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.

12. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 3 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 not light up, test the bulb or inspect wire
harness.
13. 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 connector
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 toward the hot
side.
If operation is as specified, replace the sender gauge.
Then recheck the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
14. INSPECT ENGINE COOLANT TEMPERATURE RE-
CEIVER GAUGE 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 specified, replace the receiver
gauge.

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.

19. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
OPERATION
(a) Remove the reservoir tank cap and strainer.
(b) Disconnect the connector.
(c) Check that no continuity exists between the terminals with
the switch OFF (float up).
(d) Use a siphon, etc. to take fluid out of the reservoir tank.
(e) Check that continuity exists between the terminals with
the switch ON (float down).
(f) Pour the fluid back in the reservoir tank.
If operation is not as specified, replace the switch.
20. INSPECT PARKING BRAKE WARNING SWITCH CON-
TINUITY
(a) Check that continuity exists between terminal and switch
body with the switch ON (switch pin released).
(b) Check that no continuity exists between terminal and
switch body with the switch OFF (switch pin pushed in).
If operation is not as specified, replace the switch or inspect
ground point.
21. INSPECT REAR LIGHTS WARNING LIGHT
(a) Disconnect the connector from the light failure sensor and
ground terminal 4 on the wire harness side connector.
(b) Start the engine, check that the warning light lights up.
If the warning light does not light up, test the bulb or inspect wire
harness.

REGISTRATION PROCEDURE
1. KEY REGISTRATION IN AUTOMATIC REGISTRATION MODE
(a) Registration of a new transponder key.
HINT:

This must be done when you have installed a new ECM.

The new ECM is in the automatic key code registration mode. The already fixed number of key codes
for this ECM can be registered.
On this type of vehicle, up to 4 key codes can be registered.

In the automatic registration mode, the last key registered becomes sub-key.

HINT:

When a key is not inserted in the key cylinder in the automatic registration mode, the security indicator
always lights on.

When the immobiliser system operations normally and the key is pull out, the security indicator blinks.

When key code registration could not be performed in the automatic registration mode, code 2-1 is
output from the security indicator and when inserting the already registered key, code 2-2 is output.
(b) Automatic registration mode completion
If completing the mode forcibly when more than 1 key code have been registered in the automatic reg-
istration mode, perform the following procedures.
After 1 more key code have been registered with master key, perform step (1) or (2) without pulling
the key out or inserting the already registered key.
(1) Depress and release brake pedal 5 times or more within 15 secs.
(2) With the hand-held tester, require automatic registration mode completion.
