C: QUICK CHARGE
Fig. 6 INITIAL CHARGING CURRENT SETTING AND CHARGING TIME (Quick charge)
lCheck battery type and determine the specified current using the table shown above.
lAfter starting charging, adjustment of charging current is not necessary.
CAUTION:
lDo not use quick charge method on a battery whose specific gravity is less than 1.100.
lSet initial charging current to value specified in Fig. 6. If charger is not capable of producing spec-
ified current value, set its charging current as close to that value as possible.
lKeep battery away from open flame while it is being charged.
lWhen connecting charger, connect leads first, then turn on charger. Do not turn on charger first,
as this may cause a spark.
lBe careful of a rise in battery temperature because a large current flow is required during quick-
charge operation.
If battery temperature rises above 60°C (140°F), stop charging. Always charge battery when its
temperature is below 60°C(140°F).
lDo not exceed the charging time specified in Fig. 6, because charging battery over the charging
time can cause deterioration of the battery.

OK or NG
OK >> Diagnosis completed
NG >> GO TO 3.
3.G-SENSOR UNIT INSPECTION
1. Disconnect connectors and remove G-sensor from vehicle.
2. Check the voltage under the following condition with the ignition
switch ON: G-sensor harness-side connector M57 terminal
NO.1(W) and body ground
3. Using a test harness, connect 8.0V from the G-sensor harness
connector M57 terminal NO.1(W) to the G-sensor connector ter-
minal 1.
4. Using a test harness, connect from the G-sensor harness con-
nector M57 terminal NO.3(B) to the G-sensor connector terminal
NO.3.
5. With ignition switch ON, when the G-sensor is in horizontal,
check the output voltage under following condition with tilted for-
ward and backward by 90°: terminal NO. 3 and terminal NO. 2.
6. After inspection, install the G-sensor. Erase diagnosis trouble code of the 4WD control unit.
OK or NG
OK >> GO TO 4.
NG >> Replace G-sensor.

1.INSPECTION OF BLOWN FUSE BETWEEN IGNITION SWITCH AND COMBINATION METER
Check blown fuse between ignition switch and combination meter.
OK or NG
OK >> GO TO 2 (No blown fuse)
NG >> Replace the fuse and perform the inspection again.
2.COMBINATION METER POWER SUPPLY CIRCUIT INSPECTION
1. Disconnect combination meter connector.
2. Check voltage between the combination meter harness connector M46 terminal No. LHD models: 46 (W/
L) RHD models: 59 (W/L) and body ground.
OK or NG
OK >> Malfunctioning combination meter.
NG >> Check fuse 10A [#11] to combination meter harness and connector.
4WD WARNING LAMP DOES NOT GO OUT SEVERAL SECONDS AFTER ENGINE
STARTED.(4WD MODE INDICATOR LAMP GOES OUT)
1.PERFORM SELF-DIAGNOSIS
Using CONSULT-II perform self-diagnosis.
OK or NG
OK >> No malfunction detected. Perform inspection again.
NG >>
lDetermine the location of the malfunction according to the result of Self-diagnosis using CON-
SULT-II. (Malfunction is present in the 4WD system.)
