RESET
1. RESET SLIDING ROOF MOTOR
(a) If the AUTO operation function does not operate, reset the sliding roof motor as follows:
(1) Press the sliding roof switch on the TILT UP side and hold it until the sliding roof motor stops.
Then release the switch and leave it untouched for 10 seconds or more.
(2) Press the sliding roof switch on the TILT UP side again for 10 seconds or more and hold it until
the sliding roof glass stops at the fully open and up position.
(3) Release the switch, press it again within 5 seconds and hold it until a series of movements indi-
cated below have been completed:
Fully closing
Fully opening
Fully closing
HINT:
When the battery terminal is disconnected or after the jam protection function has operated, the sliding roof
motor ECU may not detect the position of the roof glass. If the AUTO operation function is still disabled even
after the sliding roof motor is reset, the Hall IC (built in the sliding roof motor) for detecting the roof glass
position may be malfunctioning.

CHARGING SYSTEM (1AZ±FE)
PRECAUTION
1. Check that the battery cables are connected to the correct terminals.
2. Disconnect the battery cables when the battery is given a quick charge.
3. Do not perform tests with a high voltage insulation resistance tester.
4. Never disconnect the battery while the engine is running.
5. Check that the charging cable is tightened on terminal B of the generator and the fuse box.

ON±VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte quantity of each cell.
(1) If the electrolyte is under the low level, replace the battery (or add distilled water if possible) and
check the charging system.
2. CHECK BATTERY VOLTAGE
(a) If it has not been 20 minutes since you drove the vehicle
or since the engine was stopped, turn the ignition switch
and the electrical system (headlight, blower motor, rear
defogger etc.) to the on position for 60 seconds. This will
remove the surface charge on the battery.
(b) Turn off the ignition switch and the electrical systems.
(c) Measure the battery voltage between the negative (±)
and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20C (68F)
HINT:
If the voltage is less than specification, charge the battery.
(d) Check the indicator as shown in the illustration.

3. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loosened or corroded.
(b) Check the fusible links, high±current fuses and regular fuses.
4. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
HINT:

If any defect found, replace the drive belt.

Cracks on the rib side of a belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be
replaced.

(b) Check that it fits properly in the ribbed grooves.
HINT:
Check with your hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
5. VISUALLY CHECK GENERATOR WIRING
(a) Check that the wiring is in good condition.
6. LISTEN FOR ABNORMAL NOISES FROM GENERATOR
(a) Check that there is no abnormal noise from the generator while the engine is running.
7. INSPECT CHARGE WARNING LIGHT CIRCUIT
(a) Turn the ignition switch ON. Check that the charge warning light comes on.
(b) Start the engine and check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warning light circuit.
8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) According to the following procedure, connect an amme-
ter and voltmeter as shown in the illustration.
(1) Disconnect the wire from terminal B of the generator
and connect it to the negative (±) lead of the amme-
ter.
(2) Connect the positive (+) lead of the ammeter to ter-
minal B of the generator
(3) Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
(4) Ground the negative (±) lead of the voltmeter.
(b) Check the charging circuit.
(1) Keep the engine speed at 2,000 rpm, check the
reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 12.9 to 14.9 V
HINT:

If the voltmeter reading is more than standard voltage, re-
place the voltage regulator.

If the voltmeter reading is less than the standard voltage,
check the voltage regulator and generator as follows:
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) Keep the engine speed at 2,000 rpm, turn on the high beam headlights and turn the heater blower
switch to the ºHIº position.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
HINT:

If the ammeter reading is less than standard amperage, repair the generator.

If the battery is fully charged, the indication will sometimes be less than standard amperage.
