ON-VEHICLE INSPECTION
1. CHECK BATTERY CONDITION
NOTICE:
If the battery is weak or if the engine is difficult to
start, perform the following procedures.
(a) Check the battery for damage and deformation. If
severe damage, deformation or leakage is found,
replace the battery.
(b) Check the electrolyte quantity of each cell.
(1) For maintenance-free batteries:
• If the electrolyte quantity is below the lower
line, replace the battery.
• If the electrolyte quantity is above the lower
line, check the battery voltage when
cranking the engine. If the voltage is less
than 9.6 V, recharge or replace the battery.
HINT:
Before checking the battery voltage, turn off
all the electrical systems (headlights, blower
motor, rear defogger, etc.).
(2) For non-maintenance-free batteries:
• If the electrolyte quantity is below the lower
line, add distilled water to each cell. Then,
recharge the battery and check the
electrolyte's specific gravity.
Standard specific gravity:
1.25 to 1.29 at 20
C (68F)
If the electrolyte quantity is above the lower
line, check the battery voltage when
cranking the engine. If the voltage is less
than 9.6 V, recharge or replace the battery.
HINT:
Before checking the battery voltage, turn off
all the electrical systems (headlights, blower
motor, rear defogger, etc.).
2. INSPECT BATTERY TERMINAL AND FUSE
(a) Visually check the battery terminals.
(1) Check that the battery terminals are not loose
or corroded.
(b) Measure the resistance of the H-fuses and fuses.
Standard resistance:
Below 1
If the results are not as specified, replace the fuses
as necessary.

8. 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 "HI" 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.
HINT:
If the battery is fully charged, the indication will
sometimes be less than the standard amperage. If
this is the case, add more electrical load (operate
the wipers, rear window defogger, etc.) and check
the reading on the ammeter again.

(c) Manual light control system:
This system functions when lights such as the
headlights and taillights are illuminated by manual
operation of the light control switch.
(1) The main body ECU receives the following
signals (D).
• Light control switch signal
• Headlight dimmer switch signal
• Front fog light switch signal
(2) The main body ECU controls the following
signals based on the signals listed in D (E).
• Headlight relay operation signal
• Taillight relay operation signal
• Daytime running light No. 2 relay operation
signal
• Daytime running light No. 3 relay operation
signal
• Daytime running light No. 4 relay operation
signal
• Front fog light relay operation signal
(3) The main body ECU controls the on/off
operation of the following parts based on the
signals listed in E.
