NOTICE:

Do not perform circling calibration of the compass in
a place where the earth's magnetic field is subject to
interference by artificial magnetic fields (under-
ground parking, under a steel tower, between build-
ings, roof parking, near a crossing, near a large ve-
hicle, etc.).

During calibration, do not operate electric systems
(moonroof, power windows, etc.) as they may inter-
fere with the calibration.

If you want to cancel the calibration before it is com-
plete, push the ºMODEº button again.
HINT:
A compass could be magnetized during by vessels of freight
cars. Before delivery, therefore, make sure to perform calibra-
tion and ensure that calibration can be done. If cannot be done
(cannot complete in spite of driving round several times), it may
be caused by magnetization. Demagnetize the vehicle using a
demagnetizer and preform calibration again.
3. PERFORM DEVIATION CALIBRATION
(a) Stop the vehicle and push the ºMODEº button several
times until ºZONE XXº appears on the calender display.
(b) Then push the ºRESET/ADJº button, referring to the fol-
lowing map to select the number of the zone where the
vehicle is.
(c) After calibration, push the ºMODEº button several times
until the calendar display returns to the normal mode.

HOW TO RESET POWER WINDOW MOTOR (LIMIT SWITCH)
NOTICE:
If the jam protection function is not functioning properly, perform the following procedures.
HINT:
It is necessary to reset the power window motor (in initial position for the limit switch) when separating the
window regulator from the power window motor or operating the window regulator with the door glass not
installed.
(a) Remove the power window motor.
HINT:
Place matchmarks on the power window motor and window regulator gear.
(b) Connect the power window motor and power window switch to the wire harness of the vehicle.
(c) Turn the ignition switch ON.
(d) Press the power window UP switch until the motor completes 6 to 10 rotations (4 seconds of rotation
or more).
(e) Assemble the power window motor and regulator.
HINT:

Install the motor when the regulator arm is below the middle point.

Align the matchmarks on the power window motor and window regulator gear when installing the pow-
er window motor.
(f) Assemble the power window regulator and door glass.
HINT:
Never rotate the motor downward until the completion of the window glass installation.
(g) Connect the power window switch to the wire harness and turn the ignition switch ON.
(h) Repeat UP and DOWN operation several times manually.
(i) Check AUTO UP " AUTO DOWN automatic operation is normal.
NOTICE:

The jam protection function does not operate immediately after performing reset.

If the jam protection function is triggered and the window lowers after the window has been fully
closed by AUTO UP operation (step i), reset the power window motor again.
(j) Check the power window function.

INSPECTION
1. Using an ammeter:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 1 on the wire harness side connector and the negative
(-) lead to negative (-) terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
14 on the wire harness side connector.
(d) As the window goes down, check that the current flow is
approximately 7 A.
(e) Check that the current increases up to approximately
14.5 A or more when the window stops going down.
HINT:
The PTC opens some 4 - 90 seconds after the window stops
going down, so that check must be made before the PTC oper-
ates.
If the operation is as specified, replace the driver door ECU.
2. Using an ammeter with a current-measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Remove the driver door ECU with connectors connected.
(b) Attach a current-measuring probe to terminal 25 of the
wire harness.
(c) Turn the ignition switch ON and set the power window
switch in the down position.
(d) As the window goes down, check that the current flow is
approximately 7 A.
(e) Check that the current increases up to approximately
14.5 A or more when the window stops going down.
HINT:
The PTC opens some 4 - 90 seconds after the window stops
going down, so that check must be made before the PTC oper-
ates.
If operation is as specified, replace the driver door ECU.

Apply B+ between
terminals 1 and 2.3 - 5Continuity
If continuity is not as specified, replace the relay.
5. Driver 's Door:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (-) lead to terminal 2, and check that
the motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
If operation is not as specified, replace the motor.
NOTICE:
Since the jam protection may not work properly be sure to
conduct procedures described in ºHOW TO RESET POW-
ER MOTOR (RESET AND PULSE SWITCH)º after this in-
spection.
6. Front Passenger's Door:
INSPECT POWER WINDOW MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 1, and check that
the motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
If operation is not as specified, replace the motor.
