5. The differential lock switch terminals are identified in
circuitry of the differential lock switch is shown in the
(page 6–17). With the use of a multimeter (ohms setting), test the switch
functions to determine if the continuity exists between the various terminals
for each switch position. Check the continuity between the switch terminals.

6. Replace the differential lock switch if the testing determines it is damaged.
7. If the differential lock switch testing is correct and a circuit problem still exists,
check the wire harness; refer to the Electrical Schematics and Wire Harness
Drawings/Diagrams in
8. After you complete the testing, connect the machine wire harness connector
to the differential lock switch.
9. Install the dash panel to the steering column; refer to
Assembly (page 7–7).
