CHARGING SYSTEM
ON-VEHICLE INSPECTION
CAUTION:
Check that the battery cables are connected to the
correct terminals.
Disconnect the battery cables when the battery is giv-
en a quick charge.
Do not perform tests with a high voltage insulation re-
sistance tester.
Never disconnect the battery while the engine is run-
ning.
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 wa-
ter if possible). Check the charging system.
Except Maintenance-Free Battery:
If under the lower level, add distilled water.
2. Except Maintenance-Free Battery:
CHECK BATTERY SPECIFIC GRAVITY
Check the specific gravity of each cell.
Standard specific gravity: 1.25 - 1.29 at 20°C (68°F)
If the specific gravity is less than specification, charge the bat-
tery.
3. Maintenance-Free Battery:
CHECK BATTERY VOLTAGE
(a) After having driven the vehicle and in the case that 20
minutes have not passed after having stopped the en-
gine, 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.
(b) Turn the ignition switch OFF and turn off the electrical sys-
tems.
(c) 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)
If the voltage is less than specification, charge the battery.

After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
6. VISUALLY CHECK GENERATOR WIRING AND
LISTEN FOR ABNORMAL NOISES
(a) Check that the wiring is in good condition.
(b) Check that there is no abnormal noise from the generator
while the engine is running.
7. CHECK DISCHARGE WARNING LIGHT CIRCUIT
(a) Warm up the engine and then turn it off.
(b) Turn off all accessories.
(c) Turn the ignition switch ºONº. Check that the discharge
warning light is lit.
(d) Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the dis-
charge light circuit.
8. INSPECT CHARGING CIRCUIT WITHOUT LOAD
HINT:
If a battery/generator tester is available, connect the tester to
the charging circuit as per the manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (-) probe of the
ammeter.
Connect the positive (+) probe of the ammeter to
terminal B of the generator.
Connect the positive (+) probe of the voltmeter to
terminal B of the generator.
Ground the negative (-) probe of the voltmeter.
(b) Check the charging circuit as follows:
With the engine running from idling to 2,000 rpm, check
the reading on the ammeter and voltmeter.
Standard amperage: 10 A or less
Standard voltage: 13.2 -14.8 V

INSPECTION
1. REMOVE IGNITION RELAY (Marking: IG1)
2. INSPECT IGNITION RELAY
(a) Inspect the relay continuity.
(1) Using an ohmmeter, check that there is no continu-
ity between terminals 1 and 2.
If there is continuity, replace the relay.
(2) Check that there is continuity between terminals 3
and 4.
If there is no continuity, replace the relay.
(b) Inspect the relay operation.
(1) Apply battery positive voltage across terminals 3
and 4.
(2) Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
If there is no continuity, replace the relay.
3. REINSTALL IGNITION RELAY

1. CHECK COOLING FAN OPERATION WITH LOW TEM-
PERATURE (Below 83°C (181°F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fans stop.
If not, check the cooling fan relays and ECT switches.
(c) Disconnect the No.1 ECT switch wire connector.
(d) Connect terminals on the No.1 ECT switch wire connec-
tor.
(e) Check that the No.1 cooling fan rotates at high speed.
If not, check the No.1 cooling fan relay and No.1 cooling fan.
(f) Reconnect the No.1 ECT switch connector.
(g) Disconnect the No.2 ECT switch connector.
(h) Ground terminal on the No.2 ECT switch wire harness
side connector.
(i) Check that the No.1 and No.2 cooling fans rotate at low
speed.
If not, check the No.2 cooling fan relay, No.3 cooling fan relay
and No.2 cooling fan.
(j) Reconnect the No.2 ECT switch connector.

If the ECU detects trouble, the ABS warning light lights up and ABS control is prohibited at the same time.
At this time, the ECU records a DTC in memory.
Connecting terminals Tc and E
1 of the DLC1 makes the ABS warning light blink and output the DTC.
