Go to Step 2

Go to Diagnostic System Check - Door Systems

Verify that the Power Mirrors -- Memory Recall Position Inaccurate complaint is present by performing the following steps.

1. Turn ON the ignition, with the engine OFF.
2. Adjust both outside rearview mirrors to your preference.
3. With the memory switch, set the personalization recall to your adjustments.
4. Adjust both outside rearview mirrors to an extreme position.
5. Press the memory button that was previously programmed.

Did both outside rearview mirrors move back to the programmed setting?

1. With the scan tool, navigate to the Driver Door Module, Data list.
2. With the scan tool, observe the appropriate Vertical sensor and Horizontal sensor Position parameters.
3. With the mirror adjustment switches, move the inoperative mirror to the limits of travel in both the vertical and horizontal directions.

Does the scan tool indicate the Vertical and Horizontal Position parameter values change and are within the specified range?

0.5-4.75 V

Go to Step 9

Go to Step 5

1. Turn OFF the ignition.
2. Disconnect the harness connector of the inoperative mirror from the inoperative door module.
3. Make sure that the other harness connectors to the door module remain connected.
4. Turn ON the ignition, with the engine OFF.
5. Measure the voltage of the 5-volt mirror sensor reference circuit at the door module pin.

Is the voltage indicated within the specified range?

4.5-5.5 V

Go to Step 6

Go to Step 11

6

With a scan tool, observe the appropriate Vertical Sensor and Horizontal Sensor Position parameters in the driver door module, data list.

Does the scan tool indicate the Vertical and Horizontal Position parameter values are within the specified range?

4.5-5.5 V

Go to Step 7

Go to Step 11

1. Install a 3-amp fused jumper wire between the mirror sensor ground circuit and the horizontal sensor signal circuit at the door module pins.
2. With the scan tool, observe the Horizontal Sensor Position parameter.
3. Install the 3-amp fused jumper wire between the mirror sensor ground circuit and the vertical sensor signal circuit at the door module pins.
4. With the scan tool, observe the Vertical Sensor Position parameter.

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

0-0.5 V

Go to Step 8

Go to Step 11

Inspect for poor connections at the harness connector of the inoperative outside rear view mirror. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.
