CHARGING CHARGING SYSTEM
1996 LAND CRUISER (RM451U)
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.

DIAGNOSTICS ENGINE
DI−7
1996 LAND CRUISER (RM451U)
(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
When closed throttle position switch is ON:
0.1 V  VTA  0.95 V
P0135
P0141The heater circuit in witch an abnormality is detected is
turned offIgnition switch OFF
P0325
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).
