INSPECTION
1. INSPECT VEHICLE SPEED SENSOR OPERATION
Check that there is continuity between terminals A and B four
times for every revolution of the speedometer shaft.
If operation is not as specified, replace the speedometer.
2. INSPECT FUEL RECEIVER GAUGE OPERATION

(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 5 and 6 on the wire harness side con-
nector 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 towards the full
side.

2 and the negative (-) lead to terminal 4.
(b) Connect the positive (+) lead from the battery to terminal
6 through a 3.4 W tester bulb.
(c) Push the defogger switch ON, check that the indicator
light and test bulb light up for 12 to 18 minutes, then the
indicator light and test bulb lights go out.
If operation is not as specified, replace the switch.

6. INSPECT DEFOGGER WIRE
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires. Do not use detergents or glass cleaners with
abrasive ingredients. When measuring voltage, wind a
piece of tin foil around the top of the negative probe and
press the foil against the wire with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5 VOkay (No break in wire)
Approx.10 V or 0 VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
positive (+) terminal.
(e) Place the voltmeter negative (-) lead with the foil strip
against the heat wire at the positive (+) terminal end and
slide it toward the negative (-) terminal end.
(f) The point where the voltmeter deflects from zero to sever-
al V is the place where the heat wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe is moved to the other end.
