Using voltmeter, backprobe rear differential lock control
unit connector between terminal No. 6 (ground) and specified terminal
under specified conditions. See WIRING DIAGRAMS. See
REAR DIFFERENTIAL LOCK CONTROL UNIT VOLTAGE table. If voltage is not
as specified, replace control unit.

REAR DIFFERENTIAL LOCK DETECTION SWITCH
NOTE: DO NOT apply more pressure than required to bring pressure
gauge reading to about 4 psi (.28 kg/cm).
1) Raise and support vehicle. Remove air pipe and air hose
connections. Connect a pressure gauge and air regulator (for adjusting
compressed air pressure) to air hose. See Fig. 2. Using air regulator,
adjust compressed air pressure until pressure gauge indicates about 4
psi (.28 kg/cm
).
2) While an assistant holds one wheel on one side of vehicle
stationary, slowly turn wheel on other side of vehicle. Using
ohmmeter, check for continuity between rear differential lock
detection switch connector terminals.
3) With air supplied, continuity should exist. With air
released, continuity should not exist. If continuity is not as
specified, replace lock detection switch.

1) Using ohmmeter, check for continuity between specified
rear differential lock switch terminals with switch in specified
positions. See WIRING DIAGRAMS.
2) With lock switch in ON position, continuity should exist
between terminals No. 2 and 5. With lock switch in OFF position,
continuity should exist between terminals No. 2 and 3.
3) Continuity should also exist between terminals No. 1 and 6
with lock switch in ON or OFF position. If continuity is not as
specified, replace lock switch.
REAR DIFFERENTIAL LOCK SYSTEM AIR LEAKAGE CHECK
NOTE: DO NOT apply more pressure than required to bring pressure
gauge reading to about 5 psi (.35 kg/cm).
1) Remove rear differential lock air pump and remove air hose
from air pump. Connect a pressure gauge and air regulator (for
adjusting compressed air pressure) to air hose. Using air regulator,
adjust compressed air pressure until pressure gauge indicates about 5
psi (.35 kg/cm
).
2) Shut off air valve. Wait about 10 minutes and check if air
pressure has dropped. If air pressure has dropped, air hose is not
leaking.
REMOVAL & INSTALLATION
REAR DIFFERENTIAL LOCK AIR PUMP
Removal & Installation
Remove rear seat. Remove bracket from rear differential lock
air pump and remove air pump. Disconnect air hoses from air pump.
Disconnect electrical connector from air pump. To install, reverse
removal procedure.
REAR DIFFERENTIAL LOCK CONTROL UNIT
Removal & Installation
Remove left side lower quarter trim panel in rear
compartment. Remove rear differential lock control unit. Disconnect
electrical connector from control unit. To install, reverse removal
procedure.
