Test A: All Power Windows Are Inoperative
NOTE:
This test is associated with DTCs B1302, B1304, B1313, B1315 and B1342.
- Check GEM/CTM PID IGN_GEM - Turn ignition off. Using NGS tester, access GEM/CTM PID IGN_GEM. Monitor GEM/CTM PID IGN_GEM while rotating ignition switch through START, RUN, OFF and ACC positions. If PID values agree with ignition switch positions, go to next step. If PID values do not agree with ignition switch positions, repair or replace ignition switch and retest system operation.
- Check DTCs - Using NGS tester, retrieve and record continuous DTCs from GEM/CTM. Clear DTCs. Using NGS tester, perform On-Demand self-test. If no DTCs are present, go to next step. If DTCs B1302 and B1304 are present, go to step 4). If DTCs B1313 and B1315 are present, go to next step. If DTC B1342 is present, replace GEM. Clear DTCs and retest operation.
- Check GEM/CTM PID BATSAV - Turn ignition switch to RUN position. Using NGS tester, access GEM/CTM PID BATSAV. Monitor GEM/CTM PID BATSAV while triggering GEM/CTM active command BATTSAVR on and off. If GEM/CTM PID BATSAV values agree with command mode, go to next step. If NGS tester indicates OFFO-G or ON-B-, repair appropriate battery saver relay circuit. See appropriate wiring diagram in ILLUMINATION/INTERIOR LIGHTS article.
- Check GEM/CTM PID ACCDLY - Using NGS tester, access GEM/CTM PID ACCDLY. Monitor GEM/CTM PID ACCDLY while triggering GEM/CTM active command ACCY RLY on and off. If NGS tester indicates OFFO-G, go to next step. If NGS tester indicates ON-B-, go to step 8). If GEM/CTM PID ACCDLY values agree with command mode, go to step 10).
- Check Light Green/Orange Wire For Voltage - Turn ignition off. Remove accessory delay relay (located under right side of instrument panel, behind glove box). Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 86 (Light Green/Orange wire). See Fig 1. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair Light Green/Orange wire and retest system operation.
- Check Accessory Delay Relay - Check accessory delay relay. See DELAYED ACCESSORY RELAY under COMPONENT TESTS. If accessory delay relay is okay, go to next step. If accessory delay relay does not test as specified, replace accessory delay relay. Clear DTCs and retest system operation.
- Check Light Blue/Red Wire For Open - Disconnect 18-pin GEM/CTM connector C224 (located behind center of instrument panel). Using an ohmmeter, check resistance in Light Blue/Red wire between accessory delay relay connector terminal No. 85 and 18-pin GEM/CTM connector C224 terminal No. 17. See Fig 1 and Fig 2. If resistance is less than 5 ohms, replace GEM/CTM. Clear DTCs and retest system operation. If resistance is 5 ohms or more, repair open in Light Blue/Red wire. Clear DTCs and retest system operation.
- Check Accessory Delay Relay - Check accessory delay relay. See DELAYED ACCESSORY RELAY under COMPONENT TESTS. If accessory delay relay is okay, go to next step. If accessory delay relay does not test as specified, replace accessory delay relay. Clear DTCs and retest system operation.
- Check Light Blue/Red Wire For Short To Power - Disconnect 18-pin GEM/CTM connector C224 (located behind center of instrument panel). Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and delayed accessory relay connector terminal No. 85 (Light Blue/Red wire). See Fig 1. If any voltage is present, repair short to power in Light Blue/Red wire. Clear DTCs and retest system operation. If no voltage is present, replace GEM/CTM. Clear DTCs and retest system operation.
- Check Fuse - Remove maxi-fuse No. 4 (20-amp) from engine compartment fuse box. If fuse is okay, go to next step. If fuse is blown, replace fuse. Clear DTCs and retest system operation. If fuse fails again, repair short to ground in Light Green/Orange wire. Clear DTCs and retest system operation.
- Check Red/Light Blue Wire For Voltage - Remove accessory delay relay (located under right side of instrument panel, behind glove box). Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 87 (Red/Light Blue wire). See Fig 1. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair Red/Light Blue wire. Clear DTCs and retest system operation.
- Check Accessory Delay Relay - Check accessory delay relay. See DELAYED ACCESSORY RELAY under COMPONENT TESTS. If accessory delay relay is okay, repair Light Blue/Black wire. Clear DTCs and retest system operation. If accessory delay relay does not test as specified, replace accessory delay relay. Clear DTCs and retest system operation.
