IMPORTANT:
A new RCDLR installed in a vehicle will require having both the SCLM and ECM learn the new RCDLR password. Perform the 10-minute relearn procedure for each module to learn the password of the new RCDLR. The SCLM password learn must be performed first to ensure proper completion of the learn process.
When replacing an engine control module (ECM) or steering column lock module (SCLM) with a GM SPO replacement part, the new ECM or SCLM will learn the incoming password of the remote control door lock receiver (RCDLR) immediately upon the next ignition switch from OFF to CRANK. If the ECM or SCLM is being replaced with an SPO replacement part, the theft deterrent password learn procedure is not required.
An ECM or SCLM which has been installed in another vehicle will have learned the theft deterrent password of that particular vehicles RCDLR. Perform the 10-minute relearn procedure to learn the password of the current vehicles RCDLR.
