Inspection Procedures
Use the inspection procedures to determine
if the circuit is normal or abnormal. If it is ab-
normal, use it to determine whether the prob-
lem is located in the sensors, actuators, wire
harness or ECU.

Indicates the condition of the connector of the ECU
during the check.


Connections of tester are
indicated by (+), (±) after
terminals name.

1. CHECK BATTERY ELECTROLYTE LEVEL
(a) Check the electrolyte quantity of each cell.
(1) If the electrolyte is under the low level, replace the battery (or add distilled water if possible) and
check the charging system.
2. CHECK BATTERY VOLTAGE
(a) If it has not been 20 minutes since you drove the vehicle
or since the engine was stopped, turn the ignition switch
and the electrical system (headlight, blower motor, rear
defogger etc.) to the on position for 60 seconds. This will
remove the surface charge on the battery.
(b) Turn off the ignition switch and the electrical systems.
(c) Measure the battery voltage between the negative (±)
and positive (+) terminals of the battery.
Standard voltage: 12.5 to 12.9 V at 20C (68F)
HINT:
If the voltage is less than specification, charge the battery.
(d) Check the indicator as shown in the illustration.

3. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loosened or corroded.
(b) Check the fusible links, high±current fuses and regular fuses.
4. INSPECT DRIVE BELT
(a) Visually check the belt for excessive wear, frayed cords
etc.
HINT:

If any defect found, replace the drive belt.

Cracks on the rib side of a belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be
replaced.

2. CHECK BATTERY SPECIFIC GRAVITY
(MAINTENANCE TYPE BATTERY)
(a) Check the specific gravity of each cell.
Standard specific gravity: 1.25 to 1.29 at 20
C (68

HINT:
If the specific gravity is less than specification, charge the bat-
tery.
3. CHECK BATTERY VOLTAGE
