Test H: Passenger's Window Inoperative From Driver's Control Switch

  1. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). Using NGS tester, perform Driver's Door Module (DDM) self-test. If DTC B1420 is retrieved, go to next step. If other DDM DTCs are retrieved, see DRIVER'S DOOR MODULE DTC INDEX  table under SELF-DIAGNOSTIC SYSTEM. If no DDM DTCs are retrieved, go to step  4 .
  2. Turn ignition switch to LOCK position. Remove driver's control switch. Perform DRIVER'S CONTROL SWITCH  test under COMPONENT TESTS. If switch is okay, go to next step. If switch is faulty, replace driver's control switch and retest system operation.
  3. Disconnect DDM 26-pin harness connector C501d. Turn ignition switch to RUN position. Measure voltage between driver's control switch 16-pin harness connector C504 terminal No. 3 (Yellow/Violet wire) and ground. See Figure . Measure voltage between driver's control switch 16-pin harness connector C504 terminal No. 2 (Yellow/Black wire) and ground. If any voltage is greater than 10 volts, repair short to power in appropriate wire and retest system operation. If voltages are less than 10 volts, replace DDM and retest system operation.
  4. Turn ignition switch to LOCK position. Ensure NGS tester is properly connected. Turn ignition switch to RUN position. Using NGS tester, monitor DDM PIDS P_UP_SW and P_DM_SW while operating passenger's window with driver's control switch in UP and DOWN positions. If DDM PIDS P_UP_SW and P_DN_SW agree with driver's control switch positions, replace DDM and retest system operation. If DDM PIDS P_UP_SW and P_DN_SW do not agree with driver's control switch positions, go to next step.
  5. Turn ignition switch to LOCK position. Remove driver's control switch. Perform DRIVER'S CONTROL SWITCH  test under COMPONENT TESTS. If switch is okay, go to next step. If switch is faulty, replace driver's control switch and retest system operation.
  6. Disconnect DDM 26-pin harness connector C501d. Measure resistance in Yellow/Violet wire between driver's control switch 16-pin harness connector C504 terminal No. 3 and DDM 26-pin harness connector C501d terminal No. 3. See Figure . Measure resistance in Yellow/Black wire between driver's control switch 16-pin harness connector C504 terminal No. 2 and DDM 26-pin harness connector C501d terminal No. 2. If resistances are less than 5 ohms, go to next step. If any resistance is greater than 5 ohms, repair open in appropriate wire and retest system operation.
  7. Measure resistance between driver's control switch 16-pin harness connector C504 terminal No. 3 (Yellow/Violet wire) and ground. Measure resistance between driver's control switch 16-pin harness connector C504 terminal No. 2 (Yellow/Black wire) and ground. If resistances are greater than 10 k/ohms, replace DDM and retest system operation. If any resistance is less than 10 k/ohms, repair short to ground in appropriate wire(s) and retest system operation.
