5. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1
and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0 V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be 4 times for every revolution of
the speed sensor shaft.
If operation is not as specified, replace the sensor.
6. INSPECT SPEEDOMETER RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as the specified, replace the meter.
7. INSPECT TACHOMETER/ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
NOTICE:

Reversing the connection of the tachometer will dam-
age the transistors and diodes inside.

When removing or installing the tachometer, be care-
ful not to drop or subject it to heavy shocks.
(b) Compare the tester and tachometer indications.

19. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
OPERATION
(a) Remove the reservoir tank cap and strainer.
(b) Disconnect the connector.
(c) Check that no continuity exists between the terminals with
the switch OFF (float up).
(d) Use a siphon, etc. to take fluid out of the reservoir tank.
(e) Check that continuity exists between the terminals with
the switch ON (float down).
(f) Pour the fluid back in the reservoir tank.
If operation is not as specified, replace the switch.
20. INSPECT PARKING BRAKE WARNING SWITCH CON-
TINUITY
(a) Check that continuity exists between terminal and switch
body with the switch ON (switch pin released).
(b) Check that no continuity exists between terminal and
switch body with the switch OFF (switch pin pushed in).
If operation is not as specified, replace the switch or inspect
ground point.
21. INSPECT REAR LIGHTS WARNING LIGHT
(a) Disconnect the connector from the light failure sensor and
ground terminal 4 on the wire harness side connector.
(b) Start the engine, check that the warning light lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.

*: There is resistance because this circuit is grounded through
the bulb.
If the circuit is as specified, replace the sensor.
If the circuit is not as specified, inspect the circuits connected
to other parts.
23. INSPECT OPEN DOOR WARNING LIGHT
Disconnect the connector from the door courtesy switch, and
ground terminal 1 on the wire harness side connector and
check that the warning light lights up.
If the warning light does not light up, inspect the bulb or wire har-
ness.
24. INSPECT DOOR COURTESY SWITCH
(See page BE-31)
25. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the terminals buckle
switch and ground terminal on the wire harness side con-
nector as shown in the illustration.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, check the bulb circuit.
