INSPECTION
1. INSPECT SPEEDOMETER ON–VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.

If error is excessive, replace the speedometer.
2. 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 the voltage changes from approx. 0 V to 11 V
or more between terminals 2 and 3.
HINT:
The voltage changes be 4 times every revolution of the speed
sensor shaft.
If operation is not as specified, replace the sensor.
3. 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.

4. 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 recheck the system.
If operation is not as specified, measure the receiver gauge re-
sistance.
5. 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 and check that the warning
light lights up.
If the warning light does not light up, test the bulb.

6. INSPECT LOW OIL PRESSURE SWITCH CONTINUITY
(a) Disconnect the connector from the switch.
(b) Check that continuity exists between terminal and ground
with the engine stopped.
(c) Check that no continuity exists between terminal and
ground with the engine running.
HINT:
Oil pressure should be over 24.5 kPa (0.25 kgf/cm
2, 3.55 psi).
If operation is not as specified, replace the switch.

DRIVE BELT (1CD–FTV)
ON–VEHICLE INSPECTION
1. INSPECT DRIVE BELT INSTALLATION CONDITION
Check that the drive belt fits properily in the ribbed grooves.
2. INSPECT DRIVE BELT DEFLECTION
Using a belt tension gauge, apply load of 98 N (10 kgf, 22 lbf)
and measure drive belt deflection.
Drive belt deflection:
New belt: 11 – 13 mm (0.47 – 0.51 in.)
Used belt: 15 – 18 mm (0.59 – 0.71 in.)
HINT:

”New belt” refers to a belt which has been used less than
5 minutes on the running engine.

”Used belt” refer to a belt which has been on a running en-
gine for 5 minutes or more.

After installing the drive belt, check that it fits properly in
the ribbed grooves.
3. INSPECT DRIVE BELT TENSION
Using a belt tension gauge, check the drive belt tension.
Drive belt tension:
New belt: 520 – 755 N (53 – 77 kgf)
Used belt: 196 – 392 N (20 – 40 kgf)

ON–VEHICLE INSPECTION
NOTICE:

If the glow plug breaks, the ECU detects the breakage and stops the automatic operation, so
the burner heater does not activate. (For other failures, similarly activated.)

The cause of failures (such as voltage malfunction, overheating malfunction, short–circuit or
breakage of functional componects, etc.) and how to remedy are shown by connecting the DTC
tester and reading the DTC.
1. OPERATION
(a) Connect the DTC tester between the connector A (Vehicle harness) of DTC check harness and con-
nector B (Power heater harness).
(b) Start the engine.
(c) Pressing the DTC calling button displays a 3–digit number DTC.
