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

SYSTEM DESCRIPTION

The main body ECU (multiplex network body ECU) receives the outer mirror retract switch signal from the multiplex network master switch assembly via LIN communication. The main body ECU then sends the mirror retract/return signal to each outer mirror control ECU via CAN communication. Based on the signal, each outer mirror control ECU retracts or returns the outer rear view mirror assembly.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK CAN COMMUNICATION SYSTEM

   
   

   1. Use the intelligent tester to check if the CAN communication system is functioning normally Click here.

      OK
      CAN communication DTC is not output.

   
   

   NG

   GO TO CAN COMMUNICATION SYSTEM Click here

   OK

2. CHECK LIN COMMUNICATION SYSTEM

   
   

   1. Use the intelligent tester to check if the LIN communication system is functioning normally Click here.

      OK
      LIN communication DTC is not output.

   
   

   NG

   GO TO LIN COMMUNICATION SYSTEM Click here

   OK

3. READ VALUE USING INTELLIGENT TESTER (OUTER MIRROR RETRACT SWITCH)

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the power switch on (IG).

   3. Turn the intelligent tester on.

   4. Enter the following menus: Body / Master Switch / Data List.

   5. Read the Data List according to the display on the intelligent tester.

      Master Switch

      Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
      Outer Mirror Fold SW	Mirror retract switch signal / ON or OFF	ON: Retract switch in retract position OFF: Retract switch in driving position	-

      OK
      On the intelligent tester screen, ON or OFF is displayed for each item according to the above.

   
   

   NG

   REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY Click here

   OK

4. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (MIRROR RETRACT FUNCTION)

   
   

   1. Enter the following menus: Body / Mirror L or Mirror R / Active Test.

   2. Perform the Active Test according to the display on the intelligent tester.

      Mirror L / Mirror R

      Tester Display	Test Part	Control Range	Diagnostic Note
      Mirror Fold/Return	Mirror retract operation	ON / OFF	-

6. CHECK POWER RETRACT MIRROR FUNCTION

   
   

   1. Check power retract mirror function (manual function) Click here.

      OK
      Power retract mirror function (manual function) is normal.

   
   

   NG

   REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY Click here

   OK

   END (MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) WAS DEFECTIVE)

7. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH

   
   

   1. 

      Remove the outer rear view mirror assembly RH Click here.

   2. When checking each mirror position, set the mirror position by hand. Apply auxiliary battery voltage and check the mirror movement.

      Note

      
      

      • Disconnect and reconnect the auxiliary battery for each mirror position check.

      • The mirror position cannot be changed manually when the auxiliary battery is connected. To change the mirror position manually, the auxiliary battery must be disconnected first.

      OK
