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.
