Auto Power Retract Mirrors Do Not Operate
MIRROR (EXT): POWER MIRROR CONTROL SYSTEM (w/ Memory): AUTO Power Retract Mirrors do not operate
- AUTO Power Retract Mirrors do not operate
DESCRIPTION
The retractable outer mirror switch sends a voltage signal to the main body ECU (multiplex network body ECU) in accordance with switch operation (switch input signal). The main body ECU (multiplex network body ECU) uses CAN communication to send this information to the outer mirror control ECU assembly, which then controls the mirrors.
When the outer mirror control ECU assembly receives a door lock output signal from the main body ECU (multiplex network body ECU) while the retractable outer mirror switch is in the AUTO position, the outer mirror control ECU assembly operates the retract motors built into the outer rear view mirror assemblies to retract or return the outer rear view mirror assemblies.

INSPECTION PROCEDURE
PROCEDURE
1. CHECK POWER RETRACT MIRROR FUNCTION
(a) Check power retract mirror function Operation Check.
OK:
Power retract mirror function is normal.
NG -- GO TO OTHER FLOW CHART (Retract Mirror do not Operate with Retract Switch) Power Retractable Mirrors Do Not Operate With Power Retract Mirror Switch
OK -- Continue to next step.
2. CHECK CAN COMMUNICATION SYSTEM
(a) Use the Techstream to check if the CAN communication system is functioning normally Diagnosis System.
OK:
CAN communication DTC is not output.
NG -- GO TO CAN COMMUNICATION SYSTEM (DIAGNOSTIC TROUBLE CODE CHART) CAN Communication System
OK -- Continue to next step.
3. CHECK WIRELESS DOOR LOCK CONTROL SYSTEM
(a) Check the wireless door lock control system Operation Check.
OK:
Wireless door lock control system is normal.
NG -- GO TO WIRELESS DOOR LOCK CONTROL SYSTEM (PROBLEM SYMPTOMS TABLE) Problem Symptoms Table
OK -- Continue to next step.
4. CHECK SMART ACCESS SYSTEM WITH PUSH-BUTTON START (ENTRY FUNCTION)
(a) Check the smart access system with push-button start (entry function) Operation Check.
OK:
Smart access system with push-button start (entry function) is normal.
NG -- GO TO SMART ACCESS SYSTEM WITH PUSH-BUTTON START (PROBLEM SYMPTOMS TABLE) Problem Symptoms Table
OK -- Continue to next step.
5. READ VALUE USING TECHSTREAM
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Main Body / Data List.
(e) Read the Data List according to the display on the Techstream.
Main Body
OK:
On the Techstream screen, ON or OFF is displayed for each item according to the table above.
NG -- INSPECT RETRACTABLE OUTER MIRROR SWITCH
OK -- Continue to next step.
6. REPLACE OUTER MIRROR CONTROL ECU ASSEMBLY
(a) Replace the outer mirror control ECU assembly Removal.
NG -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) Removal
OK -- END (OUTER MIRROR CONTROL ECU ASSEMBLY WAS DEFECTIVE) Removal
7. INSPECT RETRACTABLE OUTER MIRROR SWITCH
(a) Remove the retractable outer mirror switch Removal.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPLACE RETRACTABLE OUTER MIRROR SWITCH Removal
OK -- CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - RETRACTABLE OUTER MIRROR SWITCH)
8. CHECK HARNESS AND CONNECTOR (MAIN BODY ECU - RETRACTABLE OUTER MIRROR SWITCH)
(a) Disconnect the H17 connector from the main body ECU (multiplex network body ECU).
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (MAIN BODY ECU - RETRACTABLE OUTER MIRROR SWITCH)
OK -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) Removal
