Diagnostic Procedure

  1. Perform RKE system diagnostic system check. See REMOTE KEYLESS ENTRY SYSTEM DIAGNOSTIC SYSTEM CHECK  under SELF-DIAGNOSTIC SYSTEM. If RKE system diagnostic system check has been performed, go to next step.
  2. Connect scan tool to Data Link Connector (DLC). Turn ignition switch to RUN position. Using scan tool, check for DTC B1003, B3102 or B3103. If scan tool does not display DTCs, go to DIAGNOSTIC TROUBLE CODE DEFINITIONS  under SELF-DIAGNOSTIC SYSTEM. If scan tool displays DTCs, go to next step.
    3. NOTE: All RKE transmitters recognized by RCDLR must be programmed during programming sequence. If system is placed in program mode, it will erase all previously programmed RKE transmitters upon receipt of programming signal from first transmitter.
