15A RKE Unable to Enter Program Mode Trouble Code

Perform Test 1A Before Proceeding

NAME OF CODE
RKE Unable to Enter Program Mode

WHEN MONITORED
While attempting to program RKE

SET CONDITION
Lack of response from RKE module when attempting to put it in program mode

THEORY OF OPERATION
There are two communication lines between the BCM and the plug-on RKE module: a data line from the RKE to the BCM, and a program line, from the BCM to the RKE module. When operating properly, the BCM will receive an acknowledgement from the RKE, through the data line, that it recognized the request to enter program mode. It this acknowledgement is not received, the fault is set.

PROBABLE CAUSES
- Failed RKE module
- Failed BCM

NOTE: There are no wires to be cut or shorted; the two connectors connect directly to each other.
