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.
Programming BCM
After a new BCM has been installed, insert one of the customer's keys into ignition lock cylinder, and turn it to ON position. Start engine to verify system operation. If SECURITY warning indicator illuminates for about 5 seconds and then goes out, BCM is programmed properly. If SECURITY warning indicator flashes (about one flash per second) until ignition switch is turned to OFF position, BCM did not program. Check for faulty system components and wiring.
