ON-VEHICLE SERVICE
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

7. Connect a tachometer or the MUT-II/III (Refer to
GROUP 11A − On-vehicle Service − Idle speed
check <4G1> P.11A-11 or GROUP 11C −
On-vehicle Service − Idle speed check <4G6>
P.11C-11).
8. Leave the hood open.
9. Check that the reading on the voltmeter is equal
to the battery voltage.
NOTE: If the voltage is 0 V, the cause is probably
an open circuit in the wire or fusible link between
the alternator "B" terminal and the battery (+)
terminal.
10.Turn the light switch on to turn on headlamps and
then start the engine.
11.Immediately after setting the headlamps to high
beam and turning the heater blower switch to the
high revolution position, increase the engine
speed to 2,500 r/min and read the maximum
current output value displayed on the ammeter.
Limit: 70 % of normal current outputNOTE: .
•For the nominal current output, refer to the
Alternator Specifications.
•Because the current from the battery will soon
drop after the engine is started, the above step
should be carried out as quickly as possible in
order to obtain the maximum current output
value.
•The current output value will depend on the
electrical load and the temperature of the
alternator body.
•If the electrical load is small while testing, the
specified level of current may not be output
even though the alternator is normal. In such
cases, increase the electrical load by leaving
the headlamps turned on for some time to
discharge the battery or by using the lighting
system in another vehicle, and then test again.
•The specified level of current also may not be
output if the temperature of the alternator body
or the ambient temperature is too high. In such
cases, cool the alternator and then test again.
12.The reading on the ammeter should be above the
limit value. If the reading is below the limit value
and the alternator output wire is normal, remove
the alternator from the engine and check the
alternator.
13.Run the engine at idle after the test.
14.Turn the ignition switch to the "LOCK" (OFF)
position.
15.Remove the tachometer or the MUT-II/III.
16.Disconnect the negative battery cable.
17.Disconnect the ammeter and voltmeter.
18.Connect the negative battery cable.

DOOR MIRROR OPERATION
Remote Controlled Mirror Operation
•The mirror on the door mirror moves up/down
and left/right by operating the remote controlled
door mirror switch when the ignition switch is in
the "ON" or "ACC" position.Heated Door Mirror operation
•The defogger relay switch is activated (ON) by
turning on the A/C-ECU built-in defogger switch
when the ignition switch is in the "ON" position.
When the defogger relay is turned ON, power is
supplied to the defogger and door mirror, and the
heater of the door mirror (heated door mirror)
starts operations. The defogger comes with a
timer function and will automatically turn OFF the
switch approximately 11 minutes after the
defogger switch is turned ON. The heated door
mirror operations are also terminated along with
the defogger, at this time.

COMMENTS ON TROUBLE SYMPTOM
The heated door mirrors should works for
approximately 11 minutes when the rear defogger
switch is turned on. If the mirror heater does not work
for the specified period, the defogger relay circuit
(heated door mirror power supply circuit) may be
defective.
Possible causes
•Damaged harness wires and connectors
DIAGNOSIS PROCEDURE
STEP 1. Check the rear window defogger.
Check that the rear window defogger system should
work normally.
Q: Is the check result normal?
YES :
Go to Step 2.
NO : Troubleshoot the rear window defogger
(Refer to GROUP 55,
TroubleshootingP.55-42).
STEP 2. Connector check: C-212 junction block
connector
Q: Is the check result normal?
YES :
Intermittent malfunction (Refer to GROUP
00 − How to Cope with Intermittent
Malfunction P.00-5).
NO : Repair the defective connector.
