1. NO: Go to step   3 
2. YES: GO TO NEXT STEP 

1. ACTIVE TEST
   1. Make a judgement of good or bad and find out a malfunctioning part by the active test.

   Standard: 

DOOR ECU 

HINT:

• If the driver's side mirror malfunctions, proceed to OK-A.
• If the passenger's side mirror malfunctions, proceed to OK-B.

1. OK-A: CHECK AND REPLACE MULTIPLEX NETWORK DOOR ECU FRONT LH (See  ELECTRONIC CIRCUIT INSPECTION PROCEDURE  ) 
2. OK-B: CHECK AND REPLACE MULTIPLEX NETWORK DOOR ECU FRONT RH (See  ELECTRONIC CIRCUIT INSPECTION PROCEDURE  ) 
3. NG: Go to step   4 

1. Check that the mirror operates when the battery voltage is applied to the door ECU connector.

HINT:

• If the driver's side mirror malfunctions, proceed to OK-A.
• If the passenger's side mirror malfunctions, proceed to OK-B.

1. OK-A: CHECK AND REPLACE MULTIPLEX NETWORK DOOR ECU FRONT LH (See  ELECTRONIC CIRCUIT INSPECTION PROCEDURE  ) 
2. OK-B: CHECK AND REPLACE MULTIPLEX NETWORK DOOR ECU FRONT RH (See  ELECTRONIC CIRCUIT INSPECTION PROCEDURE  ) 
3. NG: Go to step 4 

1. Check the voltage between each terminal of the door ECU that does not perform the retraction operation.
