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 CHARGE 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 charge warn-
ing light is lit.
(d) Start the engine. Check that the light goes off.
If the light does not go off as specified, troubleshoot the 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 manufacturer's instructions.
(a) If a tester is not available, connect a voltmeter and amme-
ter to the charging circuit as follows:
(1) Disconnect the wire from terminal B of the genera-
tor, and connect it to the negative (±) tester probe
of the ammeter.
(2) Connect the positive (+) tester probe of the amme-
ter to terminal B of the generator.
(3) Connect the positive (+) tester probe of the voltme-
ter to terminal B of the generator.
(4) Ground the negative (±) tester probe of the voltme-
ter.
(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: 13.5 ± 15.1 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 3 seconds.
HINT:
If the indicator check result is not normal, proceed to
troubleshooting for the ABS warning light circuit
(See page DI±529).
(b) Check the DTC.
(1) Disconnect the short pin from DLC1.
(2) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1.
SST 09843 ± 18020
(3) Turn the ignition switch ON.
(4) Read the DTC from the ABS warning light on the
combination meter.
HINT:

If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI±532 or DI±529).

As an example, the blinking patterns for normal code and
codes 11 and 21 are shown on the left.
(5) Codes are explained in the code table on page
DI±497.
(6) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.

(c) Using TOYOTA hand±held tester, check the DTC.
(1) Hook up the TOYOTA hand±held tester to the
DLC2.
(2) Read the DTC by following the prompts on the tes-
ter screen.
Please refer to the TOYOTA hand±held tester oper-
ator 's manual for further details.
(d) Clear the DTC.
(1) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1 and remove the short pin from DLC1.
SST 09843 ± 18020
(2) Turn the ignition switch ON.
(3) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 5 seconds.
(4) Check that the warning light shows the normal
code.
(5) Remove the SST from the terminals of DLC2 or
DLC1.
SST 09843 ± 18020
(6) Connect the short pin to DLC1.
(e) Using TOYOTA break±out±box and TOYOTA hand±held
tester, measure the ECU terminal values.
(1) Hook up the TOYOTA hand±held tester and
TOYOTA break±out±box to the vehicle.
(2) Read the ECU input/output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand±held tester has a ºSnapshotº function. This re-
cords the measured values and is effective in the diagnosis of
intermittent problems.
Please refer to the TOYOTA hand±held tester/TOYOTA break±
out±box operator's manual for further details.

(2) Using SST, connect terminals Ts and E
1 of DLC1.
SST 09843 ± 18020
(3) Start the engine.
(4) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI±529).
(5) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E
1 of DLC1.
SST 09843 ± 18020
(8) Read the number of blinks of the ABS warning light.
HINT:

See the list of DTC shown on the next page.

If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).

If 2 or more malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
(9) After doing the check, disconnect the SST from ter-
minals Ts and E
1, Tc and E1 of DLC1, and turn igni-
tion switch OFF.
