INSPECTION
1. DISCONNECT NEGATIVE (-) TERMINAL CABLE
FROM BATTERY
2. REMOVE SCUFF PLATE
3. REMOVE ECM PROTECTOR
(a) Take out the front side of the floor carpet.
(b) Remove the 2 nuts and ECM protector.
4. REMOVE ECM
(a) Remove the nut, and disconnect the ECM from the floor
panel.
(b) Fully loosen the bolt and disconnect the 2 ECM connec-
tors, and remove the ECM.
5. INSPECT ECM
(See page DI-164)
6. REINSTALL ECM
(a) Connect the 2 ECM connectors.

Match the male connector correctly with the female
connector, then press them together.

Tighten the bolt.
Make sure the connector is completely connected
by tightening the bolt until there is a clearance of
less than 1 mm (0.04 in.) between the bottom of the
male connector and the end of the female connec-
tor.
(b) Install the ECM with the nut.

INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND-HELD TESTER OR
OBDII SCAN TOOL
(a) Connect the TOYOTA hand-held tester or OBDII scan
tool to the DLC3.
(b) Please refer to the TOYOTA hand-held tester or
OBDII scan tool operator's manual for further details.
3. INSPECT FUEL CUTOFF OPERATION
(a) Increase the engine speed to at least 3,000 rpm.
(b) Check for injector operating noise.
(c) Check that when the throttle lever is released, injector op-
eration noise stops momentarily and then resumes.
HINT:
Measure with the A/C OFF.
Fuel return speed:
1,400 rpm
(Vehicle speed less than 25 km/h (16 mph), with brake
OFF)
4. DISCONNECT TOYOTA HAND-HELD TESTER OR
OBDII SCAN TOOL

6. REMOVE ENGINE UNDER COVER
7. 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.
8. 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.
9. 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:

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
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:

With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.

If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.

If the voltmeter reading is less than standard volt-
age, check the generator.

10. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged the indication will sometimes be
less than standard amperage.
