Driver Mirror Horizontal Sensor Out Of Range High

1. Turn ignition off. Disconnect Memory Heated Seat/Mirror Module (MHSMM) harness connector C1. Turn ignition on. Measure voltage at terminal No. 20 (Dark Blue/Yellow wire) at MHSMM harness connector C1. See Figure . If voltage is greater than 4.5 volts, go to next step. If voltage is 4.5 volts or less, replace MHSMM.
2. Disconnect driver's mirror harness connector. Measure voltage at terminal No. 9 (Dark Blue/Yellow wire) at driver's mirror harness connector. See Fig 1 . If any voltage exists, repair short to voltage in Dark Blue/Yellow wire between MHSMM and driver's mirror. If no voltage exists, replace driver's mirror.
