INSPECTION AND REPAIR
Switch side
D-19
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.
RTW48AMF000601
MV, MH, b, and e terminals have internal connections (circuitry).
4-point switch (Will not operate at intermediate positions.)
Harness side
D-19
2. Harness Side Connector Circuit
Remove the connector No.
D-19 of the mirror control
switch and check voltage and continuity of the harness side
connector.
When 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.

When there is no continuity at either one of the circuit
No, 5, 7, 8, or 10, the motor in the mirror of the circuit or
the circuit itself is defective.
