Test L: Smart Lock Malfunction

  1. Turn ignition switch to LOCK position. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC is located beneath instrument panel, right of steering column. Turn ignition switch to RUN position. Perform Front Electronic Module (FEM) self-test. If no DTCs are retrieved, go to next step. If any FEM DTCs are retrieved, performed appropriate test in accordance with DTC retrieved. See FRONT ELECTRONIC MODULE DIAGNOSTIC TROUBLE CODE INDEX  table under SELF-DIAGNOSTIC SYSTEM.
  2. Using NGS tester, monitor FEM PID D_DOOR. Close all doors. If FEM PID agrees with driver's door position, go to next step. If FEM PID does not agree with driver's door position, inspect driver's door ajar switch circuits for opens or shorts. See ILLUMINATION/INTERIOR LIGHTS article in WIRING DIAGRAMS.
  3. Disconnect driver's door ajar switch harness connector. Using NGS tester, monitor FEM PID D_DOOR. If FEM PID still indicates AJAR, go to next step. If FEM PID does not indicate AJAR, replace driver's door ajar switch.
  4. Turn ignition switch to LOCK position. Disconnect FEM harness connector C346 (20-pin). See Figure . Measure resistance between ground and FEM harness connector C346 terminal No. 8 (Light Green/Black wire). See Figure . If resistance is 10 k/ohms or more, go to next step. If resistance is less than 10 k/ohms, repair short to ground in Light Green/Black wire circuit between FEM and driver's door ajar switch.
  5. Disconnect all FEM harness connectors. Inspect for corrosion and pushed out pins. Connect all FEM harness connectors. Operate system to verify if concern is still present. If concern is still present, replace FEM. Clear DTCs and repeat FEM self-test. If concern is not present, system is operating correctly at this time. Clear DTCs and repeat FEM self-test.
