4. If vacuum is not applicable as much as –400mmHg,
and if there is resistance on the intake side, replace
with a new check valve.
VSV Assembly
Inspect the vehicle side harness as follows:

Legend
(1) Grey
(2) Blue
1. Remove connector.
2. Shift transfer lever to 2H and start the engine.
NOTE: Do not move the vehicle while inspection.
3. Make sure that there is continuity in the vehicle side of
harness. If there is no continuity, check transfer shift
switch and wiring.
Inspect both VSVs as follows:
F04RS004
1. With battery not connected (Usual).
A–C:There is continuity
B:Closed
2. With battery connected
A – B:There is continuity
C:Closed
3. If 1) and 2) fail, replace with a new VSV.
Axle Position Switch
412RS048
1. With ball (1) being free
A – B:There is continuity
2. With ball forced into the switch
A – B:No continuity
3. If 1) and 2) fail, replace with a new switch.

15The reference Vb is short-circuited.
If the reference wire (15) is short-circuited to GND, the
speed signal is not generated. If the wire is short-circuited
to the battery voltage, the signal level becomes faulty.
