Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Module-Memory Mirror: Operation
The memory mirror module receives input from the door lock switches and sends that message to the cluster for door lock operation (vehicles equipped with memory system only). It also controls the mirror adjustment by receiving input from the mirror switch on the door trim panel. Sensors in the mirrors act as inputs to the memory mirror module in order to position the mirrors to presets by the driver(s). The power supply to the mirrors is supplied by the mirror memory modules. On vehicles equipped with a memory system, the front door ajar switches are inputs to the memory mirror module. The modules use this information for door lock inhibit etc.
A memory setting is saved by pressing the "set" button, then pressing either the memory "1" or "2" button within 5 seconds of pressing the "set" button.
A memory setting is recalled by pressing either the memory "1" or "2" button, or by pressing the unlock button on a "linked" Remote Keyless Entry (RKE) transmitter.
For driver safety, memorized settings can not be recalled if the transmission is in a position other than Park or the seat belt is latched.
Both driver and passenger modules provide active and stored Diagnostic Trouble Codes (DTC's) to aid in diagnosis.
Both modules are identical in appearance with the exception of an extra ground wire on the driver side memory mirror module.
