POWER MIRROR CONTROL SYSTEM Wireless Transmitter Memory Function does not Operate

DESCRIPTION

The key ID can be registered to be linked with each of the M1, M2 and M3 seat memory switches. The key ID registration procedure should be performed while the electrical key transmitter is in the vehicle, the power switch is on (IG), and the driver door is closed. When the registration is completed, the buzzer will sound as an answerback.

      Turn the power switch on (IG).

   2. Using the outer mirror switch assembly, turn the mirror surface to the fully left position.

   3. Press the M1 switch while the SET switch is being pressed.

   4. Check that the buzzer sound 0.5 seconds and the mirror surface position is memorized.

   5. Using the outer mirror assembly, turn the mirror surface to the fully right position.

   6. Press the M1 switch.

   7. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the recorded fully left position.

4. READ VALUE USING INTELLIGENT TESTER (DOOR COURTESY SWITCH)

   
   

   1. Connect the intelligent tester to the DLC3.

   2. Turn the power switch on.

   3. Turn the intelligent tester on.

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

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

      Body

      OK
      ON and OFF appear on the screen.

   
   

   NG

   GO TO LIGHTING SYSTEM (Door Courtesy Switch Circuit) Click here

5. PERFORM TRANSMITTER KEY RECOGNITION CODE REGISTRATION

   
   

   1. With the power switch on (IG) and the driver side door closed, press and hold the M1, M2 or M3 switch. The main body ECU (multiplex network body ECU) will enter transmitter key recognition code registration mode to allow a key to be linked to mirror surface memory position.

      Tech Tips

      If the memory switch is released before entering registration mode, the memory switch will not enter registration mode.

   2. When the manual door lock switch is pressed, check that the buzzer of the position control ECU and switch assembly sounds once (0.5 seconds).

      OK
      The buzzer sounds when the registration is completed.

6. PERFORM MEMORY DELETION

   
   

   1. Enter the following menus: Body / Body / Data List.

   2. After performing any of the following procedures to cut the link between the key and switch, check that the Data List for the applicable key changes to NONE.

   3. With the power switch on (IG) and the driver side door closed, press and hold the SET switch. The main body ECU (multiplex network body ECU) will enter transmitter key recognition code deletion mode.

      Tech Tips

      If the memory switch is released before entering deletion mode, the memory switch will not enter deletion mode.

   4. When the manual door lock switch is pressed, check that the buzzer of the position control ECU and switch assembly sounds twice (0.1 seconds each time).
