Driver-side front window does not go up and down in automatic mode

POSSIBLE

CAUSE

• Open or short to B+ circuit in position sensor 1 signal, ground signal from wiring harness (between

power window main switch and driver-side front power window motor), inner power window main
switch, or inner motor: Steps 3–6

• Open or short to B+/ground circuit in position sensor 2 signal from wiring harness (between power

window main switch and driver-side front power window motor), inner power window main switch, or
inner motor: Steps 7–11

Note

• The automatic function and the ignition off timer function do not operate while power window main

switch is in fail-safe mode. The fail-safe operates when position sensor 1, and/or position sensor 2,
and/or position sensor 2 power supply malfunctions.

• Position sensor 1 and/or 2 malfunction

— When driver-side front window is kept up down, main switch can not sense a pulse signal from

position sensor 1 during that can sense 5 pulses (2.5 cycles) from position 2.

— When driver-side front window is kept up down, main switch can not sense a pulse signal from

position sensor 2 during that can sense 5 pulses (2.5 cycles) from position 1.

— There are 3 abnormal pulse from a pulse signal during driver-side front window is kept up or

down.

— There are 20 cycle pulses from a close position during driver-side front window is kept up.
— There is no pulse signal during 1 sec. after down is operated.
