DTC TEST INDEX
Scheme 1
Scheme 2
- Check Window Operation Check operation of power windows. If power windows do not operate, go to next step. If power windows operate, go to step 5).
- Check Signal From GEM Turn ignition off. Remove accessory delay relay (located in fuse junction panel). Using New Generation Star (NGS) tester, enter active command menu. Select ACCY RLY, and trigger relay on. Using a ohmmeter connected to ground, measure resistance between delay relay socket terminal No. 85 and ground. (Scheme 1) If resistance is less than 5 ohms, go to step 4). If resistance is greater than 5 ohms, go to next step. (Scheme 1): Identifying Accessory Delay & One-Touch Down Relay Terminals (Scheme 2): Identifying Fuse Junction Panel Connector C1 Terminals
- Check For Open In Fuse Panel Disconnect fuse junction panel connector C1 from GEM. (Scheme 2) Measure resistance between delay relay terminal No. 85 and fuse junction panel connector C1, terminal No. 17. If resistance is less than 5 ohms, replace GEM. If resistance is greater than 5 ohms, go to step 5).
- Check For Open Circuit Remove battery saver relay from fuse junction panel connector. Measure resistance between battery saver relay socket terminal No. 3 and delay relay socket terminal No. 86. If resistance is less than 5 ohms, replace accessory delay relay. If resistance is greater 5 ohms, replace fuse junction panel.
- Check For Short In Fuse Panel Disconnect GEM from fuse junction panel. Measure resistance between delay relay socket terminal No. 86 and fuse junction panel connector C1, terminal No. 3. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, replace fuse junction panel.
- Check For Short In Relay Turn ignition off. Open driver's door. Remove accessory delay relay from fuse junction panel. Measure resistance between ground and delay relay socket terminal No. 85. If resistance is less than 10 k/ohms, go to next step. If resistance is greater than 10 k/ohms, replace accessory delay relay.
- Check For Short In GEM Disconnect fuse panel connector C1. (Scheme 2) Measure resistance between ground and delay relay socket terminal No. 85. If resistance is less than 10 k/ohms, replace fuse junction panel. If resistance is greater than 10 k/ohms, replace GEM.
