COMMENTS ON TROUBLE SYMPTOM

The revolution detection sensor, which is incorpo-
rated in the power window regulator motor, may be
defective.

POSSIBLE CAUSES

• Malfunction of the power window regulator 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.42-24

).

Q: Is the check result normal?

YES :

Adjust the door window glass (Refer to

GROUP 42

− Door − On-vehicle service

P.42-23

), and then go to Step 2.

NO :

Replace the defective power window
regulator 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.42-29

).

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.42-29

).

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: E-05 power window
main switch connector and E-02 front power
window regulator motor (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 E-05
power window main switch connector terminal
Nos.8, 9, 10 and 12 to E-02 front power window
regulator motor (RH) connector terminal Nos.5, 2,
3 and 6.

• 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 func-
tion 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 front power window regulator
motor assembly (LH).
