CHARGING GENERATOR
1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT ROTOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
slip rings.
Standard resistance (At 20 °C (68° F): 2.8 − 3.0 Ω
If there is no continuity, replace the rotor.
2. INSPECT ROTOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the slip ring and rotor.
If there is continuity, replace the rotor.
3. INSPECT SLIP RINGS
(a) Check that the slip rings are not rough or scored.
If rough or scored, replace the rotor.
(b) Using a vernier caliper, measure the slip ring diameter. Standard diameter: 14.2 − 14.4 mm (0.559 − 0.567 in.)
Minimum diameter: 12.8 mm (0.504 in.)
If the diameter is less than minimum, replace the rotor.
4. INSPECT STATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
coil leads.
If there is no continuity, replace the drive end frame assembly.
5. INSPECT STATOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the coil lead and drive end frame.
If there is continuity, replace the drive end frame assembly.

COOLANT
INSPECTION
HINT:
Check the coolant level when the engine is cold.
1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the ”LOW” and ”FULL”\
lines.
If low, check for leaks and add engine coolant up to the ”FULL” line.
2. CHECK ENGINE COOLANT QUALITY
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the radiator cap while the engine and radiator
are still hot, as fluid and steam can be blown out under pressure.
(b) There should not be any excessive deposits of rust or scale around the r\
adiator cap or radiator filler
hole, and the coolant should be free from oil.
If excessively dirty, replace the coolant.
(c) Reinstall the radiator cap.

DIAGNOSTICS ENGINE
1996 LAND CRUISER (RM451U)
6. BASIC INSPECTION
When the malfunction code is not confirmed in the DTC check, troubleshooting\
should be performed in the
order for all possible circuits to be considered as the causes of the problem\
s. In many cases, by carrying
out the basic engine check shown in the following flow chart, the location \
causing the problem can be found
quickly and efficiently. Therefore, use of this check is essential in engine troubleshooting.
1 Is battery positive voltage 11 V or more when engine is stopped?
NO Charge or replace battery.
YES
2 Is engine cranked?
NO Proceed to page ST−16 , and continue to trouble-
shoot.
YES
3 Does engine start?
NO Go to step 7.
YES
4 Check air filter.
PREPARATION:
Remove air filter.
CHECK:
Visually check that the air cleaner element is not dirty or exces-
sive oily.
HINT:
If necessary, clean the element with compressed air. First blow
from inside thoroughly, then blow from outside of element.
NG Repair or replace
