Remote Keyless Entry System: Notes

Following are tests that may help to diagnose the RKE system. However, these tests may not prove conclusive in the diagnosis of this system. In order to obtain conclusive testing of the RKE system, the CAN bus network and all of the electronic modules that provide inputs to, or receive outputs from the RKE system components must also be tested.

The most reliable, efficient, and accurate means to diagnose the RKE 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 RFH is being sent the proper Radio Frequency (RF) signals by the RKE transmitters (also known as FOB with Integrated Key/FOBIK) to perform its RKE system functions.

Refer to the appropriate wiring information. The wiring information includes appropriate SYSTEM WIRING DIAGRAMS, connector pin-out information and location views for the various wire harness connectors, splices and grounds.
