(b) Check the battery specific gravity.
(1) Check the specific gravity of each cell.
Standard specific gravity: 1.25 to 1.29 at 20C (68F)
If the specific gravity is less than specification, charge the bat-
tery.
(c) Check the battery voltage.
(1) If it has been less than 20 minutes since you
stopped driving the vehicle or since the engine was
stopped, turn the ignition switch and electrical sys-
tems (headlight, blower motor, rear defogger etc.)
to the ON position for 60 seconds. This will remove
the surface charge on the battery.
(2) Turn the ignition switch and electrical systems OFF.
(3) Using a voltmeter, measure the battery voltage be-
tween the negative (-) and positive (+) terminals of
the battery.
Standard voltage: 12.5 to 12.9 V at 20C (68F)
If the voltage is less than the specification, charge the battery.
(d) Check the indicator as shown in the illustration.
HINT:
Blue: OK
White: Charging Necessary
Red: Insufficient Water
3. INSPECT BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Visually check the battery terminals.
(1) Check that the battery terminals are not loosened or corroded.
(b) Visually check the fusible link and fuses.
(1) Check that there is continuity of the fusible links, high current fuses and regular fuses.
4. INSPECT V-RIBBED BELT
(a) Visually check the belt for excessive wear, frayed cords,
etc.
If any defects are found, replace the v-ribbed belt.
Cracks on the rib side of the belt are considered ac-
ceptable.
If the belt has chunks missing from the ribs, it should
be replaced.

(b) Check that the belt fits properly in the ribbed grooves.
Confirm that the belt has not slipped out of the groove on the
bottom of the pulley by hand.
5. INSPECT GENERATOR WIRING
(a) Visually check the generator wiring.
(1) Check that the wiring is in good condition.
6. INSPECT ABNORMAL NOISES
(a) Listen to abnormal noises from generator.
(1) Check that no abnormal noise is heard 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, then check that the light goes off.
If the light does not operate as specified, troubleshoot the charge warning light circuit.
8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a tester is not available, connect a voltmeter to the
charging circuit as follows.
(1) Disconnect the wire from terminal B of the genera-
tor, then connect it to the negative (-) lead of the
ammeter.
(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, then check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 to 14.8 V
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn the high beam headlights ON and turn the heater blower
switch to the ºHIº position.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, repair the generator.
If the battery is fully charged, the indication will sometimes be less than the standard amperage.

D.C.C. FUSE INSTALLATION DURING PDS
The D.C.C. fuse has been removed at the assembly plant to reduce parasitic current
draw in transit and storage.
The removed D.C.C. fuse (30 A) is stored in the blank space of the Junction Block in
the engine compartment. The D.C.C. fuse must be reinstalled during Pre±Delivery
Service (PDS) in the dealership as shown below.
Junction Block
Install D.C.C. Fuse (30 A)
Here (Original Location)Remove This Fuse
NOTE:
Removing the D.C.C. fuse cuts off power sources relating to the Dome, ECU±B and
RAD No. 1 fuses.
If the vehicle is stored in the dealership for a long period of time after PDS,
disconnect the negative battery terminal to prevent battery discharge. Refer to TSIB
PG009±02 for battery maintenance information.

INITIALIZATION OF MOON ROOF
The moon roof is controlled by the sliding roof ECU which detects and memorizes the
moon roof position by counting pulses of its motor from the fully tilt±up position as the
start position. Once the battery terminal has been disconnected and reconnected, the
sliding roof ECU does not detect and memorize the moon roof position, resulting in no
functions of the ªone±touch tilt up and down,º ªone±touch slide open and closeº and ªjam
protection.º Please initialize the moon roof position after reconnecting the battery
terminal as outlined below.
1. Turn the ignition switch to the
ªONº position.
2. Push and hold the moon roof switch
to the ªTILT± UPº side until the moon
roof tilts all the way up and then tilts
down slightly (approximately 10 mm
at rear end).
3. Check for proper operation of the
ªOne±touch slide open and closeº and
ªOne±touch tilt up and downº functions
by pushing the switch briefly to the
ªSLIDE OPENº and ªTILT UPº positions.
NOTE:
Jam protection function becomes
effective through the above
initialization procedure.
