3. INSPECT DRIVE BELTS
(a) Visually check the drive belt for cracks, oiliness or wear.
Check that the belt does not touch the bottom of the pulley
groove.
If necessary, replace the drive belts as a set.
(b) Using a belt tension gauge, measure the belt tension. Belt tension gauge:
Nippondenso BTG−20 (95506 −00020)
Borroughts No. BT−33−73F
Drive belt tension:
New belt400 − 580 N (41.0 − 59.1 kgf, 90.4 − 130.2 lbf)
Used belt200 − 390 N (20.4 − 40.0 kgf, 45.0 − 88.2 lbf)
If the belt tension is not as specified, adjust it.
HINT:
”New belt” refers to a belt which has been used less than
5 minutes on a running engine.
”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.
After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
4. VISUALLY CHECK GENERATOR WIRING AND LIS- TEN 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.
5. INSPECT DISCHARGE WARNING LIGHT CIRCUIT

CHARGING CHARGING SYSTEM
1996 LAND CRUISER (RM451U)
If the light does not operate as specified, troubleshoot the dis-
charge warning light circuit.
6. 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 generator
and connect it to the negative ( −) lead of the amme-
ter.
Connect the positive (+) lead of the ammeter to ter-
minal B of the generator.
Connect the positive (+) lead of the voltmeter to ter-
minal B of the generator.
Ground the negative ( −) lead of the voltmeter.
(b) Check the charging circuit as follows:
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:
at 25° C ’(77°F)14.0 − 15.0 V
at 115°C ’(239° F)13.5 − 14.3 V
If the voltmeter reading is more than standard voltage, replace
the voltage regulator.
If the voltmeter reading is less than the 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.
7. 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
”HI”.

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 trou-
bleshooting for the ABS warning light circuit (See page
DI−230 ).
When the transfer is in L position (center dif ferential lock),
the ABS does not operate and the ABS warning light
stays ON.
(b) Check the DTC. (1) Confirm that the center differential is free.
(2) Disconnect the short pin from the DLC1.
(3) Using SST, connect terminals Tc and E
1 of the
DLC1.
SST 09843−18020
(4) Turn the ignition switch ON.
(5) 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−233 or DI−230 ).

If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.
(c) Clear the DTC.
(1) Confirm that the center differential is free.
(2) Using SST, connect terminals Tc and E
1 of the
DLC1 and remove the short pin from the DLC1.
SST 09843−18020
(3) Turn the ignition switch ON.
(4) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds.
(5) Check that the warning light shows the normal
code.
(6) Remove the SST from the terminals of the DLC1.
SST 09843−18020
(7) Connect the short pin to the DLC1.
HINT:
Cancellation can also be done by removing the ECU −B fuse,
but in this case, other memory systems will also be cancelled

(d) Using TOYOTA break −out− box and TOYOTA hand− held
tester, measure the ECU terminal values.
(1) Hook up the T OYOTA hand−held tester and TOYO-
TA 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 ”Snapshot ” 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 operators manual for further details.
2. SPEED SENSOR SIGNAL AND DECELERATION SEN-
SOR CHECK

(2) Turn the ignition switch OFF.
(3) Using SST, connect terminals Ts and E
1 of the
DLC1.
SST 09843−18020
(4) Start the engine.
(5) 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−230).
