POWER MIRROR CONTROL SYSTEM Power Retractable Mirrors do not Operate with Power Retract Mirror Switch

SYSTEM DESCRIPTION

This circuit detects the conditions of the mirror retract switch.

The outer mirror switch sends information about the operating condition of the mirror retract switch (switch input signals) through the CAN communication line. Then the switch input signals are sent to the front door ECU LH and RH.

2. READ VALUE USING INTELLIGENT TESTER (MIRROR RETRACT SWITCH)

   
   

   1. Check the Data List for proper functioning of the mirror retract switch.

      D-SEAT SW

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Mirror Close Switch	Mirror retract switch signal / ON or OFF	ON: Mirror retract switch is ON (retracting) OFF: Mirror retract switch is OFF	-
      Mirror Open Switch	Mirror retract switch signal / ON or OFF	ON: Mirror retract switch is ON (returning) OFF: Mirror retract switch is OFF	-

      OK
      On tester screen, each item changes between ON and OFF according to above chart.

   1. 

      for LHD:

      
      

      1. For each mirror position: Disconnect the battery, set the mirror position by hand, connect the battery, and check the retractable mirror's movement.

         Note

         
         

         • Disconnect and reconnect the battery once between each mirror position check.

         • Do not apply battery voltage when moving the mirror by hand into each mirror position.

         OK
