and opening calculated by ECM (PCM) (Obtained on the basis of
engine speed and intake manifold pressure) in larger than specified
value.
2 driving cycle detection logic, continuous monitoring

High resistance in the circuit

ECM (PCM) malfunction
DTC CONFIRMATION PROCEDURE
WARNING:

When performing a road test, select a place where there is no traffic or possibility of a traffic accident
and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and a tester, on a level road.
1) Turn ignition switch OFF. Clear DTC with ignition switch ON, check vehicle and environmental condition for:
–Indication of fuel level meter in combination meter: 1 / 4 or more
–Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
–Intake air temp.: between –10C and 80C (14F and 176F)
–Engine coolant temp.: 70C, 158F or higher
2) Warm up engine to normal operating temperature.
3) Increase vehicle speed to 30 – 40 mph, 50 – 60 km / h in 3rd gear or “D” range and hold throttle valve at that
opening position for 1 min.
4) Stop vehicle.
5) Check DTC in “DTC” mode and pending DTC in “ON BOARD TEST” or “PENDING DTC” mode.

and be very careful during testing to avoid occurrence of an accident.

Road test should be carried out with 2 persons, a driver and tester, on a level road.
1) Turn ignition switch OFF.
Clear DTC with ignition switch ON, check vehicle and environmental condition for:
–Altitude (barometric pressure): 2400 m, 8000 ft or less (560 mmHg, 75 kPa or more)
–Intake air temp.: between –10C and 80C (14F and 158F)
–Engine coolant temp.: 70C, 230F or higher
2) Start engine and drive vehicle at 41 – 46 mph, 65 – 75 km / h for 8 min. or longer.
While this driving, if “Catalyst Monitoring TEST COMPLETED” is displayed in “READINESS TESTS” mode and
DTC is not displayed in “DTC” mode, confirmation test is completed.
If “TEST NOT COMPLTD” is still being displayed, continue test driving.
3) Decrease vehicle speed at 28 – 34 mph, 45 – 55 km / h, and hold throttle valve at that opening position for 2 min.
and confirm that short term fuel trim vary within –20% –+20% range.
4) Stop vehicle (do not turn ignition switch OFF) and confirm test results according to following “Test Result Con-
firmation Flow Table”.

INSTALLATION
1) Lift engine with transmission into engine compartment, but do
not remove support device.
2) Install engine right mounting to right mounting bracket and stiff-
ener.
3) Install engine left mounting to body.
4) Install rear mounting to body (For M/T model)
Install torque rod (For A/T model)
5) Tighten bolts and nuts of all parts installed in above steps 2),
3) and 4) or 5) to specified torque.
Tightening Torque
(a): 55 N
.m (5.5 kg-m, 40.0 lb-ft)
6) Remove support device.
7) Reverse removal procedures for installation of remainder.

Push in each drive shaft joint fully so that snap ring engages
with differential gear or center bearing support.
Use care not to damage oil seal lip when inserting.

Clamp electric wire securely.
8) Adjust clutch pedal free travel by referring to Section 7C. (M / T)
Adjust gear select cable and A / T throttle pressure control
cable, referring to Section 7B. (A / T)
9) Adjust gear shift control lever by referring to Section 7A. (M / T)
10) Adjust accelerator cable play by referring to Section 6E.
11) Refill transmission with gear oil. (A / T fluid for A / T model) by
referring to Section 0B.
12) Refill engine with engine oil by referring to Section 0B.
13) Refill cooling system by referring to Section 6B.
14) Adjust A / C compressor and / or P / S pump drive belt referring
to Section 0B. (if equipped)
15) Check P / S fluid level by referring to Section 3B1. (if equipped)
16) Upon completion of installation, verify that there is no fuel leak-
age, coolant leakage, transmission oil leakage or exhaust gas
leakage at each connection.

6B-6 ENGINE COOLING
COOLING SYSTEM FLUSH AND REFILL
WARNING:
To help avoid danger of being burned, do not remove radia-
tor cap while engine and radiator cap while engine and ra-
diator are still hot. Scalding fluid and steam can be blown
out under pressure if cap is taken off too soon.
1) Remove radiator cap when engine is cool:
Turn cap counterclockwise slowly until it reaches a “stop”.
(Do not press down while turning it.)
Wait until pressure is relieved (indicated by a hissing sound)
then press down on cap and continue to turn it counterclock-
wise.
2) With radiator cap removed, run engine until upper radiator
hose is hot (this shows that thermostat is open and coolant is
flowing through system).
3) Stop engine and open radiator drain plug (1) to drain coolant.
4) Close drain plug. Add water until system is filled and run engine
until upper radiator hose is hot again.
5) Repeat Steps 3) and 4) several times until drained liquid is
nearly colorless.
6) Drain system and then close radiator drain plug tightly.
7) Disconnect reservoir tank hose from radiator. Remove reser-
voir tank and pour out any fluid. Scrub and clean inside of tank
with soap and water.
Flush it well with clean water and drain. Reinstall tank and
hose.
8) add 50 / 50 mixture of GOLDEN CRUISER 1200 (Good quality
ethylene glycol anti-freeze) and water to radiator and tank.
Fill radiator to the base of radiator filler neck and reservoir tank
to “FULL” level mark. Reinstall reservoir tank cap.
9) Run engine, with radiator cap removed, until radiator upper
hose is hot.
10) With engine idling, add coolant to radiator until level reaches
the bottom of filler neck. Install radiator cap, making sure that
the ear of cap lines up with reservoir tank hose.
