Repair the fault point between the left front window switch wire harness connector and
the BCM circuit.

(a) Repair fault points between left front window switch wire harness connector DR10 terminal

No. 20, 19 and 18 corresponding to BCM wire harness connector IP50 terminal No. 39, 19
and 3.

(b) Connect glass lifter switch wire harness connector.

(c) Connect to BCM harness connector IP50,

(d) Connect battery negative cable.

(e) Turn on ignition switch to position "ON".

(f) Operate left front window glass lifter switch.

Confirm whether the left glass lifter works normally.

7

Inspect the voltage among the terminal No. 20, 19 and 18 of the left front window wire
harness connector DR10 and the body.

(a) Disconnect left front window

harness connector DR10.

(b) Measure terminal voltage by

millimeter.
