Memory Mirror Module (MMM) Learn Procedure

Memory Mirror Module (MMM) Learn Procedure

The mirror relearn procedure, when initiated, commands the Memory Mirror Module (MMM) to control the driver and then the passenger mirror in the left, right, up and down directions. When commanding the mirrors the MMM also learns the direction of horizontal and vertical position sensor signal circuit feedback voltages. To initiate the relearn procedure, perform the following:

1. With a scan tool, select Memory Mirror Module
2. Select Special Functions
3. Select Output Controls
4. Select Mirror Relearn
5. Then press the Reset button

If the mirror relearn procedure does not control the driver and passenger mirrors as described, there may be another fault in the mirror systems. Refer to Diagnostic System Check - Door Systems to begin the diagnosis of the mirror system.
