3. INSPECT SPEEDOMETER VOLTAGE
(a) While driving the vehicle at the speed of 10 km/h, check
the voltage between the terminals 16 and 1 of the com-
bination meter assy.
STANDARD: Fluctuation between 10 to 14 V or less is
repeated 7 times within 1 sec.
4. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from the tester to terminal
3 and the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be performed 4 times for every rev-
olution is not as specified, replace the sensor.
5. INSPECT TACHOMETER / ON-VEHICLE
(a) Connect a tune-up test tachometer, and start the engine.
(b) Compare the tester and tachometer indications.
DC 13.5 V 25 °C at (77°F):

3. INSPECT ENGINE ROOM R/B RELAY CIRCUIT (See
Pase BE-15)
HINT:
The mirror heater relay is built in engine room junction block.
Also the relay is constructed with a relay block that is in the junc-
tion block as a unit. To disconnect the wire harness connecting
with relay block is impossible. If the relay has a malfunction, re-
place it with junction block assembly wire harness together.
4. 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 in-
gredients.
When measuring voltage, wrap a piece of tin foil around the
tip 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. 5VOkay (No break in wire)
Approx. 10V or 0VBroken 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
wire on the battery side.
(e) Place the voltmeter negative (-) lead with the foil strip
against the wire on the ground side.
(f) Slide the positive (+) lead from battery to ground side.
(g) The point where the voltmeter deflects from several V to
zero V is the place where the defogger 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 voltage gradually increases
to about 12 V as the meter probe moves to the other end.
