DTC Descriptor

DTC B3101 00

- Keyless Entry Data Link Circuit

Diagnostic Fault Information

Circuit/System Description

The body control module (BCM) communicates with the remote control door lock receiver through the keyless entry serial data circuits. When any

button on the keyless entry transmitter is pressed, the transmitter sends a signal to the remote control door lock receiver. The remote control door

lock receiver sends a function request to the BCM, depending on which button is pressed on the transmitter. The BCM receives the message and

performs the appropriate function.

Conditions for Running the DTC

A button is pressed on the keyless entry transmitter.

Conditions for Setting the DTC

No response is received from the remote control door lock receiver after the BCM requests information from or sends configuration commands to

the remote control door lock receiver.

Action Taken When the DTC Sets

In the case of power failure, the remote control door lock receiver is disabled for 65 seconds, otherwise no action is taken.
