2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?

Signal Circuit Inspection

1. Ignition "ON" and Engine "OFF"
2. Disconnect power window main switch module connector.
3. Measure voltage between "11" power window main switch module harness connector and chassis ground.
A. Specification : Approx. 1 - 4V when power mirror is moved.




4. Is the measured voltage within specification?
YES
1) Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.
Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Check the horizontal sensor wire harness for an open or a short circuit.
If wire harness is OK, replace LH outside mirror (horizontal sensor) and then go to "Verification of Vehicle Repair" procedure.
