CONTROL VALVE
INSPECTION
1. REMOVE VSV
Disconnect the 2 connectors and 4 vacuum hoses, and remove
the 2 bolts and VSV.
2. INSPECT VSV FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
terminals.
Resistance: 33 − 39 Ω at 20 °C (68 °F)
If there is no continuity, replace the VSV.
3. 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.
4. INSPECT VSV OPERATION
(a) Check that air flows from port E to port G.
(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to the filter.
If operation is not as specified, replace the VSV.
5. REINSTALL VSV
(a) Install the VSV with the 2 bolts.
Torque: 8 N·m (80 kgf·cm, 71 in.·lbf)
(b) Connect the 2 connectors and 4 vacuum hoses to the 2
VSV.

(b) Connect the battery to the solenoid.
Check that air flows from the port E to port F.
Check that air does not flow from the port E to the air filter.
(c) Disconnect the battery positive voltage from the solenoid.
Check that air flows from the port E to the air filter.
Check that air does not flow from the port E to port F.
5. INSPECT A.D.D. RELAY
(a) Using an ohmmeter, check that continuity exists between
terminals 1 and 3.
(b) Using an ohmmeter, check that continuity exists between
terminals 2 and 6.
(c) Connect the positive (+) lead from the battery to terminal
6 and the negative (−) lead to terminal 2.
(d) Using an ohmmeter, check that continuity exists between
terminals 1 and 4.
6. INSPECT A.D.D. INDICATOR SWITCH
(a) Using an ohmmeter, check that continuity exists between
terminals when the switch when the switch is pushed (dif-
ferential connected position).
(b) Using an ohmmeter, check that continuity doesn’t exists
when the switch is free (differential disconnected posi-
tion).
7. INSPECT TRANSFER INDICATOR SWITCH
(a) Using an ohmmeter, check that there is continuity be-
tween terminals between terminals when the switch is
pushed (transfer 4WD position).
(b) Using an ohmmeter, check that there is continuity be-
tween terminals when switch is free (transfer H2 position).
