Diagnostic Fault Information
Circuit/System Description
The system is designed so that when the operator approaches a locked vehicle with the keyless entry transmitter, the keyless entry control module
will detect the keyless entry transmitter and when an exterior door handle is pulled the keyless entry control module will command all doors to
unlock and the door to unlatch allowing the door to be pulled open.
