Battery: Testing and Inspection

1GR-FE BATTERY / CHARGING: CHARGING SYSTEM: 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.

HINT
Before checking the battery voltage, turn off all the electrical systems (headlights, blower motor, rear defogger, etc.).

(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 below 9.6 V, recharge or replace the battery.

(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 (68°F)

* If the electrolyte quantity is above the lower line, check the battery voltage when cranking the engine. If the voltage is below 9.6 V, recharge or replace the battery.

(c) Turn the ignition switch off and turn on the headlights for 20 to 30 seconds. This removes the surface charge from the battery.

(d) Measure the battery voltage between the negative (-) and positive (+) terminals of the battery.

Standard voltage:

12.5 to 12.9 V at 20°C (68°F)

If the voltage is less than the specification, recharge the battery.

2. INSPECT BATTERY TERMINAL AND FUSE

(a) Visually check the battery terminals.

(1) Check that the battery terminals are not loose or corroded.

(b) Check the H-fuse and fuses.
