1. DESCRIPTION The power mirror control system data and the Diagnostic Trouble Codes (DTCs) can be read through the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the intelligent tester to check for malfunctions and perform repairs.
2. CHECK DLC3 The vehicle uses ISO 15765-4 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format. (Scheme 17): Identifying DLC3 Connector Terminal TERMINAL SPECIFICATION Symbols (Terminals No.) Terminal Description Condition Specified condition SIL (7) - SG (5) Bus "+" line During transmission Pulse generation CG (4) - Body ground Chassis ground Always Below 1 ohms SG (5) - Body ground Signal ground Always Below 1 ohms BAT (16) - Body ground Battery positive Always 11 to 14 V If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector. HINT: Connect the cable of the intelligent tester (with CAN VIM) to the DLC3, turn the ignition switch ON and attempt to use the tester. If the screen displays the message UNABLE TO CONNECT TO VEHICLE, there is a problem either with the vehicle or with the tester. (Scheme 18): Connecting Cable Of Intelligent Tester To DLC3 If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle. If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself. Consult the Service Department listed in the tester's instruction manual.

DATA LIST / ACTIVE TEST

1. READ DATA LIST HINT: Using the intelligent tester's DATA LIST allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the DATA LIST early in troubleshooting is one way to save time. Connect the intelligent tester to the DLC3. Turn the ignition switch ON. Read the DATA LIST.

1. CHECK MEMORY AND REACTIVATION FUNCTION Procedure "A": Turn the ignition switch ON and move the shift lever to the P position. Procedure "B": Check the seat memory (for driver side) M1 switch. Step 1: Using the outer mirror switch, move the mirror as much as possible to the left. Step 2: Press and hold down switches M1 and SET. Check that the buzzer sounds for 0.5 seconds, signaling that the outer mirror position has been recorded. Step 3: Change the position of the outer mirror and then press the M1 switch. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the position in Procedure "B" - step 1. Procedure "C": Check the M2 switch. Step 1: Using the outer mirror switch, move the mirror as much as possible to the right. Step 2: Press and hold down switches M2 and SET. Check that the buzzer sounds for 0.5 seconds, signaling that the outer mirror position has been recorded. Step 3: Change the position of the outer mirror and then press the M2 switch. Check that the buzzer sounds for 0.1 seconds and the outer mirror automatically moves to the position in Procedure "C" - step 1. (Scheme 19): Checking Memory And Reactivation Function Procedure "D": When the outer mirror is in the driving position: Check that switches M1 and M2 cause the outer mirror to move to the recorded outer mirror positions under these conditions: turn the ignition switch OFF, remove the key from the key cylinder, open the driver side door and press M1 or M2 within 30 seconds. Procedure "E": Check that the following procedures will erase the recorded outer mirror positions of switches M1 and M2: press and hold the power seat slide switch; disconnect the cable from the negative (-) battery terminal; and wait for at least 1 minute. Procedure "F": Check that the outer mirror position is not memorized when the M1, M2 and SET switches are pressed and held simultaneously.
2. CHECK ELECTRICALLY-RETRACTABLE DOOR MIRROR (W/ RETRACTABLE MIRROR) Turn the ignition switch to ACC. At each position of the outer mirror body, check the operation when operating the retract switch of the outer mirror. Change the retract switch from the (A) to the (B) position. Check that the right and left mirrors move from the driving position to the retracted position. (Scheme 20): Identifying Outer Mirror Body Switch Position Move one of the mirrors to the forward position by hand. Change the retract switch from the (A) to the (B) position. Check that the mirror moves from the forward position to the retracted position. Check that the other mirror moves from the driving position to the retracted position. (Scheme 21): Identifying Outer Mirror Body Switch Position Move one of the mirrors to the retracted position by hand. Change the retract switch from the (A) to the (B) position. Check that the other mirror moves from the driving position to the retracted position. (Scheme 22): Identifying Outer Mirror Body Switch Position Change the retract switch from the (B) to the (A) position. Check that the right and left mirrors move from the retracted position to the driving position. (Scheme 23): Identifying Outer Mirror Body Switch Position Move one of the mirrors to the driving position by hand. Change the retract switch from the (B) to the (A) position. Check that the other mirror moves from the retracted position to the driving position. (Scheme 24): Identifying Outer Mirror Body Switch Position Check the operation of the outer mirror body in relation to retract switch operations and ignition switch position change. When the mirror body is operating, turn the ignition switch OFF. Check that the mirror operation does not stop and continues until the operation has finished. Repeat the step above. This time, before the mirror operation completes, turn the ignition switch to ACC and press the retract switch. Check that the mirror operates in the opposite direction. Check the operation of the outer mirror body when it is restrained by an obstacle. Step 1: When the mirror body is moving to the retracted or driving position, restrain the mirror body by hand. Check that the mirror body movement stops. Step 2: With the mirror body stopped partway in step 1, push the retract switch. Check that the mirror body moves in the opposite direction it was moving in step 1.
3. CHECK REVERSE-SHIFT-LINKED OPERATION OF MIRRORS Turn the ignition switch ON. Set the mirror master switch to L or R. Check that the mirror faces downward when the shift lever is moved to R. When the shift lever is not on P, or the mirror master switch is in the neutral position (OFF), check that the outer rear view mirror returns to the driving position. (Scheme 25): Identifying Mirror Master Switch
