COMMENTS ON TROUBLE SYMPTOM

The revolution detection sensor, which is 
incorporated in the power window motor, may be 
defective.

POSSIBLE CAUSES

• Malfunction of the power window motor

DIAGNOSIS PROCEDURE

Step 1. Check the power window operating 
current.

Check that the power window operating current is 
normal (Refer to GROUP 42 

− Door − On-vehicle 

Service 

P.42-29

).

Q: Is the check result normal?

YES : 

Adjust the door window glass (Refer to 

GROUP 42 

− Door − On-vehicle service 

P.42-25

), and then go to Step 2.

NO : 

Replace the defective power window motor 
assembly which operating current are 
abnormal.

Step 2. Confirm the power window learning 
function.

Check that the power window switch has learned the 
fully closed position of the windows (Refer to 
GROUP 42 

− Door 

P.42-35

).

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Make the power window switch learn the 
fully closed position of the windows (Refer 
to GROUP 42 

− Door 

P.42-35

).

Step 3. Determine a trouble spot.

Q: Which door does the power window anti-trap 

function fail on?

Driver's door <LH drive vehicles> : 

Go to Step 4.

Driver's door <RH drive vehicles> : 

Go to Step 7.

Front passenger's door <LH drive vehicles> : 

Go 

to Step 10.

Front passenger's door <RH drive vehicles> : 

Go 

to Step 16.

Rear right door : 

Go to Step 22.

Rear left door : 

Go to Step 28.

Step 4. Connector check: F-05 power window 
main switch connector and F-10 power window 
motor (front: LH) connector.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Repair the defective connector.

Step 5. Check the wiring harness from F-05 
power window main switch connector terminal 
Nos.8, 9, 10 and 12 to F-10 power window motor 
(front: LH) connector terminal Nos.6, 2, 4 and 5.

• Check the input and output lines to the revolution 

detection sensor for open or short circuit.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the wiring harness.

Step 6. Retest the system.

After the power window main switch is replaced, 
check that the driver's power window anti-trap 
function works.
(1) Replace the power window main switch.
(2) Check that the driver's power window anti-trap 

function works.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Replace the power window motor (front: 
LH).
