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 status of DTC B3102. If DTC is current, go to next step. If DTC is not current, check for intermittent problem. See DIAGNOSING INTERMITTENTS  . Repair or replace as necessary and go to step  9 .
  3. Turn ignition switch to OFF position. Disconnect RCDLR connector. See Figure . Measure voltage between RCDLR harness connector terminal No. 2 (Light Green wire) and ground. See Figure . Turn ignition switch to RUN position. If battery voltage is not present, go to next step. If battery voltage is present, go to step  5 .

    7. 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.
  7. Replace RCDLR. See REMOTE CONTROL DOOR LOCK RECEIVER  under REMOVAL & INSTALLATION. Program and synchronize transmitters to new RCDLR. See RKE TRANSMITTER PROGRAMMING  and TRANSMITTER SYNCHRONIZATION  under PROGRAMMING. After repair, go to step  9 .
