INSPECTION
1. INSPECT SPEEDOMETER ON±VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check odometer operation.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.

If error is excessive, replace the speedometer.
2. INSPECT TACHOMETER
(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.

(c) Connect terminals 2 and 3 on the wire harness side con-
nector through a 3.4 watts test bulb.
(d) Turn the ignition switch ON, check that the bulb comes on
and the receiver gauge needle moves towards the full
side.
HINT:
Because of silicon oil in the gauge, it will take a short time for
the needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
4. INSPECT FUEL LEVEL WARNING LIGHT OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 2 and 3 on the wire harness side con-
nector.
(c) Turn the ignition switch ON and check that the warning
light comes on.
If the warning light does not come on, test the bulb or inspect
the wire harness.
5. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
(a) Disconnect the engine coolant temperature sender
gauge.
(b) Measure the resistance between terminals 1 and 2 of the
connector according to the value(s) in the table below.
Temperature °C (°F)Resistance (W)
±20 (±4)13,840 to 16,330
20 (68)2,320 to 2,590
80 (176)310 to 326
110 (230)139.9 to 143.5
If resistance value is not as specified, replace the engine cool-
ant sender gauge.
6. INSPECT OIL PRESSURE SENDER OPERATION
(a) Disconnect the connector from the oil pressure sender.
(b) Check that no continuity exists between terminal and
ground with the engine stopped.
(c) Check that continuity exists between terminal and ground
with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the oil pressure sender.

on.
If the warning light does not come on, test the bulb or wire har-
ness.
8. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
CONTINUITY
(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 siphon, etc. to drain 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 continuity is not as specified, replace the switch.
9. INSPECT PARKING BRAKE SWITCH CONTINUITY
(a) Check that continuity exists between the terminal and
switch body with the switch ON (switch pin released).
(b) Check that no continuity exists between the 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.
10. INSPECT WASHER LEVEL WARNING LIGHT OPERA-
TION
(a) Disconnect the connectors from the combination meter.
(b) Connect the negative (±) lead from the battery to terminal
16.
