(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.
SST 09843±18020
(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.

(1) Be sure that fuel is enough in tank.
(2) Turn ignition switch on.
(3) Using SST, connect terminals FP and + B of
data link connector 1.

Check for fuel pressure in the return hose when it
is pinched off.
Disconnect the high±tension cord from the distributor and, hold the end about 12.5 mm (1/2º)
from the ground, see if spark occurs while the engine is being cranked.
To prevent excessive fuel injected from the injectors during this test, don't crank the engine for
more than 1±2 seconds at a time.Never make a mistake with the terminal con±
nection position as this will cause a malfunc±
tion.

Check fuel pressure.
Check for spark.
At this time, you will hear fuel return noise.
