proceed to diagnosis of the RKE transmitter.
- If the RKE transmitter checks okay, proceed to diagnosis of the BCM. The use of a diagnostic scan tool and the appropriate diagnostic information are required.
