Battery: Testing and Inspection

2UR-GSE 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 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 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 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.).

(c) Check the voltage.

(1) Turn the engine switch off and turn on the headlights for 20 to 30 seconds. This will remove the surface charge from the battery.

(2) Measure the battery voltage according to the value(s) in the table below.

Standard Voltage:





HINT
If the voltage is not as specified, charge the battery.

2. CHECK BATTERY TERMINAL AND FUSE

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

If the terminals are corroded, clean the terminals.

(b) Measure the resistance of the charging fuses.

Standard resistance:

Below 1 Ohms

If the result is not as specified, replace fuses as necessary.
