Test S: Seat Belt Warning Chime Inoperative
- Turn ignition switch to LOCK position. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). Using NGS tester, monitor Generic Electronic Module (GEM) PID D_SBELT while buckling and unbuckling driver's seat belt. If PID always indicates FSTND, go to next step. If PID always indicates UNFSTD, go to step 3 . If PID agrees with seat belt position, replace GEM.
- Turn ignition switch to LOCK position. Disconnect GEM harness connector C248. Measure resistance between ground and terminal No. 5 (Brown/Light Blue wire) at GEM harness connector C248. See Figure . If resistance is 10 k/ohms or less, go to step 6 . If resistance is greater than 10 k/ohms, replace GEM.
- Turn ignition switch to LOCK position. Disconnect GEM harness connector C248. Measure voltage at terminal No. 5 (Brown/Light Blue wire) at GEM harness connector C248. See Figure . If voltage does not exist, go to next step. If voltage exists, repair short to voltage in Brown/Light Blue wire.
- Disconnect driver's seat belt switch harness connector C302. Measure resistance between ground and Black wire terminal at driver's seat belt switch harness connector C302. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Black wire.
- Measure resistance in Brown/Light Blue wire between driver's seat belt switch harness connector C302 and terminal No. 5 at GEM harness connector C248. If resistance is 5 ohms or less, go to step 7 . If resistance is greater than 5 ohms, repair open in Brown/Light Blue wire.
- Measure resistance between terminals at driver's seat belt switch (component side) while buckling and unbuckling driver's seat belt. Resistance should be 5 ohms or less when seat belt is buckled and greater than 10 k/ohms when seat belt is unbuckled. If resistance is as specified, repair short to ground in Brown/Light Blue wire. If resistance is not as specified, replace driver's seat belt switch.
- Measure resistance between terminals at driver's seat belt switch (component side) while buckling and unbuckling driver's seat belt. Resistance should be 5 ohms or less when seat belt is buckled and greater than 10 k/ohms when seat belt is unbuckled. If resistance is as specified, replace GEM. If resistance is not as specified, replace driver's seat belt switch.
