INSPECTION AND REPAIR





Switch side
D19


Door Mirror Control Switch
1. Switch side Connector Circuit
Check continuity between the switch connector terminals while operating the door mirror control switch as shown in
the following table.





RTW 48AMF000601
MV, MH, b, and e terminals have internal connections (circuitry).
4-point switch (W ill not operate at intermediate positions.)





Harness side
D19


2. Harness Side Connector Circuit
Remove the connector No.
D19 of the mirror control
switch and check voltage and continuity of the harness side
connector.
• W hen there is no continuity at the terminal No. 2, 3, 9
and 10, it is considered that the circuit with terminal No.
7 (W /B) is defective.
