Test B: Single Power Mirror Inoperative
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.
- Turn ignition switch to LOCK position. Remove appropriate door trim panel. See DOOR TRIM PANEL under REMOVAL & INSTALLATION in POWER DOOR LOCKS & TRUNK RELEASE article (If driver's door trim panel is removed, leave power mirror control switch connected). Disconnect power mirror 5-pin harness connector C560 for driver's side or C622 for passenger's side. Power mirror connectors C560 or C622 are located under door trim panel. See Figure. Select appropriate inoperative power mirror on power mirror control switch. While operating power mirror control switch to down and right positions, measure voltage between ground and power mirror harness connector terminal No. 2 (Yellow wire for driver's side) or (White wire for passenger's side). See Fig 1. See WIRING DIAGRAMS . If voltage is 10 volts or less in either position, go to next step. If voltage is greater than 10 volts in both positions, go to step 3. After repair, test system for normal operation.
- Ensure ignition switch is in LOCK position. Disconnect power mirror control switch 8-pin harness connector C521. Power mirror harness connector C521 is located under driver's door trim panel. See Figure. Measure resistance between power mirror control switch harness connector C521 terminal No. 6 (Yellow wire) and inoperative power mirror harness connector C560 terminal No. 2 (Yellow wire on driver's side) or C622 (White wire on passenger's side). See Figure and Fig 1 . See WIRING DIAGRAMS . If resistance is 5 ohms or less, replace power mirror control switch. See POWER MIRROR CONTROL SWITCH under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair open circuit in appropriate wire between appropriate power mirror and power mirror control switch. After repair, clear DTC and test system for normal operation.
- While operating power mirror control switch to up position, measure voltage between ground and inoperative power mirror harness connector C560 terminal No. 1 (Dark Blue wire on driver's side) or connector C622 terminal No. 1 (Violet wire on passenger's side). See Fig 1. If voltage is 10 volts or less, go to next step for driver's power mirror, or step 5 for passenger's power mirror. If voltage is greater than 10 volts, go to step 6.
- Disconnect power mirror control switch 8-pin harness connector C521. Power mirror harness connector C521 is located under driver's door trim panel. See Figure. Measure resistance between power mirror control switch harness connector C521 terminal No. 7 and driver's power mirror harness connector C560 terminal No. 1 (Dark Blue/Yellow wire). See Figure and Fig 1 . See WIRING DIAGRAMS . If resistance is 5 ohms or less, replace power mirror control switch. See POWER MIRROR CONTROL SWITCH under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair open circuit in Dark Blue/Yellow wire between driver's power mirror and power mirror control switch. After repair, clear DTC and test system for normal operation.
- Disconnect power mirror control switch 8-pin harness connector C521. Power mirror harness connector C521is located under driver's door trim panel. See Figure. Measure resistance between power mirror control switch harness connector C521 terminal No. 8 and passenger's power mirror harness connector C622 terminal No. 1 (Violet wire). See Figure and Fig 1 . See WIRING DIAGRAMS . If resistance is 5 ohms or less, replace power mirror control switch. See POWER MIRROR CONTROL SWITCH under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair open circuit in Violet wire between passenger's power mirror and power mirror control switch. After repair, clear DTC and test system for normal operation.
- While operating power mirror control switch to left position, measure voltage between ground and inoperative power mirror harness connector terminal No. 3 (Red wire for driver's side) or (Dark Green wire for passenger's side). If voltage is 10 volts or less, go to next step for driver's power mirror, or step 8 for passenger's power mirror. See WIRING DIAGRAMS . If voltage is greater than 10 volts, replace appropriate power mirror motor. See POWER MIRROR GLASS & MOTOR under REMOVAL & INSTALLATION. After repair, test system for normal operation.
- Disconnect power mirror control switch 8-pin harness connector C521. Power mirror harness connector C521is located under driver's door trim panel. See Figure. Measure resistance between power mirror control switch harness connector C521 terminal No. 4 and driver's power mirror harness connector C560 terminal No. 3 (Red wire). See Figure and Fig 1 . See WIRING DIAGRAMS . If resistance is 5 ohms or less, replace power mirror control switch. See POWER MIRROR CONTROL SWITCH under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair open circuit in Red wire between driver's power mirror and power mirror control switch. After repair, clear DTC and test system for normal operation.
- Disconnect power mirror control switch 8-pin harness connector C521. Power mirror harness connector C521is located under driver's door trim panel. See Figure. Measure resistance between power mirror control switch harness connector C521 terminal No. 8 and passenger's power mirror harness connector C622 terminal No. 3 (Dark Green wire). See Figure and Fig 1 . See WIRING DIAGRAMS . If resistance is 5 ohms or less, replace power mirror control switch. See POWER MIRROR CONTROL SWITCH under REMOVAL & INSTALLATION. If resistance is greater than 5 ohms, repair open circuit in Dark Green wire between driver's power mirror and power mirror control switch. After repair, clear DTC and test system for normal operation.
