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 Description
Both the steering column lock control module (SCLCM) and the remote control door lock receiver (RCDLR) have passwords stored in memory, that are required to match in order to unlock the steering column. When the ignition is turned ON, the SCLCM receives a password from the RCDLR on the class 2 serial data bus. The SCLCM will unlock the steering column if the power mode is on and the SCLCM and RCDLR passwords match. If the SCLCM and RCDLR passwords do not match, the steering column will not unlock and DTC B2910 will set.
