POWER MIRROR CONTROL SYSTEM Power Mirrors do not Return to Memorized Position

SYSTEM DESCRIPTION

When the seat memory M1, M2 or M3 switch is pressed, the front power seat switch (for driver side) memory's driver and passenger seat mirror position signal is sent through the CAN communication line to the front door ECU LH and RH. The front door ECU LH and RH then activate the mirror control motors to move the mirrors to the previously recorded positions.

   READ VALUE USING INTELLIGENT TESTER (MIRROR POSITION SENSOR)

   
   

   1. Check the Data List for proper functioning of the mirror position sensor.

      Table 2. Driver Door

      Tester Display	Measurement Item/Display	Normal Condition	Diagnostic Note
      Mirror Vertical Sensor voltage	Mirror vertical sensor voltage / MIN: 0 V, MAX: 5 V	Within range from 0 to 5 V	-
      Mirror Horizontal Sensor Voltage	Mirror horizontal sensor voltage / MIN: 0 V, MAX: 5 V	Within range from 0 to 5 V	-

      Table 3. Passenger Door

      Tester Display	Measurement Item/Display	Normal Condition	Diagnostic Note
      Mirror Vertical Sensor voltage	Mirror vertical sensor voltage / MIN: 0 V, MAX: 5 V	Within range from 0 to 5 V	-
      Mirror Horizontal Sensor Voltage	Mirror horizontal sensor voltage / MIN: 0 V, MAX: 5 V	Within range from 0 to 5 V	-

      OK
      The value is changed by manual operation.
