IGNITION SYSTEM TESTING
NOTE: It is a good practice to check for fault
codes using B.U.D.S. software as a first trou-
bleshooting step. Refer to
COMMUNICATION
TOOLS AND B.U.D.S. SOFTWARE
subsection.
If a primary winding of an ignition coil or a circuit
is at fault, a fault code will be set. Refer to
MON-
ITORING SYSTEM AND FAULT CODES
subsec-
tion.
Ignition System Testing Sequence
Ensure fuses 7, 8 and 9 (in fuse box #1) are good.
If a fuse is burnt, test for a short circuit or faulty
component on that fuse circuit before replacing
the fuse.
WARNING
Due to the possibility of flammable vapors ac-
cumulating in the bilge, you should always
test for a short circuit which may produce a
spark and ignite the vapors before replacing
a burnt fuse.
If one cylinder is not firing and there is no fault
code, replace each spark plug with a known good
spark plug until the faulty plug is located.
If the fault is not found, carry out an
IGNITION
COIL QUICK TEST USING B.U.D.S.
PROCEDURES
IGNITION COILS
WARNING
Never check for engine ignition spark from
an open coil and/or spark plug in the engine
compartment as a spark may cause fuel va-
pors which may have accumulated in the
bilge to ignite.
Ignition Coil Test Using B.U.D.S.
Open seat.
Remove rear ventilation box. Refer to
AIR INTAKE
SYSTEM
.
Connect to the latest applicable B.U.D.S. soft-
ware. Refer to
COMMUNICATION TOOLS AND
B.U.D.S. SOFTWARE
section.
In B.U.D.S., select the Activation tab and the
ECM tab.
Energize the desired ignition coil by selecting it on
the engine illustration.
