GENERAL
Ignition System Testing Sequence
In the case of ignition problems, check the follow-
ing in the prescribed order until the problem can
be solved.
1) Fault codes.
2) Spark testing.
3) Ignition coil.
4) DESS post.
5) Engine cut-out switch.
6) Crankshaft Position Sensor (CPS).
Analysis of Readings
• Resistance Readings
Place multimeter selector switch to
in order to
measure resistance. Readings must be within the
indicated range. Otherwise, the part is consid-
ered to be defective and must be replaced.
CAUTION: When taking measurements, it is
useless to try to start the vehicle since readings
would then be distorted.
• Intermittent Ignition Problems
It is difficult to make a diagnostic in the case of in-
termittent ignition problems. Thus, problems oc-
curring only when the engine operating tempera-
ture is normal must be checked in similar condi-
tions.
Using the Vehicle Communication Kit (VCK)
(P/N 529 035 981) and B.U.D.S. software, verify
which fault codes occurred. Refer to ENGINE
MANAGEMENT for complete list of codes.
Spark Testing
B.U.D.S.canbeusedtoperformthistest. Con-
nect the VCK and go to the ACTIVATION folder.
A manual test can be performed too. Do the fol-
lowing.
During this operation, it is important to use the
snowmobile spark plug and not a new one. Bring
theplugincontactwiththeengine. Pullrewind
starter. If no spark is produced, replace the spark
plug with a new one and do the test again.
For more information on spark plug condition, re-
fer to SPARK PLUG further in this section.
Ignition Coil
Disconnect ignition coil connector.
Compare readings with those appearing in the IG-
NITION COIL table.
