Test B: Keyless Entry System Inoperative

  1. Resynchronize all transmitters. See TRANSMITTER RESYNCHRONIZATION  under PROGRAMMING. If door locks cycle while resynchronizing transmitters, go to next step. If door locks do not cycle while resynchronizing transmitter, go to step  3 .
  2. Test system using RKE transmitters. If RKE system operates, system okay. Verify system operation. If RKE system does not operate, go to step  4 .
  3. Check voltage of RKE transmitter batteries. If voltage is 3.0-3.5 volts, go to step  5 . If voltage is not 3.0-3.5 volts, go to step  6 .
  4. Operate door locks using door lock switches. If doors lock operate normally, go to step  7 . If door locks do not operate normally, see appropriate POWER DOOR LOCKS article.
  5. Reprogram all transmitters. See TRANSMITTER PROGRAMMING  under PROGRAMMING. Test system using RKE transmitter. If RKE system operates normally, system okay. Verify system operation. If RKE system does not operate normally, go to step  8 .
  6. Replace transmitter batteries. Resynchronize transmitter. See TRANSMITTER RESYNCHRONIZATION  under PROGRAMMING. If door locks cycle during resynchronization of transmitters, go to step  2 . If door locks did not cycle during resynchronization of transmitters, go to step  8 .
  7. Reprogram all transmitters. See TRANSMITTER PROGRAMMING  under PROGRAMMING. Using RKE transmitter, test system operation. If keyless entry system works properly, system okay. If keyless entry system does not work properly, go to step  9 .
  8. Program known good transmitter. See TRANSMITTER PROGRAMMING  under PROGRAMMING. Using RKE transmitter, test system operation. If keyless entry system works properly, go to next step. If keyless entry system does not work properly, go to step  10 .
  9. Replace defective RKE transmitter. Verify system operation.
  10. Disconnect remote control door lock receiver (RCDLR) Black 8-pin connector. Using test light, backprobe RCDLR connector terminal "A" (Black wire) and terminal "C" (Orange wire). See Figure . If test light illuminates, go to next step. If test light does not illuminate, go to step  10 .
  11. Check for poor connection at RCDLR. If okay, replace RCDLR. See REMOTE CONTROL DOOR LOCK RECEIVER  under REMOVAL & INSTALLATION. Verify system operation.
  12. Using test light, backprobe between ground and RCDLR connector terminal "C" (Orange wire). See Figure . If test light illuminates, go to next step. If test light does not illuminate, go to step  14 .
  13. Repair poor connection or open in Black wire between RCDLR and ground. See WIRING DIAGRAMS  . Verify system operation.
  14. Repair poor connection or open in Orange wire between RCDLR and ground. See WIRING DIAGRAMS  . Verify system operation.
