connector terminal 2B (position sensor 2
signal).
• Does voltage alternate between 0 V and
approximately 12 V when driver-side front
window is being gone up down?
Yes Replace power window main switch. (malfunction in power
window main switch automatic mode control), then go to
Step 11.
No Go to next step.
8 VERIFY POSITION SENSOR 2 OUTPUT
SIGNAL
• Turn ignition switch to ON position.
• Test voltage at driver-side front power
window motor connector terminal G (position
sensor 2 signal).
• Is voltage alternate between 0 V and
approximately 12 V when driver-side front
window is being gone up down?
Yes Go to next step.
No Replace driver-side front power window motor, then go to
Step 12.
9 VERIFY WHETHER MALFUNCTION IS IN
WIRING HARNESS (BETWEEN POWER

FRONT POWER WINDOW MOTOR) OR
ELSEWHERE
• Turn ignition switch to LOCK position.
• Disconnect power window main switch
connector and driver-side front power
window motor connector.
• Is there continuity between power window
main switch connector terminal 2B (position
sensor 2 signal) and driver-side front power
window motor connector terminal G (position
sensor 2 signal)?
Yes Go to next step.
No Repair wiring harness between power window main switch
and driver-side front power window motor, then go to Step
12.
10 VERIFY WHETHER MALFUNCTION IS IN
WIRING HARNESS (BETWEEN POWER
WINDOW MAIN SWITCH AND DRIVER-SIDE
FRONT POWER WINDOW MOTOR) OR
ELSEWHERE
• Is there continuity between power window
main switch connector terminal 2B (position
sensor 2 signal) and ground?
Yes Repair wiring harness between power window main switch
and driver-side front power window motor, then go to Step
12.
No Go to next step.
11 VERIFY WHETHER MALFUNCTION IS IN
WIRING HARNESS (BETWEEN POWER
WINDOW MAIN SWITCH AND DRIVER-SIDE
FRONT POWER WINDOW MOTOR) OR
POWER WINDOW MAIN SWITCH
• Turn ignition switch to ON position.
• Measure voltage at power window main
switch connector terminal 2B (position
sensor 2 signal).
• Is voltage approximately 12 V?
Yes Repair wiring harness between power window main switch
and front driver-side power window motor, then go to next
step.
No Replace power window main switch (open or short to B+/
ground in power window main switch), then go to next step.
12 RECHECK MALFUNCTION SYMPTOM AFTER
REPAIR
• Did malfunction disappear?
Yes • Troubleshooting completed.
• Explain repairs to customer.
No Recheck malfunction symptoms, then repeat from Step 1 if
malfunction recurs.
