FUEL PUMP RELAY
INSPECTION
1. REMOVE FUEL PUMP RELAY
(a) Disconnect the fuel pump relay connector.
(b) Remove the bolt and fuel pump relay.
2. INSPECT FUEL PUMP RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity be-
tween terminals +B1 and FPR.
(b) Check that there is continuity between terminals +B2 and
FP.
(c) Check that there is no continuity between terminals +B2
and PR.
If continuity is not as specified, replace the relay.
3. INSPECT FUEL PUMP RELAY OPERATION
(a) Apply battery voltage across terminals +B1 and FPR.
(b) Using an ohmmeter, check that there is no continuity be- tween the +B2 and FP.
(c) Check that there is continuity between terminals +B2 and
PR.
If operation is not as specified, replace the relay.

CONTROL
INSPECTION
1. REMOVE AIR INTAKE CHAMBER (See page EM−28 )
2. DISCONNECT VACUUM HOSES AND CONNECTOR
3. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals. Resistance: 37 − 44 Ω at 20° C (68°F)
If there is no continuity, replace the VSV.
4. INSPECT VSV FOR GROUND
Using an ohmmeter, check that there is no continuity between
each terminal and the body.
If there is continuity, replace the VSV.
5. INSPECT VSV OPERATION
(a) Check that the air flows from pipe E to pipe G.
(b) Apply battery voltage across the terminals.
(c) Check that the air does not flows from pipe E to the filter.
If operation is not as specified, replace the VSV.
6. RECONNECT VACUUM HOSES AND CONNECTOR

1996 LAND CRUISER (RM451U)
INSPECTION
1. INSPECT SHIFT LEVER POSITION
(a) Start the engine, and turn the center diff lock switch to
OFF.
(b) Check that the center diff indicator light comes on when the transfer shift lever shifted to the ”L” position. Check
that the light goes off when the lever is shifted to the ”N”
or ”H” position.
2. INSPECT CENTER DIFF LOCK CONTROL RELAY
(a) Check that there is continuity between the terminals, as shown in the chart.
HINT:
There is a diode between the terminals 6 and 7. If the circuit
shown no continuity, change the positive (+) and negative ( −)
probes and recheck the circuit.
(b) Apply battery positive voltage between the terminals and check that there is continuity between the terminals, as
shown in the chart.
If continuity is not as specified, replace the relay.
