1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT HAZARD WARNING SWITCH CONTINUITY
ConditionTester connectionSpecified condition
Switch OFF7 − 10Continuity
Switch ON7 − 8
4 − 5 − 6 − 9Continuity
Illumination circuit2 − 3Continuity
If continuity is not as specified, replace the switch.
2. INSPECT TURN SIGNAL FLASHER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative ( −) lead to terminal 3.
(b) Connect the 2 turn signal light bulbs parallel to each other
to terminals 1 and 3, and check that the bulbs flash.
HINT:
The turn signal lights should flash 60 to 120 times per minute.
If one of the front or rear turn signal lights has an open circuit,
the number of flashes will be more than 140 per minute.
If operation is not as specified, replace the flasher.

7. INSPECT FUEL SENDER GAUGE OPERATION
(a) Connect a series of three 1.5 V dry cell batteries.
(b) Connect the positive (+) lead from the dry cell batteries to
terminal 4 through a 3.4 W test bulb and the negative ( −)
lead to terminal 5.
(c) Connect the positive (+) lead from the voltmeter to termi- nal 4 and the negative ( −) lead to terminal 5.
(d) Check that the voltage rises as the float is moved from the
full to empty position.
8. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 4 and 5.
Float position: mm (in.)Resistance (Ω )
F: Approx. 15.0 (0.591)Approx. 3.0
E: Approx. 200.0 (7.874)Approx. 110.0
If resistance value is not as specified, replace the sender
gauge.
9. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 5 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminals 1 and 5
through a 3.4 W test bulb, and check that the bulb lights
up.
HINT:
It will take a short time for the bulb to light up.
(b) Submerge the switch in fuel, and check that the bulb goes
out.
If operation is not as specified, replace the sender gauge.

sistance.
14. INSPECT OIL PRESSURE RECEIVER GAUGE RESIS- TANCE
Measure the receiver gauge resistance between terminals. Resistance:
40 − 48 Ω
If resistance value is not as specified, replace the receiver
gauge.
15. INSPECT OIL PRESSURE SENDER GAUGE OPERA-
TION
(a) Disconnect the connector from the sender gauge.
(b) Apply battery positive voltage to the sender gauge termi- nal through a test LED.
(c) Check that the bulb does not light when the engine is stopped.
(d) Check that the LED flashes when the engine is running. The number of flashed should vary with engine speed.
If operation is not as specified, replace the sender gauge.
16. INSPECT BRAKE WARNING LIGHT
(a) Disconnect the connectors from the level warning switch and parking brake switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Turn the ignition switch ON, and check that the warning light lights up.
17. INSPECT PARKING BRAKE SWITCH
(a) Check that there is continuity between terminal and the switch set nut with switch pin released (parking brake le-
ver pulled up).
(b) Check that there is no continuity between terminal and the switch set nut with switch pin pushed in. (parking
brake lever released)
If operation is not as specified, replace the switch.

18. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Check that there is no continuity between terminals with
the switch OFF (float up).
(b) Check that there is continuity between terminals with the switch ON (float down).
If operation is not as specified, replace the switch.
19. INSPECT OPEN DOOR WARNING LIGHT
(a) Disconnect the connector from the door courtesy switch and ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, and check that the warning light lights up.
If the warning light does not light up, test the bulb.
20. INSPECT DOOR COURTESY SWITCH
(a) Check that there is continuity between terminal and the
switch body with the switch ON (switch pin re-
leased:opened door).
(b) Check that there is no continuity between terminal and
the switch body with the switch OFF (switch pin pushed
in:closed door).
If operation is not as specified, replace the switch.
21. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the seat belt warning relay.
(b) Ground terminal 9 on the wire harness side connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
22. INSPECT SEAT BELT BUCKLE SWITCH CONTINUITY
(a) Check that there is continuity between terminals with the switch ON (belt unfastened).
(b) Check that there is no continuity between terminals with the switch OFF (belt fastened).
If operation is not as specified, replace the seat belt inner.
