ENGINE COOLANT LEAK CHECKM1141001000300
WARNING
When pressure testing the cooling system,
slowly release cooling system pressure to
avoid getting burned by hot coolant.
CAUTION
•Be sure to completely clean away any
moisture from the places checked.
•When the tester is taken out, be careful not to
spill any coolant.
•Be careful when installing and removing the
tester and when testing not to deform the
filler neck of the radiator.
1. Check that the coolant level is up to the filler neck.
Install a radiator tester and apply 160 kPa
pressure, and then check for leakage from the
radiator hose or connections.
2. If there is leakage, repair or replace the
appropriate part.
RADIATOR CAP VALVE OPENING
PRESSURE CHECK
M1141001300389
NOTE: Be sure that the cap is clean before
testing. Rust or other foreign material on the cap
seal will cause an improper reading.
1. Use a cap adapter to attach the cap to the tester.2. Increase the pressure until the indicator of the
gauge stops moving.
Minimum limit: 83 kPa
Standard value: 93 − 123 kPa
3. Replace the radiator cap if the reading does not
remain at or above the limit.
ENGINE COOLANT REPLACEMENTM1141001200434
WARNING
When removing the radiator cap, use care to
avoid contact with hot coolant or steam.
Place a shop towel over the cap and turn the
cap counterclockwise a little to let the
pressure escape through the vinyl tube.
After relieving the steam pressure, remove
the cap by slowly turning it
counterclockwise.
1. Drain the water from the radiator, heater core and
engine after unplugging the radiator drain plug
and removing the radiator cap.
2. Drain the water in the water jacket by unplugging
the drain plug of the cylinder block.
3. Remove the radiator condenser tank and drain
the coolant.
4. Drain the coolant then clean the path of the
coolant by injecting water into the radiator from
the radiator cap area.

CHARGING SYSTEM
ENGINE ELECTRICAL16-5
OUTPUT CURRENT TESTM1161001000368
This test determines whether the alternator output
current is normal.
1. Before the test, always be sure to check the
following.
•Alternator installation
•Battery (Refer to GROUP 54A − Battery −
On-vehicle Service P.54A-5).
NOTE: The battery should be slightly discharged.
The load needed by a fully-charged battery is
insufficient for an accurate test.
•Drive belt tension
(Refer to GROUP 11A − On-vehicle Service <4G1>
P.11A-7 or GROUP 11C − On-vehicle Service
<4G6> P.11C-7.)
•Fusible link
•Abnormal noise from the alternator while the
engine is running.
2. Turn the ignition switch to the "LOCK" (OFF)
position.
3. Disconnect the negative battery cable.CAUTION
Never use clips but tighten bolts and nuts to
connect the line. Otherwise loose connections
(e.g. using clips) will lead to a serious accident
because of high current.
4. Connect a clamp-type DC test ammeter with a
range of 0 − 120 A to the alternator "B" terminal
output wire.
NOTE: The way of disconnecting the alternator
output wire and of connecting the ammeter is
possibly not found the problem that the output
current is dropping due to the insufficient
connection between terminal "B" and the output
wire.
5. Connect a voltmeter with a range of 0 − 20 V
between the alternator "B" terminal and the earth
[Connect the (+) lead of the voltmeter to the "B"
terminal, and then connect the (-) lead of the
voltmeter to the earth].
6. Connect the negative battery cable.

NOTE: For information on tyre inflation pressure,
refer to the label attached to the centre pillar on the
driver's side.
TYRE WEAR CHECKM1311001000334
Measure the tread depth of the tyres.
Minimum limit: 1.6 mm
If the remaining tread depth is less than the minimum
limit, replace the tyre.
NOTE: When the tread depth of the tyres is reduced
to 1.6 mm or less, wear indicators will appear.
WHEEL RUNOUT CHECKM1311001100353
Jack up the vehicle so that the wheels are clear of
the floor. While slowly turning the wheel, measure
wheel runout with a dial indicator.
Limit:
If wheel runout exceeds the limit, replace the wheel.

COMBINATION METER ASSEMBLY
CHASSIS ELECTRICAL54A-60
STEP 9. Check the wiring harness between
combination meter connector C-04 (terminal 1
and 2) and earth.
Q: Are the wiring harness between combination meter
connector C-04 (terminal 1 and 2) and earth in
good condition?
YES :
This procedure is complete.
NO : Repair or replace the wiring harness. Check
to see that all meters operate.

SPEEDOMETER CHECKM1543000900423
Adjust the pressure of tyres to the specified level.
(Refer to GROUP 31, On-vehicle Service P.31-7.)
CAUTION
Do not operate the clutch suddenly. Do not
increase/decrease speed rapidly while testing.
1. Set the vehicle onto a speedometer tester and
use wheel chocks to hold the rear wheels.2. To prevent the front wheel from moving from side
to side, attach tension bars to the tie-down hook,
and secure both ends to anchor plates.
3. To prevent the vehicle from moving, attach a chain
or wire to the rear retraction hook, and make sure
the end of the chain or wire is secured.
4. Check if the speedometer indicator range is within
the standard values.
Standard value:
5. If not to the standard value, inspect for proper tyre
size. If not correct, replace the tyres with original
size tyres and retest. If correct, replace the
speedometer. If still not to standard value, replace
the vehicle speed sensor.
TACHOMETER CHECKM1543001000434
1. Attach an external high quality tachometer to the
engine speed detection connector on the harness
side (such as with a paper clip).
