Passenger Mirror Horizontal Sensor Out Of Range Low
NOTE:
After making any repairs, perform MEMORY SYSTEMS VERIFICATION TEST
under VERIFICATION TESTS.
- Turn ignition off. Disconnect Memory Heated Seat/Mirror Module (MHSMM) connector C1. Turn ignition on. Measure voltage on MHSMM connector C1 terminal No. 19, passenger mirror horizontal position signal circuit (Dark Green/Red wire). See Figure . If voltage is 4.5-5.0 volts, replace MHSMM. If voltage is not 4.5-5.0 volts, leave MHSMM connector C1 disconnected, and go to next step.
- Turn ignition off. Disconnect passenger mirror connector. Measure resistance of passenger mirror horizontal position signal circuit (Dark Green/Red wire) between passenger mirror connector terminal No. 9 and MHSMM connector C1 terminal No. 19. See Figure and Figure . If resistance is less than 5 ohms, leave connectors disconnected, and go to next step. If resistance is 5 ohms or more, repair open in Dark Green/Red wire.
- Measure resistance between ground and passenger mirror connector terminal No. 9, passenger mirror horizontal position signal circuit (Dark Green/Red wire). If resistance is less than 100 ohms, repair short to ground in Dark Green/Red wire. If resistance is 100 ohms or more, leave passenger mirror connector disconnected, and go to next step.
- Ensure MHSMM connector is properly connected. Turn ignition on. Measure voltage on passenger mirror connector terminal No. 6, passenger mirror 5-volt supply circuit (Gray/White wire). If voltage is 4.5-5.0 volts, replace passenger mirror. If voltage is not 5.5-5.0 volts, leave passenger mirror connector disconnected, and go to next step.
- Turn ignition off. Disconnect MHSMM connector C2. Measure resistance of passenger mirror 5-volt supply circuit (Gray/White wire) between passenger mirror connector terminal 6 and MHSMM connector C2 terminal No. 8. If resistance is less than 5 ohms, replace MHSMM. If resistance is 5 ohms or more, repair open in Gray/White wire.
