INSPECTION
1. INSPECT SWITCH POSITION
(a) Start the engine, and shift the transfer shift lever to the ºHº
position.
(b) Check that the center diff. indicator light comes on when
the the switch is in ºONº position. Check that the light goes
off when the switch is in ºOFFº position.
2. 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 is shifted to the ºLº position. Check
that the light goes off when the lever is shifted to the ºNº
or ºHº position.
3. INSPECT CENTER DIFF. LOCK CONTROL RELAY
(a) Check that continuity exists between each terminal, as
shown in the chart.
Tester connected terminal numberSpecified condition

6 - 7*
*: There is a diode between the terminals 6 and 7.
If no continuity exists, check that continuity exists when chang-
ing the position of probe for the position of negative probe
of tester.
(b) Apply battery positive voltage between each terminal and
check that continuity exists between each terminal, as
shown in the chart.
