1. With the scan tool, observe the Up/Down Sensor and Left/Right Sensor parameters in the appropriate door module Data list.
2. Use the mirror adjustment switches to move the inoperative mirror to the limits of travel in both the vertical and horizontal directions.

Does the scan tool indicate both the Up/Down and Left/Right sensor parameter values change and are within the specified range?

0.25-5.5 V

Go to Step 9

Go to Step 5

1. Turn the ignition OFF.
2. Disconnect the C5 harness connector of the door module associated with the inoperative mirror.
3. Turn ON the ignition, with the engine OFF.
4. Measure the voltage of the 5-volt reference circuit at the door module pin.

Is the voltage indicated within the specified range?

4.25-5.5 V

Go to Step 6

Go to Step 11

With the scan tool, observe the Up/Down Sensor and Left/Right Sensor parameters in the appropriate door module Data list.

Is the voltage indicated within the specified range for both sensors?

4.25-5.5 V

Go to Step 7

Go to Step 11

1. Install a 3-amp fused jumper wire between the mirror sensor return circuit and the horizontal sensor signal circuit at the door module pins.
2. With the scan tool, observe the Left/Right Sensor parameter.
3. Install the 3-amp fused jumper wire between the mirror sensor return circuit and the vertical sensor signal circuit at the door module pins.
4. With the scan tool, observe the Up/Down Sensor parameter.

Did the scan tool indicate the voltage for each sensor was within the specified range?

0-0.5 V

Go to Step 8

Go to Step 11

Inspect for poor connections at the C5 harness connector of the door module associated with the inoperative mirror. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
