Circuit/System Description

WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 GMC Cab & Chassis Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

The remote control door lock receiver (RCDLR) monitors the number of keyless entry transmitters programmed. Until at least one transmitter is programmed, the RCDLR determines a malfunction condition exists.
