DTC B1323: Door Ajar Light Circuit Failure
- Check Indicator Light - Close all doors. Turn ignition on. If door ajar indicator light is not on at all times, go to step 4). If door ajar indicator light is on at all times, go to next step.
- Check Black/Orange Wire Circuit - Turn ignition off. Disconnect GEM harness connector C236. See Figure - Figure . Using an ohmmeter, measure resistance between ground and GEM harness connector C236 terminal No. 2 (Black/Orange wire). If resistance is 10 k/ohms or less, go to next step. If resistance is more than 10 k/ohms, replace GEM. Retest system.
- Check Black/Orange Wire For Short To Ground - Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Disconnect instrument cluster connector C250. See Figure - Figure . Measure resistance between ground and instrument cluster connector C250 terminal No. 14 (Black/Orange wire). If resistance is 10 k/ohms or less, repair short to ground in Black/Orange wire. Retest system. If resistance is more than 10 k/ohms, replace instrument cluster printed circuit. See PRINTED CIRCUIT under REMOVAL & INSTALLATION. Retest system.
- Check Black/Orange Wire For Open - Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Disconnect instrument cluster connector C250. See Figure - Figure . Measure resistance of Black/Orange wire between instrument cluster connector C250 terminal No. 14 and GEM harness connector C236 terminal No. 2. If resistance is less than 5 ohms, go to next step. If resistance is more than 5 ohms, repair open Black/Orange wire. Retest system.
- Check Bulb - Remove door ajar bulb from instrument cluster. Measure resistance of bulb. If resistance is more than 5 ohms, replace bulb. If resistance is less than 5 ohms, replace instrument cluster printed circuit. See PRINTED CIRCUIT under REMOVAL & INSTALLATION. Retest system.
