(b) Apply a light coat of engine oil on the threads and
under the head of the relief valve.
(c) Temporarily install the oil cooler with the nut.
(d) Install the plate washer and relief valve.

OIL COOLER INSPECTION
1. INSPECT RELIEF VALVE
Push the valve with a wooden stick to check if it is
stuck.
If stuck, replace the relief valve.
OIL COOLER INSTALLATION
(See Components for Removal and Installation)
1. INSTALL OIL COOLER
(a) Install new O±ring and gasket to the oil cooler. 4. REMOVE OIL COOLER
(a) Remove the relief valve and plate washer.
(b) Remove the nut and oil cooler.
(c) Remove the O±ring and gasket from the oil cooler.
2. INSPECT OIL COOLER
Check the oil cooler for damage or clogging.

BASIC INSPECTION
When the normal code is displayed in the diagnostic trouble code check, troubleshooting should be
performed in the order for all possible circuits to be considered as the causes of the problems.
In many cases, by carrying out the basic engine check shown in the following flow chart, the location
causing the problem can be found quickly and efficiently. Therefore, use of this check is essential in en-
gine troubleshooting.
Remove air filter.
Visually check that the air filter is not excessively
damaged or oily.
If necessary, clean the air filter with compressed
air. First blow from inside thoroughly, then blow
off outside of the air filter.
Is battery positive voltage 11 V or more when engine is stopped?
Proceed to matrix chart of problem
symptoms on page EG1±327.
Is engine cranked ?
Does engine start
Charge or replace battery.

(1) Shift transmission into ªNº position or neutral.
(2) Warm up engine at normal operating temperature.
(3) Keep the engine speed at idle.
(4) Using SST, connect terminals TE1 and E1 of
data link connector 1.

(5) Using a timing light, connect the tester to
No. 1 high±tension cord.(1) Shift transmission into ªNº position or neutral.
(2) Warm up engine at normal operating temperature.
(3) Switched off all accessories.
(4) Switched off air conditioning.
(5) Connect tachometer test probe to terminal
IG (±) of data link connector 1, and set the
tachometer to the 4±cylinder range.
wNEVER allow tachometer test probe to touch
ground as it could result in damage to igniter
and/or ignition coil.
wAs some tachometers are not compatible
with this ignition system, we recommended
that you confirm compatibility of your unit
before use.

CIRCUIT DESCRIPTION
The distributor in the Engine Control System contains 3 pickup coils.
The G signals inform the ECM of the standard crankshaft position.
The NE signals inform the ECM of the crankshaft position and the engine speed.
wDuring cranking or idling, check waveforms
between terminals G (+) and G (±),
NE (+) and NE (±) of engine control module.
HINT: The correct waveforms appear as shown
in the illustration on the left.
wOpen or short in NE, G circuit
wDistributor
wOpen or short in STA circuit
wECM No G signal to ECM for 3 sec. or more with
engine speed between 600 rpm and 4,000 rpm. No N E signal to ECM with 2 sec. or more after
cranking.
