1986 TOYOTA CAMRY V20 battery

Single Unit Inspection
DIFFERENTIAL LOCK SWITCH
1. INSPECT CONTINUITY OF DIFFERENTIAL LOCK
SWITCH
(a) Disconnect the differential lock switch connector.
(b) Check continuity between terminals 1 to 4.
Switch ON: Continuity
Switch OFF: No continuity
4WD CONTROL SOLENOID
1. INSPECT OPERATION OF 4WD CONTROL SOLENOID
Check air flow of each port when the battery voltage is
applied and is not applied to terminals No.1, No.2 of
the solenoid.
Function Inspection
DIFFERENTIAL LOCK CONTROL
INSPECT DIFFERENTIAL LOCK OPERATION
Start the engine. Check that the differential lock indica-
tor light comes on when the differential lock control
switch is turned to ON. Check that the light goes off
when the switch is turned to OFF.
HINT: After checking the system, turn the control switch
to OFF and check that the differential lock function is
released.
Reference: If the indicator light does not come on and
go out when the control switch is operated, move the
vehicle
slightly forward. when the system is operated it should
be normal.
TRANSFER VACUUM ACTUATOR
1. INSPECT ACTUATOR HOSE CONNECTION
Check that the actuator hoses are connected to the
solenoids and actuator tightly and properly.
