Test AK: Seat Belt Warning Chime Not Operating Properly

  1. Turn ignition switch to LOCK position. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). DLC is located below left side of instrument panel, to right of steering column. Using NGS tester, monitor instrument cluster PID D_SBELT while buckling and unbuckling driver's seat belt. With seat belt buckled, PID should display IN. Without seat belt buckled, PID should display OUT. If PID only displays OUT, go to next step. If PID only displays IN, go to step  5 . If PID displays as described, replace instrument cluster.
  2. Turn ignition switch to LOCK position. Disconnect driver's seat belt switch harness connector C381. Measure resistance between ground and driver's seat belt switch harness connector terminal No. 2 (Black wire). If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in Black wire between driver's seat belt switch and ground. Ground point is located, on floor of vehicle under drivers seat.
  3. Using a fused jumper wire, ground driver's seat belt switch harness connector terminal No. 1 (White/Black wire). Turn ignition switch to RUN position. Using NGS tester, monitor instrument cluster PID D_SBELT. If PID displays OUT, go to next step. If PID does not display OUT, replace driver's seat belt switch.
  4. Turn ignition switch to LOCK position. Disconnect instrument cluster 22-pin harness connector C220a. Measure resistance in White/Black wire between driver's seat belt switch harness connector terminal No. 1 and instrument cluster harness connector C220a terminal No. 18. See Figure . If resistance is more than 5 ohms, repair open in White/Black wire between instrument cluster and driver's seat belt switch. If resistance is 5 ohms or less, replace instrument cluster.
  5. Turn ignition switch to LOCK position. Disconnect driver's seat belt switch harness connector C381. Turn ignition switch to RUN position. Using NGS tester, monitor instrument cluster PID D_SBELT. If PID displays IN, go to next step. If PID does not display IN, replace seat belt buckle.
  6. Turn ignition switch to LOCK position. Disconnect instrument cluster 22-pin harness connector C220a. Measure resistance between ground and instrument cluster harness connector C220a terminal No. 18 (White/Black wire). See Figure . If resistance is 10 k/ohms or less, repair short to ground in White/Black wire between instrument cluster and driver's seat belt switch. If resistance is more than 10 k/ohms, replace instrument cluster.
