Mirror Motor Circuit
MIRROR: POWER MIRROR CONTROL SYSTEM: Mirror Motor Circuit
- Mirror Motor Circuit
DESCRIPTION
This circuit detects the conditions of the mirror master switch and mirror control switch. The operating condition of the mirror switch is input by the driver side junction block ECU, and the input signals are sent to the multiplex network door ECU front LH or RH (driver or front passenger door ECU). Mirror adjustment is controlled by the multiplex network door ECU front LH or RH.
WIRING DIAGRAM
INSEPCTION PROCEDURE
PROCEDURE
1. PERFORM ACTIVE TEST USING TECHSTREAM (MIRROR RETRACT FUNCTION)
(a) Select the Active Test, use the Techstream to generate a control command, and then check the mirror retract function.
Driver Door, Passenger Door
Result
C -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT RH (FRONT PASSENGER DOOR ECU)
B -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT LH (DRIVER DOOR ECU)
A -- Continue to next step.
2. CHECK WIRE HARNESS (MULTIPLEX NETWORK DOOR ECU FRONT LH OR RH - BATTERY AND BODY GROUND)
(a) Disconnect the D23 or P43 ECU connector.
(b) Measure the voltage of the wire harness side connector.
Standard voltage:
Multiplex network door ECU front LH (driver door ECU)
Multiplex network door ECU front RH (front passenger door ECU)
(c) Measure the resistance of the wire harness side connector.
Standard resistance:
Multiplex network door ECU front LH (driver door ECU)
Multiplex network door ECU front RH (front passenger door ECU)
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. INSPECT OUTER MIRROR ACTUATOR ASSEMBLY LH OR RH (RETRACTABLE MIRROR MOTOR)
(a) Disconnect the R14 or R15 mirror connector.
(b) Apply battery voltage and check the operation of the retractable mirror.
NOTICE:
* Disconnect and reconnect the battery once between each mirror position check.
* The mirror position cannot be changed manually when the battery is connected. To change the mirror position manually, the battery must be disconnected first.
OK:
Result
D -- REPLACE OUTER MIRROR ACTUATOR ASSEMBLY RH
C -- REPLACE OUTER MIRROR ACTUATOR ASSEMBLY LH
B -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT RH (FRONT PASSENGER DOOR ECU)
A -- REPLACE MULTIPLEX NETWORK DOOR ECU FRONT LH (DRIVER DOOR ECU)
