5. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from battery to terminal 1
and negative (-) lead to terminal 2.
(b) Connect the positive (+) lead from tester to terminal 3 and
the negative (-) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0 V to 11
V or more between terminals 2 and 3.
HINT:
The voltage change should be 4 times for every revolution of
the speed sensor shaft.
If operation is not as specified, replace the sensor.
6. INSPECT SPEEDOMETER RESISTANCE
Measure the resistance between terminals with fixing pointer to
the stopper.
Tester connectionResistance (W)
A - B250
C - D250
If resistance value is not as the specified, replace the meter.
7. INSPECT TACHOMETER/ON-VEHICLE
(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.

15. INSPECT ENGINE COOLANT TEMPERATURE SEND-
ER GAUGE RESISTANCE
Connect the wire harness as shown in the illustration, and ad-
just the ammeter pointer to indicate º0º using the slide rheostat,
then read the rheostat indication.
Temperature °C (°F)Resistance (W)
50 (122.0)160 - 240
120 (248.0)17.1 - 21.2
If resistance value is not as specified, replace the engine cool-
ant sender gauge.
16. INSPECT LOW OIL PRESSURE WARNING LIGHT
(a) Disconnect the connector from the warning switch and
ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.
17. INSPECT LOW OIL PRESSURE WARNING SWITCH
OPERATION
(a) Check that continuity exists between the terminal and
ground with the engine stopped.
(b) Check that no continuity exists between the terminal and
ground with the engine running.
HINT:
Oil pressure should be over 29 kPa (0.35 kgf/cm
2, 4.3 psi)
If operation is not as specified, replace the switch.
18. INSPECT BRAKE WARNING LIGHT
(a) Disconnect the connector from the brake fluid warning
switch.
(b) Release the parking brake pedal.
(c) Connect the terminals on the wire harness side of the lev-
el warning switch connector.
(d) Start the engine, check that the warning light lights up.
If the warning light does not light up, test the bulb or wire har-
ness.

Mechanical check
Replace sliding roof motor with ECU. Perform forced operation.*
*: Holding the CLOSE/UP (OPEN/DOWN) switch pressed inhibits the jam protection function at approx.
10 sec. after starting the reverse operation.
If the switch remains pressed any longer, the sliding door starts close operation and it stops when
detecting the fully closed position.

ON-VEHICLE INSPECTION
1. OPERATING CHECK
(a) Depress the brake pedal several times with the engine off
and check that there is no change in the pedal reserve
distance.
(b) Depress the brake pedal and start the engine. If the pedal
goes down slightly, operation is normal.
2. AIR TIGHTNESS CHECK
(a) Start the engine and stop it after 1 or 2 minutes. Depress
the brake pedal several times slowly.
If the pedal goes down farthest the 1st time, but gradually rises
after the 2nd or 3rd time, the booster is air tight.
(b) Depress the brake pedal while the engine is running, and
stop the engine with the pedal depressed.
If there is no change in the pedal reverse travel after holding the
pedal for 30 seconds, the booster is air tight.

HINT:
Cancellation cannot be done by removing the battery cable or
ECU-IG fuse.
2. SPEED SENSOR SIGNAL CHECK (TEST MODE)
(a) Check the sensor signal.
(1) Using SST, connect terminals Ts and E
1 of DLC1.
SST 09843-18020
(2) Start the engine.
(3) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI-243).
(4) Drive vehicle straight forward.
(5) Drive vehicle at a speed faster than 45 km/h (28
mph) for several seconds.
HINT:
If the brake is applied during the check, the check routine must
be started again.
(6) Stop the vehicle.

1 of DLC1.
SST 09843-18020
(8) Read the number of blinks of the ABS warning light.
HINT:

See the list of DTC shown on the next page.

If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).

If 2 or more malfunction codes are identified at the same
time, the lowest numbered code will be displayed 1st.
