Front Passenger Side Power Mirror Cannot Be Adjusted With Power Mirror Switch

MIRROR (EXT): POWER MIRROR CONTROL SYSTEM: Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

Front Passenger Side Power Mirror cannot be Adjusted with Power Mirror Switch

SYSTEM DESCRIPTION

The circuit detects the conditions of the outer mirror switch.
The outer mirror switch sends information about the operating condition of the mirror switch (switch input signals) through the CAN communication line. Then the switch input signals are sent to the outer mirror control ECU. Mirror adjustment is controlled by the outer mirror control ECU.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC
(a) Use the Techstream to check if the CAN communication system is functioning normally. Diagnosis System

Result





B -- GO TO CAN COMMUNICATION SYSTEM
A -- Continue to next step.
2. READ VALUE USING TECHSTREAM (OUTER MIRROR SWITCH)
(a) Check the Data List for proper functioning of the outer mirror switch Scan Tool Testing and Procedures.

Main Body





OK:
On the Techstream screen, each item changes between ON and OFF according to above chart.
NG -- INSPECT OUTER MIRROR SWITCH ASSEMBLY
OK -- Continue to next step.
3. PERFORM ACTIVE TEST USING TECHSTREAM (POWER MIRROR CONTROL FUNCTION)
(a) Select the Active Test, use the Techstream to generate a control command, and then check the power mirror control function Scan Tool Testing and Procedures.

Mirror





Result





B -- REPLACE OUTER MIRROR CONTROL ECU
A -- Continue to next step.
4. INSPECT OUTER REAR VIEW MIRROR ASSEMBLY RH





(a) Remove the mirror RH Removal.
(b) Apply battery voltage and check the operation of the power mirror.
OK:






NG -- REPLACE OUTER REAR VIEW MIRROR ASSEMBLY RH
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (OUTER REAR VIEW MIRROR RH - OUTER MIRROR CONTROL ECU)





(a) Disconnect the I18 ECU connector.
(b) Disconnect the I7 mirror connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE OUTER MIRROR CONTROL ECU
6. INSPECT OUTER MIRROR SWITCH ASSEMBLY





(a) Remove the outer mirror switch Removal.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPLACE OUTER MIRROR SWITCH ASSEMBLY
OK -- Continue to next step.
7. CHECK HARNESS AND CONNECTOR (OUTER MIRROR SWITCH - MAIN BODY ECU)





(a) Disconnect the E1 ECU connector.
(b) Disconnect the G1 switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE MAIN BODY ECU (COWL SIDE JUNCTION BLOCK LH)
