Doors Do Not Operate Using Interior Door Lock Switches

  1. Access RKEM located in trunk, behind left side trim panel. Disconnect RKEM connector C3 (Grey connector). See Figure . Measure voltage between ground and RKEM connector C3, terminal No. 4 (Pink/Yellow wire). If battery voltage exists, repair short to battery voltage in Pink/Yellow wire. If battery voltage does not exist, go to next step.
  2. Measure voltage between ground and RKEM connector C3, terminal No. 5 (Pink/Light Green wire). If battery voltage exists, repair short to battery voltage in Pink/Light Green wire. If battery voltage does not exist, go to next step.
  3. Remove and disconnect door lock switch connectors. Measure resistance between ground and Black wires on both door lock switches. If resistance is less than 5 ohms on all Black wires, go to next step. If resistance is more than 5 ohms on any Black wire, repair open in Black wire in question. See WIRING DIAGRAM  .
  4. Install jumper wire between left door lock switch Pink/Light Green wire and Black wire. Measure resistance between ground and RKEM connector C3, terminal No. 5 (Pink/Light Green wire). Install jumper wire between right door lock switch Pink/Light Green wire and Black wire. Measure resistance between ground and RKEM connector C3, terminal No. 5 (Pink/Light Green wire). If resistance in both tests is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in Pink/Light Green wire. See WIRING DIAGRAM  .
  5. Install jumper wire between left door lock switch Pink/Yellow wire and Black wire. Measure resistance between ground and RKEM connector C3, terminal No. 4 (Pink/Yellow wire). Install jumper wire between right door lock switch Pink/Yellow wire and Black wire. Measure resistance between ground and RKEM connector C3, terminal No. 4 (Pink/Yellow wire). If resistance is 5 ohms or less in both tests, go to next step. If resistance is more than 5 ohms in both tests, repair open in Pink/Yellow wire. See WIRING DIAGRAM  .
  6. Measure resistance between each door lock switch Black wire and Pink/Light Green wire with LOCK side of switch depressed. Measure resistance between each door lock switch Black wire and Pink/Yellow wire with UNLOCK side of switch depressed. Resistance should be less than 5 ohms with switch depressed in each position and more than 10 k/ohms with switch released. If switch functions as described, go to next step. If switch does not function as described, replace switch in question.
  7. Disconnect right and left door lock actuator connectors. Measure resistance between RKEM connector C3, terminal No. 3 (Red/Orange wire) and left door lock actuator connector Red/Orange wire. Measure resistance between RKEM connector C3, terminal No. 3 (Pink/Orange wire) and right door lock actuator connector Pink/Orange wire. Measure resistance between RKEM connector C3, terminal No. 16 (Pink/Black wire) and Pink/Black wire at both door lock actuator connectors. Measure resistance between RKEM connector C3, terminal No. 2 (Pink/Black wire) and Pink/Black wire at both door lock actuator connectors. If resistance in all tests is less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair wire(s) in question and retest system. See WIRING DIAGRAM  .
  8. Measure resistance between ground and RKEM connector C3, terminal No. 2 (Pink/Black wire). Measure resistance between ground and RKEM connector C3, terminal No. 3 (Red/Orange wire). Measure resistance between ground and RKEM connector C3, terminal No. 6 (Pink/Orange wire). Measure resistance between ground and RKEM connector C3, terminal No. 16 (Pink/Black wire). If resistance is less than 10 k/ohms, repair short to ground in wire in question and retest system. See WIRING DIAGRAM  . If resistance is more than 10 k/ohms, go to next step.
  9. Apply battery positive and negative to each door lock actuator connector using 10 gauge, fused jumper wires. Actuator should lock or unlock. Reverse jumper wires. Actuator should move in opposite direction. If actuator operates as specified, go to next step. If actuator does not operate as specified, replace suspect actuator as necessary and retest system.
  10. Using an ammeter, measure current draw of each door lock actuator as it is cycled open and closed. If current draw is 6 amps or less, temporarily substitute known good RKEM, then retest system. If current draw is more than 6 amps, replace door lock actuator in question and retest system.
