diate connectors C-16, C-33 and relay box connector
A-12, and repair if necessary.

• Check the power supply line for open circuit.

Q: Is the check result normal?

YES :

Go to Step 5.

NO :

Repair the wiring harness.

STEP 5. Retest the system.
(1) Replace the rear panel power window-ECU.

(2) Check that the rear panel power window works

normally.

Q: Is the check result normal?

Inspection Procedure 5: Rear Panel Power Window Timer Function does not Work Normally.

CAUTION

Whenever the ECU is replaced, ensure that the
input and output signal circuits are normal.
COMMENTS ON TROUBLE SYMPTOM
If the rear panel power window timer function does
not work, the input circuit from the ignition switch
(IG1) or the driver's door switch, the communication
lines between the ETACS-ECU and the rear panel
power window-ECU, the rear panel power window-
ECU or the ETACS-ECU may be defective.

PROBABLE CAUSES

• Malfunction of ETACS-ECU

• Malfunction of the rear panel power window-ECU

• Malfunction of the power window main switch

• Malfunction of the rear panel power window

switch

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis code.
When the ignition switch is turned to the "ON" posi-
tion, check that the ETACS-ECU does not set the
diagnosis code.

Q: Is the diagnosis code set?

YES :

Refer to

P.42-29

.

NO :

Go to Step 2.

STEP 2. Check the rear panel power window.
Check that the rear panel power window can operate
by means of the rear panel power window switch.

Q: Is the check result normal?

YES :

Go to Step 3.

NO :

Refer to

P.42-29

.

STEP 3. Check the power window timer function.
Check that the power window timer function works
normally.

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Carry out relevant troubleshooting. Refer to

P.42-29

.

STEP 4. Retest the system.
Check that the rear panel power window timer func-
tion works normally.

Q: Is the check result normal?

YES :

The trouble can be an intermittent

malfunction (Refer to GROUP 00, How to
use Troubleshooting/inspection Service
Points

− How to Cope with Intermittent

Malfunction ).

NO :

Replace the rear panel power window-ECU.

ON-VEHICLE SERVICE

REAR SLIDE WINDOW GLASS
ADJUSTMENT

M1429007400053

Check that the window glass operates smoothly and
moves along the rear slide window glass runchannel
when the rear slide window glass is fully raised and
fully lowered. If there is a problem, adjust by the fol-
lowing procedures:
1. Remove the cab rear end lower trim (Refer to

GROUP 52A, Interior trim ).

2. Remove the waterproof film and rear panel power

window regulator assembly (Refer to

P.42-56

).

3. Stretch the both bends ("A" shown in the figure) of

channel guide on the rear panel window regulator
assembly.
NOTE: The bend of part "A" shown in the figure is
used for positioning the rear panel window regula-
tor assembly. However, stretching the part "A"
enables the adjustment of rear slide window
glass. In addition, keep the part "A" stretched.

4. Install the rear panel power window regulator

assembly (Refer to

P.42-56

).

5. Activate the anti-trap function successively 3

times; this makes the anti-trap function
deactivate.

6. Raise the rear slide window glass and loosen the

channel guide mounting bolts to adjust the
window glass slants appropriately.

7. Set the anti-trap function (Refer to

P.42-55

).

GLASS SLIDING MECHANISM CHECK
AND ADJUSTMENT

M1429000900325

If the window glass automatically starts moving
downwards at the wrong time while it is being raised,
carry out the following adjustment or replacement
procedures:
1. Remove the cab rear end lower trim (Refer to

GROUP 52A, Interior trim ).

2. Remove the waterproof film (Refer to

P.42-56

).

3. Remove the window regulator assembly from the

rear slide window glass, and then raise and lower
the rear slide window glass by hand to check the
operation force.
NOTE: Insert a cushion or similar object to pre-
vent damage to the glass if it should happen to fall
down.

4. If the rear slide window glass does not move up

and down smoothly, check or repair the following
points:

• Check the installation condition of the runchan-

nel.

• Check the installation condition of the rear slide

window sash side and the rear slide window sash
upper.

5. If a repair or an adjustment does not make sense,

replace the rear slide window sash side and the
rear slide window sash upper.

REAR PANEL POWER WINDOW ANTI-
TRAP FUNCTION INSPECTION

M1429007500027

1. Place a wooden board of about 10 mm thickness.

Raise the rear slide window glass with the rear
panel power window switch.

2. Check that the window lowers by fully open

position when the window glass clamps the board.
If this does not happen, carry out troubleshooting.
Refer to

P.42-29

.

NOTE: If the anti-trap function (safety mecha-
nism) is activated consecutively 3 times or more,
make the rear panel power window-ECU learn the

fully closed position of the rear panel power win-
dow (Refer to

P.42-55

).

HOW TO MAKE THE REAR PANEL
POWER WINDOW-ECU LEARN THE
FULLY CLOSED POSITION OF THE REAR
PANEL POWER WINDOW

How to make the rear panel power window-ECU
learn the fully closed position when the rear
panel power window-ECU is removed, or the rear
panel power window regulator assembly is
removed or replaced
1. If the anti-trap function (safety mechanism) is

activated consecutively three times or more, the
fully closed position that the rear panel power
window-ECU has learned will be erased
(initialised).

2. Operate the rear panel power window switch and

fully open the rear slide window glass.

CAUTION

The anti-trap function does not work until the
rear panel power window-ECU completes learn-
ing the fully closed position (It is because the
anti-trap function is reset).
3. Operate the rear panel power window switch and

fully close the rear slide window glass. The rear
panel power window activates for 0.7 second and
stops automatically when the rear panel power
window switch is pressed once. Repeat this
operation until the rear slide window glass fully
closes and release the rear panel power window
switch once. Then, hold the rear panel power
window switch to the fully closed side again for
one second so that the rear panel power window
switch completes learning the fully closed
position.
NOTE: If the rear panel power window switch is
operated to open the rear slide window glass
while the rear panel power window-ECU is learn-
ing, learning will be cancelled. If this happens,
return to step 2.

How to make the rear panel power window-ECU
learn the fully closed position when the rear
panel power window-ECU is replaced with a new
one

CAUTION

The anti-trap function does not work until the
rear panel power window-ECU completes learn-
ing the fully closed position (It is because the
anti-trap function is reset).
Operate the rear panel power window switch to fully
close the rear slide window glass by one-shot up
action so that the rear panel power window-ECU will
complete learning (Initialisation is not needed).
