Passive Entry System
As a preliminary diagnosis for the Passive Entry (PE)/Keyless GO system, first check using the Electronic Vehicle Information Center (EVIC) or with a diagnostic scan tool to be certain that this Customer Programmable feature is enabled. Next, confirm that the power lock system and the RKE system operate satisfactorily. If the power lock system or the RKE system fails to operate correctly, repair that problem before attempting to diagnose the PE system.
The most reliable, efficient, and accurate means to diagnose the PE system requires the use of a diagnostic scan tool and the appropriate diagnostic information. The diagnostic scan tool can provide confirmation that the CAN data bus is functional, that all of the proper electronic modules are sending and receiving the proper electronic messages over the CAN data bus, and that the Radio Frequency Hub (also known as the RF Hub) is sending the proper Radio Frequency (RF) signals to and receiving the proper RF signals from the RKE transmitters (also known as FOB with Integrated Key/FOBIK) to perform its PE system functions.
Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
