TEST A: ALL POWER WINDOWS ARE INOPERATIVE
NOTE:This test is associated with DTCs B1302, B1304, B1313, B1315 and B1342.

Check Ignition States - Turn ignition off. Using NGS tester, access GEM PID IGN_GEM. Monitor GEM PID IGN_GEM PID while rotating ignition switch through START, RUN, OFF and ACC positions. If GEM PID IGN_GEM values agree with ignition switch positions, go to next step. If GEM PID IGN_GEM values do not agree with ignition switch positions, repair or replace ignition switch and retest system operation.
Retrieve DTCs - Using NGS tester, retrieve and record continuous DTCs. Using NGS tester, perform GEM On-Demand Self-Test. If no DTCs are retrieved, go to next step. If DTCs B1313 and/or B1315 are retrieved, go to next step. If DTCs B1302 and/or B1304 are retrieved, go to step 4). If DTC B1342 is retrieved, replace GEM. Clear DTCs and retest operation.
Check Battery Saver Relay Coil Circuit - Turn ignition switch to RUN position. Using NGS tester, access GEM PID BATSAV. Monitor GEM PID BATSAV while triggering GEM active command mode BATT SAVR on and off. If GEM PID BATSAV value agrees 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 Accessory Delay Relay Coil Circuit - Using NGS tester, access GEM PID ACCDLY. Monitor GEM PID ACCDLY while triggering GEM active command mode 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 ACCDLY PID values agree with command mode and vehicle is 2-door model, go to step 11). If ACCDLY PID values agree with command mode and vehicle is 4-door model, go to step 10).
Check Voltage To Accessory Delay Relay Coil - Turn ignition off. Remove accessory delay relay (located in relay module, behind center of instrument panel). Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 86 (Light Green/Orange wire). See Fig. 7. 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 ACCESSORY DELAY 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 connector C283 (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 connector C283 terminal No. 17. See Fig. 7 and Fig. 8. If resistance is less than 5 ohms, replace GEM. 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 ACCESSORY DELAY 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 connector C283 (located behind center of instrument panel). Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 85 (Light Blue/Red wire). See Fig. 7. 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. Clear DTCs and retest system operation.
Check For Voltage To Driver Door Master Window/Door Lock Control Switch - Turn ignition off. Remove and disconnect driver door master window/door lock control switch connector C501. See POWER WINDOW SWITCH under REMOVAL & INSTALLATION. Turn ignition switch to RUN position. Using NGS tester, access GEM active command mode ACCY RLY. Trigger ACCY RLY on. Using a voltmeter, check voltage between ground and driver door master window/door lock control switch connector C501 terminal No. 19 (Light Blue/Black wire). If voltage is 10 volts or less, go to next step. If voltage is more than 10 volts, go to step 14).
Check Fuse - Turn ignition off. Remove maxi-fuse No. 4 (30-amp) from engine compartment power distribution box. If fuse is okay, go to next step. If fuse is blown, replace fuse and retest system operation. If fuse fails again, repair short to ground in Red/Light Blue wire. Clear DTCs and retest system operation.
Check Voltage To Accessory Delay Relay Switch - Remove accessory delay relay (located in relay module, behind center of instrument panel). Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 87 (Red/Light Blue wire). 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 ACCESSORY DELAY 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.
Check Driver Door Master Window/Door Lock Control Switch Ground Circuit - Turn ignition off. Using an ohmmeter, check resistance between ground and driver door master window/door lock control switch connector C501 terminal No. 13 (Black wire). If resistance is less than 5 ohms, replace driver door master window/door lock control switch. If resistance is 5 ohms or more, repair open in Black wire. Clear DTCs and retest system operation.
