CHARGING SYSTEM
ON−VEHICLE INSPECTION
1. CHECK BATTERY ELECTROLYTE LEVEL AND VOLT-
AGE
(a) Check the electrolyte quantity of each cell.
If under the lower level, replace the battery (or add distilled wa-
ter if possible). check the charging system.
(b) Measure the battery voltage between the negative ( −)
and positive (+) terminals of the battery.
Standard voltage: At 20° C (68°F): 12.7 − 12.9 V
HINT:
Before measuring the voltage, turn the ignition switch
OFF and turn off the electrical systems (headlight, blower
motor, rear defogger etc.).
If the vehicle has been running, wait 20 minutes or more
after the vehicle stops before measuring the battery volt-
age.
If the voltage is less than specification, charge the battery.
HINT:
Check the indicator as shown in the illustration.
2. CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES
(a) Check that the battery terminals are not loose or cor-
roded.

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
(a) Turn the ignition switch ”ON”. Check that the discharge warning light comes on.
(b) Start the engine. Check that the light goes off.

HINT:
If your display shows ”UNABLE TO CONNECT TO VEHICLE”
when you have connected the cable of the OBD II scan tool or
TOYOTA hand−held tester to DLC3, turned the ignition switch
ON and operated the scan tool, there is a problem on the ve-
hicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool’s instruction manual.
2. INSPECT DIAGNOSIS (NORMAL MODE)
(a) Check the MIL. (1) The MIL comes on when the ignition switch is turnedON and the engine is not running.
HINT:
If the MIL does not light up, troubleshoot the combination meter
(See page BE−2 ).
(2) When the engine started, the MIL should go off. If the lamp remains on, the diagnosis system has de-
tected a malfunction or abnormality in the system
(b) Check the DTC.
NOTICE:
TOYOTA hand−held tester only: When the diagnosis sys-
tem is switched from normal mode to check mode, it
erases all DTCs and freezed frame data recorded in normal
mode. So before switching modes, always check the DTCs
and freezed frame data, and note them down (1) Prepare the OBD II scan tool (complying with SAE
J 1978) or TOYOTA hand−held tester.
(2) Connect the OBD II scan tool or TOYOTA hand− held tester to DLC3 in the fuse box at the lower left
of the instrument panel.
(3) Turn the ignition switch ON and switch the OBD II
scan tool or TOYOTA hand −held tester switch ON.
(4) Use the OBD II scan tool or TOYOTA hand−held tester to check the DTC and freezed frame data,
note them down. (For operating instructions, see
the OBD II scan tool’s instruction book.)
(5) See page DI−13 to confirm the details of the
DTCs.

DIAGNOSTICS ENGINE
1996 LAND CRUISER (RM451U)
NOTICE:
When simulating symptoms with an OBD II scan tool (ex-
cluding TOYOTA hand −held tester) to check the DTC, use
normal mode. For codes on the DTC chart subject to ”2 trip
detection logic”, turn the ignition switch OFF after the
symptom is simulated the first time. Then repeat the simu-
lation process again. When the problem has been simu-
lated twice, the MIL lights up and the DTCs are recorded in
the ECM.
3. INSPECT DIAGNOSIS (CHECK MODE)
HINT:
TOYOTA hand−held tester only:
Compared to the normal mode, the check mode has an in-
creased sensitivity to detect malfunctions.
Furthermore, the same diagnostic items which are detected in
the normal mode can also be detected in the check mode.
(a) Check the DTC. (1) Initial conditions
Battery positive voltage 11 V or more.
Throttle valve fully closed.
Transmission in ”park” or ”neutral” position.
Air conditioning switched OFF.
(2) Turn ignition switch OFF.
(3) Prepare the TOYOTA hand−held tester.
(4) Connect the TOYOTA hand−held tester to DLC3 in
the fuse box at the lower left of the instrument panel.
(5) Turn the ignition switch ON and push the TOYOTA hand−held tester ON.
(6) Switch the TOYOTA hand −held tester normal mode
to check mode (Check that the MIL flashes.).
(7) Switch the engine (The MIL goes out after the en- gine start.).
(8) Simulate the conditions of the malfunction de- scribed by the customer.
NOTICE:
Leave the ignition switch ON until you have checked the
DTC, etc. (9) After simulating the malfunction conditions, use theTOYOTA hand−held tester diagnosis selector to
check the DTCs and freezed frame data, etc.
HINT:
Take care not to turn the ignition switch OFF. T urning the ignition
switch OFF switches the diagnosis system from check mode to
normal mode, so all DTCs, etc. are erased.

(10) After checking the DTC, inspect the applicable cir-
cuit.
(b) Clear the DTC.
The following actions will erase the DTCs and freezed
frame data.
(1) Operating the OBD II scan tool (complying with SAE
J1978) or TOYOTA hand−held tester to erase the
codes. (See the OBD II scan tool’ s instruction book
for operating instructions.)
(2) Disconnecting the battery terminals or EFI fuse.
NOTICE:
If the TOYOTA hand −held tester switches the ECM from
normal mode to check mode or vice −versa, or if the igni-
tion switch is turned from ON to ACC or LOCK during check
mode, the DTCs and freezed frame data will be erased.
4. FAIL−SAFE CHART
If any of the following codes is recorded, the ECM enters fail −safe mode.
DTC No.Fail−Safe OperationFail− Safe Deactivation Conditions
P0100Ignition timing fixed at 5 ° BTDC
 Injection method fixed at simultaneous injectionReturned to normal condition
P0110Intake air temp. is fixed at 20° C (68°F)Returned to normal condition
P0115Engine coolant temp. is fixed at 80 °(176°F)Returned to normal condition
P0120VTA is fixed at 0°
The following condition must be repeated at least 2 times
consecutively

P0330Max. timing retardationIgnition switch OFF
P1300Fuel cutIGF signal is detected for 6 consective ignitions
P1605Max. timing retardationReturned to normal condition
5. CHECK FOR INTERMITTENT PROBLEMS
TOYOTA hand−held tester only:
By putting the vehicle’s ECM in check mode, 1 trip detection logic is possible instead of 2 trip detection logic
and sensitivity to detect open circuits is increased. This makes it easier \
to detect intermittent problems.
(1) Clear the DTC (See step 2).
(2) Set the check mode (See step 3).
(3) Perform a simulation test (See page IN−18).
(4) Check the connector and terminal (See page IN−28).
(5) Handle the connector (See page IN−28).
(6) Visual check and contact pressure (See page IN−28).
