Test E: Delayed Accessory Inoperative

NOTE: If DTCs B1314 or B1315 are present, repair these codes before proceeding. See GENERIC ELECTRONIC MODULE DTC INDEX  table under SELF-DIAGNOSTIC SYSTEM.
NOTE: After making any repair, repeat Generic Electronic Module (GEM) self-test using WDS or NGS tester.
NOTE: Perform all voltage and resistance tests using a Digital Volt-Ohm Meter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
  1. Turn ignition switch to LOCK position. Connect Worldwide Diagnostic System (WDS) tester or New Generation Star (NGS) tester to Data Link Connector (DLC), located below instrument panel. See Figure. Turn ignition switch to RUN position. Using WDS or NGS tester, perform Generic Electronic Module (GEM) self-test. If no DTC is retrieved, go to next step. If DTC B1302 or 1304 is retrieved, go to step  4.
  2. Turn ignition switch to LOCK position. Remove fuse No. 10 (30-amp) from Central Junction Box (CJB). See Figure. Turn ignition switch to RUN position. Measure voltage between ground and input side of fuse No. 10. See WIRING DIAGRAMS . If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair power supply to CJB. After repair, test system for normal operation.
  3. Turn ignition switch to LOCK position. Install fuse No. 10 back in CJB. See Figure. Turn ignition switch to RUN position. Using WDS or NGS tester, select GEM active command ONE TOUCH WINDOW & ACCY DELAY. Trigger ACCY RLY to ON position. Operate power windows. If power windows do not operate, go to next step. If power windows operate, go to step  9.
  4. Turn ignition switch to LOCK position. Remove delayed accessory relay from connector C2050 located on CJB. See Figure. Perform delayed accessory relay component test. See RELAYS  under COMPONENT TESTS. If relay is okay, go to next step. If relay is faulty, replace delayed accessory relay. After repair, test system for normal operation.
  5. Turn ignition switch to RUN position. Measure voltage between ground and delayed accessory relay connector C2050 terminal No. 86. Also measure voltage between delayed accessory relay connector C2050 terminal No. 30. See Figure. See WIRING DIAGRAMS . If voltages are greater than 10 volts, go to next step. If any voltage is less than 10 volts, repair open circuit in CJB as necessary. After repair, test system for normal operation.
  6. Ensure ignition switch is on RUN position. Measure voltage between ground and delayed accessory relay connector C2050 terminal No. 85. See Figure. If any voltage exists, go to next step. If no voltage exists, go to step  8.
  7. Turn ignition switch to LOCK position. Disconnect GEM 26-pin harness connector C201d. See Figure. GEM connector is located in Central Junction Box (CJB). See Figure. Turn ignition switch to RUN position. Measure voltage between ground and delayed accessory relay connector C2050 terminal No. 85. See WIRING DIAGRAMS . If no voltage exists, go to step  9. If any voltage exists, repair short circuit to power in CJB as necessary. After repair, test system for normal operation.
  8. Turn ignition switch to OFF position. Disconnect One-Touch Down (OTD) relay from connector C2051 located on Central Junction Box (CJB). See Figure. Connect a fused jumper wirebetween delayed accessory relay connector C2050 terminals No. 30 and 87. See Figure. Turn ignition switch to RUN position. Measure voltage between ground and OTD relay connector C2051 terminal No. 2. See Figure. See WIRING DIAGRAMS . If voltage is greater than 10 volts, go to next step. If voltage is less than 10 volts, repair open circuit in CJB as necessary.After repair, test system for normal operation.
  9. Turn ignition switch to LOCK position. Check all GEM harness connectors terminals for corroded or pushed-out pins. If connector or terminals are faulty, repair or replace as necessary. If connector and terminals are okay, reconnect all GEM harness connectors. Ensure all other system connectors are properly seated. Operate system and verify if concern is still present. If concern still present, install a new GEM. See GENERIC ELECTRONIC MODULE  under REMOVAL & INSTALLATION. If concern is not present, system is operating properly. Clear DTCs and check system for normal operation.
