  2. Operate power door locks from door switches. If door locks operate correctly, go to next step. If door locks do not operate correctly, go to KEYLESS ENTRY & POWER DOOR LOCKS article.
  3. Using scan tool, select SYSTEM MONITORS, then CCD BUS TEST. If scan tool displays BUS OPERATIONAL, go to next step. If scan tool does not display BUS OPERATIONAL, go to appropriate VEHICLE COMMUNICATIONS test in VEHICLE COMMUNICATIONS article.
  4. Using scan tool, select THEFT ALARM, then MISCELLANEOUS. Select PROGRAM RKE. Follow scan tool instructions and program all transmitters. Operate door locks using transmitter. If door locks operate properly, test is complete. If door locks do not operate properly, go to next step.
  5. Ensure RKE transmitter batteries are fully charged. Replace as needed. Using scan tool, program transmitter. Follow scan tool instructions. Using RKE transmitter, operate door locks. If door locks operate correctly, test is complete. If door locks do not operate correctly, go to next step.
    6. NOTE: Remote Keyless Entry (RKE) module may also be known as overhead module.
  6. Disconnect RKE module connector. RKE module is mounted in roof or overhead console. Using voltmeter, measure voltage between ground and terminal No. 2 (Pink wire) on RKE module harness connector. If voltage is 10 volts or greater, go to next step. If voltage is less than 10 volts, repair open Pink wire.
  7. Connect jumper wire between ground and terminal No. 5 (Dark Blue wire) on RKE module harness connector. If door lock motor operates, go to next step. If door lock motor does not operate, go to step 10)  .
  8. Connect jumper wire between ground and terminal No. 11 (Light Blue/Red wire) on RKE module harness connector. If door lock motor operates, replace RKE module. If door lock motor does not operate, go to next step.
  9. Disconnect passenger door module 8-pin harness connector. Connect jumper wire between ground and terminals No. 5 and 11 on RKE module harness connector. Using ohmmeter, measure resistance between ground and terminal No. 2 (Dark Blue/Pink wire) on passenger door module 8-pin harness connector. If resistance is less than 5 ohms, go to step 12)  . If resistance is 5 ohms or greater, repair open Dark Blue/Pink wire.
  10. Disconnect passenger door module 8-pin harness connector. Connect jumper wire between ground and terminals No. 5 and 11 on RKE module harness connector. Using ohmmeter, measure resistance between ground and terminal No. 2 (Dark Blue/Pink wire) on passenger door module 8-pin harness connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open Dark Blue/Pink wire.
  11. Ensure passenger door module 8-pin harness connector is connected. Connect jumper wire between ground and terminal No. 11 (Light Blue/Red wire) on RKE module harness connector. If door lock motor operates, replace RKE module. If door lock motor does not operate, go to next step.
  12. Disconnect passenger door module 8-pin harness connector. Connect jumper wire between ground and terminals No. 5 and 11 on RKE module harness connector. Using ohmmeter, measure resistance between ground and terminal No. 1 (Light Blue/Red wire) on passenger door module 8-pin harness connector. If resistance is less than 5 ohms, replace passenger door module. If resistance is 5 ohms or greater, repair open Light Blue/Red wire.
