Test D: One-Touch Down Feature Inoperative

NOTE: After repair, clear DTCs and retest system.
  1. Using New Generation Star (NGS) tester, perform Generic Electronic Module (GEM) self-test. If no DTCs, DTC B1398 or DTC B1400 are present, go to next step. If DTCs B1405 or B1410 are present, go to TEST C: SINGLE WINDOW INOPERATIVE (ALL OTHER WINDOWS OPERATE)  . If DTC B1342 is present, replace GEM. See GENERIC ELECTRONIC MODULE (GEM)  under REMOVAL & INSTALLATION.
  2. Turn ignition switch to RUN position. Using NGS tester, trigger GEM active command ACCY RLY to ON. Observe GEM PID D_PWRLY while triggering GEM active command ONE TOUCH to ON and OFF. If PID value agrees with command mode, go to TEST C: SINGLE WINDOW INOPERATIVE (ALL OTHER WINDOWS OPERATE)  . If PID does not agree with command mode and displays OFFO-G, go to next step. If PID does not agree with command mode and displays ON-B-, go to step  6 .
  3. Turn ignition switch to LOCK position. Check one-touch down relay. See MINI RELAYS  under COMPONENT TESTS. If one-touch down relay is okay, go to next step. If one-touch down relay is faulty, replace relay.
  4. Remove accessory delay relay from central junction box. Measure resistance between accessory delay relay socket terminal No. 87 and one-touch down relay socket terminal No. 85. See Figure . If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, replace central junction box.
  5. Disconnect GEM from central junction box 18-pin connector C267. Measure resistance internal resistance of central junction box between one-touch down relay socket terminal No. 86 and central junction box connector C267 terminal No. 2. See Figure and Figure . Resistance should be less than 5 ohms. Measure resistance between central junction box connector C267 terminal No. 2 (central junction box side) and ground. Resistance should be 10 k/ohms or more. If resistances are as specified, replace GEM. See GENERIC ELECTRONIC MODULE (GEM)  under REMOVAL & INSTALLATION. If resistances are not as specified, replace central junction box.
  6. Turn ignition switch to LOCK position. Check one-touch down relay. See MINI RELAYS  under COMPONENT TESTS. If one-touch down relay is okay, go to next step. If one-touch down relay is faulty, replace relay.
  7. Disconnect GEM from central junction box 18-pin connector C267. Turn ignition switch to RUN position. Measure voltage between one-touch down relay socket terminal No. 86 and ground. See Figure . If voltage is present, replace central junction box. If voltage is not present, replace GEM. See GENERIC ELECTRONIC MODULE (GEM)  under REMOVAL & INSTALLATION.
