INITIALIZATION
NOTICE:
• Resetting the power window motor (initializing the
pulse sensor) is necessary when the battery terminal
is disconnected; when the master switch, wire
harness, power window regulator and power window
motor are replaced or removed/installed; or when the
fuses are replaced. AUTO operation function, jam
protection function and remote operation function via
the power window master switch do not operate
without resetting.
• If the AUTO switch (driver side switch) of the master
switch has been continuously operated for a long
time, the power window motor will stop so that no
additional load can be applied to the motor.
Continuing to operate the switch even after the motor
has stopped will cause the switch to blink while
restricting the AUTO UP/DOWN function and the
remote UP/DOWN function. If this happens, reset the
motor again after several minutes have passed.
• Whenever disconnecting the battery terminal, reset all
the other systems besides the power window control
system.
1. RESET POWER WINDOW REGULATOR MOTOR
(DRIVER SIDE)
(a) Turn the ignition switch ON.
(b) Halfway open the power window by pressing the
power window switch.
(c) Fully pull up the switch until the power window is
fully closed and continue to hold the switch for
approx. 1 second after the power window is fully
closed.
(d) Check that the AUTO UP/DOWN function operates
normally.
If the AUTO UP/DOWN function operates normally,
reset operations have been completed at this time.
If not normal, follow steps below.
(1) Disconnect the negative battery terminal for 10
seconds.
(2) Connect the battery terminal.
(3) Perform the above steps (a) to (d) again.
HINT:
If operation is normal, reset operations have
been completed at this time. If not normal, follow
steps (4) to (7).
(4) Turn the ignition switch ON.
(5) Halfway open the power window by pressing the
power window switch.
(6) Fully pull up the switch until the power window is
fully closed and continue to hold the switch for
approx. 12 seconds after the power window is
fully closed.
(7) Check that the AUTO UP/DOWN function
operates normally.

DTC CHECK / CLEAR
NOTICE:
All the stored DTCs and freeze frame data are erased if:
1) the ECM is changed from normal mode to check mode
or vice versa; or 2) the ignition switch is turned from ON
to ACC or off while in check mode.
Before changing modes, always check and make a note
of any DTCs and freeze frame data.
HINT:
• DTCs which are stored in the ECM can be displayed on an
intelligent tester. An intelligent tester can display current
and pending DTCs.
• Some DTCs are not set if the ECM does not detect the
same malfunction again during the second consecutive
driving cycle. However, such malfunctions, detected on
only one occasion, are stored as pending DTCs.
1. CHECK DTC (Using an intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES.
(e) Check for the DTC(s) and freeze frame data, and
then write them down.
(f) Check the details of the DTC(s) (See page ES-56).
2. CLEAR DTC (Using the intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch to the ON position.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CLEAR CODES.
(e) Press the YES button.
3. CLEAR DTC (Without using an intelligent tester)
(a) Perform either one of the following operations:
(1) Disconnect the negative battery cable for more
than 1 minute.
(2) Remove the EFI No. 1 and ETCS fuses from the
Relay Block (R/B) located inside the engine
compartment for more than 1 minute.

ON-VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte level.
(1) If the electrolyte level is low, replace the battery
(or add distilled water) and check the charging
system.
2. CHECK BATTERY SPECIFIC GRAVITY
(a) Check the color of the hydrometer.
Result
3. CHECK BATTERY VOLTAGE
(a) If it has not been 20 minutes since the vehicle was
driven or since the engine was stopped, turn the
ignition switch to the ON position and turn on the
electrical systems (headlights, blower motor, rear
defogger, etc.) for 60 seconds. This will remove the
surface charge from the battery.
(b) Turn the ignition switch off and the electrical
systems off.
(c) Measure the battery voltage between the negative (-
) and positive (+) terminals of the battery.
Standard voltage:
12.5 to 12.9 V at 20
C (68F)
HINT:
If the voltage is below the specification, charge the
battery.
4. CHECK BATTERY TERMINAL
(a) Check that the battery terminals are not loose or
corroded.
If the terminals are corroded, clean them.
5. CHECK FUSES
(a) Measure the resistance of the ALT fuse, ALT-S fuse,
GAUGE fuse and GAUGE 1 fuse.
Standard resistance:
Below 1
If the result is not as specified, replace the fuses as
necessary.
6. CHECK V-RIBBED BELT
(a) Check the belt for wear, cracks or other signs of
damage.
If any of the following defects is found, replace the
V-ribbed belt.
• The belt is worn out, cracked, or the cords are
exposed.
• The cracks reach the cords in more than one
place.
• The belt has chunks missing from the ribs.
