(1) Disconnect the wiring connector from the oil pressure
gauge unit inside the engine compartment.
(2) Apply battery voltage (through the test light) to the gauge
unit side terminal.
(3) Check to be sure that the test light switches OFF when the
engine is stopped, and that it flashes while the engine is
running.
VOLTAGE METER SIMPLE TEST NOEHIGC
(1) Connect a voltmeter for testing.
(2) Turn the ignition key to the ON position.
(3) Compare the readings of the voltmeter for testing and of
the vehicle’s voltage meter. Standard value : 1OV

8-210 AUTOMATIC FREE-WHEELING HUB INDICATOR SYSTEM - General Information
EXPLANATION OF INDICATOR OPERATION
.
1.
2. Automatic free-wheeling hub in locked condition
The
output of the pulse generator is input to $ertninal 4 of the control unit, and the output signals from
the vehicle-speed sensor are input
to termi#al 3 of the control unit.
Only when there are pulse signals from the pulse generator, and when, moreover, the vehicle-speed
signals indicate a vehicle speed of approximatkly 2.5 mph (4 km/h) or highter does the control unit judge
that the automatic free-wheeling hub is the locked condition at the lock-discrimination circuit of the
control unit, and therefore the set signal (locked condition) is output.
This signal is entered into the memory circuit, thus causing the indicator light to illuminate.

When vehicle is stopped (with ignition key still at ON) with automatic free-wheeling hub locked
Signals are not output from the pulse generator and the vehicle-speed sensor when the vehicle is
stopped.
However, because the set signal (locked condition) is entered into the memory circuit, the indicator light
shows the condition in effect when the vehicle was traveling.
