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.

The keyless entry system must be enabled and a test is ran every time the key is cycled.

The DTC is set if there are no keyless entry transmitter programmed to the RCDLR.

The keyless entry system is inoperative.

A current DTC is cleared when at least one transmitter has been programmed to the RCDLR.
