Toyota Corolla Repair Manual: On–vehicle inspection
1. Check battery electrolyte level
- Check the electrolyte quantity of each cell (maintenance–free battery).
- If under the lower level, replace the battery (or add distilled
water if possible) and check the charging
system.
- check the electrolyte quantity of each cell (except
maintenance–free battery).
- If under the lower level, add distilled water.
2. Check battery specific gravity
(except maintenance–free battery)

- Check the specific gravity of each cell.
Standard specific gravity: 1.25 – 1.29 At 20 c (68 f)
Hint
:
if the specific gravity is less than specification, charge the battery.
3. Check battery voltage

- After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the engine,
turn the ignition switch on and turn on the electrical
system (headlight, blower motor, rear defogger etc.) For
60 seconds to remove the surface charge.
- turn the ignition switch off and turn off the electrical systems.
- measure the battery voltage between the negative (–)
and positive (+) terminals of the battery.
Standard voltage: 12.5 – 12.9 V at 20 c (68 f)
Hint
:
if the voltage is less than specification, charge the battery.

- Check the indicator as shown in the illustration.
Hint
:
- blue: ok
- white: charging necessary
- red: insufficient water
4. Check battery terminals, fusible link and fuses
- Check that the battery terminals are not loose or corroded.
- check the fusible link, h–fuses and fuses for continuity.
5. Inspect drive belt

- Visually check the belt for excessive wear, frayed cords
etc.
Hint
:

- Check that it fits properly in the ribbed grooves.
Hint
:
check with your hand to confirm that the belt has not slipped out
of the groove on the bottom of the pulley.
6. Visually check alternator wiring
- check that the wiring is in good condition.
7. Listen for abnormal noises from alternator
- check that there is no abnormal noise from the alternator while
the engine is running.
8. Inspect charge warning light circuit
- turn the ignition switch on. Check that the charge warning light
comes on.
- start the engine. Check that the light goes off.
Hint
:
if the light does not operate as specified, troubleshoot the charge warning
light circuit.
9. Inspect charging circuit without load
- if a battery/alternator tester is available, connect the tester
to the charging circuit as permanufacturer’s instructions.

- If a tester is not available, connect a voltmeter to the
charging circuit as follows.
- Disconnect to the wire from terminal b of the alternator
and connect it to the negative (–) lead of the
ammeter.
- Connect the positive (+) lead of the ammeter to terminal
b of the alternator.
- Connect the positive (+) lead of the voltmeter to terminal
b of the alternator.
- Ground the negative (–) lead of the voltmeter.
- Check the charging circuit (denso made).
- With the engine running from idle to 2,000 rpm,
check the reading on the ammeter and voltmeter.
Standard amperage: 10 a or less
standard voltage: 12.9 – 14.9 V
10. Inspect charging circuit with load
- with the engine running at 2,000 rpm, turn on the high beam
headlights and place the heater blower
switch at ”hi”.
- check the reading on the ammeter.
Standard amperage: 30 a or more
Hint
:
- if the ammeter reading is less than standard amperage, repair the
alternator.
- If the battery is fully charged, the indication will sometimes be
less than standard amperage.

Inspection procedure
Hint:
read freeze frame data using the hand-held tester or the obd ii scan tool.
Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, it is
useful for determining whether
the vehicle was running or stopped, the engine was warmed up or not, the ...
