− A.D.D. CONTROL SYSTEM
(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).
