(d) Turn the ignition switch ON, and 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.
6. INSPECT FUEL RECEIVER GAUGE RESISTANCE

7. INSPECT FUEL SENDER GAUGE OPERATION
(a) Connect a series of three 1.5 V dry cell batteries.
(b) Connect the positive (+) lead from the dry cell batteries to
terminal 4 through a 3.4 W test bulb and the negative ( −)
lead to terminal 5.
(c) Connect the positive (+) lead from the voltmeter to termi- nal 4 and the negative ( −) lead to terminal 5.
(d) Check that the voltage rises as the float is moved from the
full to empty position.
8. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 4 and 5.
Float position: mm (in.)Resistance (Ω )
F: Approx. 15.0 (0.591)Approx. 3.0
E: Approx. 200.0 (7.874)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 5 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
10. INSPECT FUEL LEVEL WARNING SWITCH
(a) Apply battery positive voltage between terminals 1 and 5
through a 3.4 W test bulb, and check that the bulb lights
up.
HINT:
It will take a short time for the bulb to light up.
(b) Submerge the switch in fuel, and 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, and check that the receiver
gauge needle indicates COOL.
(c) Ground terminal on the wire harness side connector through a 3.4 W test bulb.
(d) Turn the ignition switch ON, and 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.
12. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
Between terminalsResistance (Ω )
A − B71 − 79
A − C117 − 141
B − C185 − 215
HINT:
Connect the test leads so that the current from the ohmmeter
can flow according to the above order. This circuit include the
diode.
If resistance value is not as specified, replace the receiver
gauge.
13. INSPECT OIL PRESSURE RECEIVER GAUGE OP-
ERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, and check that the receiver
gauge needle indicates LOW.

(c) Ground terminal on the wire harness side through a 3.4
W test bulb.
(d) Turn the ignition switch ON, and check that the bulb lights
up and that the receiver gauge needle moves to the high
side.
If operation is not as specified, measure the receiver gauge re-
sistance.
14. INSPECT OIL PRESSURE RECEIVER GAUGE RESIS- TANCE
Measure the receiver gauge resistance between terminals. Resistance:
40 − 48 Ω
If resistance value is not as specified, replace the receiver
gauge.
15. INSPECT OIL PRESSURE SENDER GAUGE OPERA-
TION
(a) Disconnect the connector from the sender gauge.
(b) Apply battery positive voltage to the sender gauge termi- nal through a test LED.
(c) Check that the bulb does not light when the engine is stopped.
(d) Check that the LED flashes when the engine is running. The number of flashed should vary with engine speed.
If operation is not as specified, replace the sender gauge.
16. INSPECT BRAKE WARNING LIGHT
(a) Disconnect the connectors from the level warning switch and parking brake switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Turn the ignition switch ON, and check that the warning light lights up.
17. INSPECT PARKING BRAKE SWITCH
(a) Check that there is continuity between terminal and the switch set nut with switch pin released (parking brake le-
ver pulled up).
(b) Check that there is no continuity between terminal and the switch set nut with switch pin pushed in. (parking
brake lever released)
If operation is not as specified, replace the switch.
