CAUTION:

Prolonged and repeated contact with engine oil will cause removal of natural oils from the skin,
leading to dryness, irritation and dermatitis. In addition, used engine oil contains potentially
harmful contaminants which may cause skin cancer.

Precautions should be taken when replacing engine oil to minimize the risk of your skin making
contact with used engine oil. Wear protective clothing and gloves. Wash your skin thoroughly
with soap and water, or use water-less hand cleaner to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

For environmental protection used oil and used oil filter must be disposed of at designated dis-
posal sites.

ON-VEHICLE INSPECTION
1. INSPECT BATTERY (MAINTENANCE- FREE BAT-
TERY)
(a) Check the battery electrolyte level.
(1) Check the electrolyte quantity of each cell.
If the electrolyte quantity is below the recommended amount,
replace the battery.
(b) 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.
(c) Check the indicator as shown in the illustration.
HINT:

Blue: OK

White: Charging Necessary

Red: Insufficient Water
2. INSPECT BATTERY (EXCEPT MAINTENANCE-FREE
BATTERY)
(a) Check the battery electrolyte level.
(1) Check the electrolyte quantity of each cell.
If the electrolyte quantity is below the recommended amount,
add distilled water.

(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.

6. Engine ECU Replacement
When the Engine ECU is replaced, ECU communication must be completed.
ECU Communication must be performed between the transponder ECU and the
Engine ECU. Complete ECU communication using the following steps:
A. Insert registered Master Key into the ignition cylinder.
B. Turn ignition ON (engine OFF).
C. Short Tc and CG terminals of DLC3 using Diagnosis Check Wire
(SST 09843±18040 or equivalent) and leave for 30 minutes. (See Figure 11.)
