INSPECTION
1. INSPECT ROOM LIGHT ASSEMBLY CONTINUITY
(a) Disconnect the connector from room light assembly.
(b) Turn the room light switch ON, check that the there is con-
tinuity between terminal 2 and body ground.
(c) Turn the room light switch DOOR, check that there is con-
tinuity between terminals 1 and 2.
If operation is not as specified, replace the switch.
2. INSPECT DOOR COURTESY SWITCH CONTINUITY
(a) Check that there is no continuity between terminal and
the switch body in the ON position (switch pin released :
opened door).
(b) Check that there is continuity between terminal and the
switch body in the OFF position (switch pin pushed in :

3. INSPECT TACHOMETER ON−VEHICLE
(a) Connect a tune−up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside. When removing or instal-
ling the tachometer, be careful not to drop or subject it to
heavy shocks.
(b) Compare the tester and tachometer indications.
DC 13.5 V 20°C at (68°F)
Standard indication (rpm)Allowable range (rpm)
700610 − 750
3,0002,850 − 3,150
5,0004,850 − 5,150
7,0006,790 − 7,210
If error is excessive, replace the tachometer.
4. INSPECT VOLT GAUGE SYSTEM
Measure the resistance between terminals A and B.
Resistance: Approx. 347 Ω
If resistance value is not as specified, replace the gauge.
5. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 1 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 lights up
and the receiver gauge needle moves towards the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.

If resistance value is not as specified, replace the receiver
gauge.
7. INSPECT FUEL SENDER GAUGE OPERATION
(a) Connect a series of three 1.5 V dry batteries.
(b) Connect the positive (+) lead from the dry cell batteries to
terminal 2 through a 3.4 W test bulb and the negative (−)
lead to terminal 1.
(c) Check the positive (+) lead from the voltmeter to terminal
2 and the negative (−) lead to terminal 1.
(d) Check that the voltage rises as the float is moved from the
top to bottom position.
If operation is not as specified, replace the sender gauge.
8. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 1 and 2.
Float position (mm)Resistance (Ω)
F : Approx. 95.0F : Approx. 3.0
1 / 2 : Approx. 188.01 / 2 : Approx. 32.5
E : Approx. 283.0E : Approx. 110.0
If resistance value is not as specified, replace the sender
gauge.
9. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 4 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does no light up, test the bulb.

10. INSPECT FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminal 1 and 3,
and through a 3.4 W test bulb, check the bulb lights up.
HINT:
It will take a short time for bulb to light up.
(b) Submerge the switch in fuel, check that the bulb goes out.
If operation is not as specified, replace the sender gauge.
11. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates COOL.
(c) Ground terminal on the wire harness side connecter
through a 3.4 W test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and the receiver gauge needle moves to the hot side.
If operation is as specified, replace the sender gauge. Then, re-
check the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
