IGNITION SYSTEM

SERVICE TOOLS

Description
ECM ADAPTER TOOL...................................................................
FLUKE 115 MULTIMETER ............................................................
GENERAL
SYSTEM DESCRIPTION
The battery supplies the primary side of ignition
coil through the main relay (R2) while the ECM
completes the circuit for each cylinder by switch-
ing it to ground at the right moment. The ECM
can detect an open and short circuit in the primary
winding but it does not check the secondary wind-
ing.
The EMS controls the ignition system. For more
information, refer to
subsection.
Ignition Timing
Ignition timing is not adjustable.

TROUBLESHOOTING

It is good practice to check for fault codes using
the B.U.D.S. software as a first troubleshooting
DIAGNOSTIC SYSTEM AND FAULT
step. Refer to
CODES
subsection.
WIRING DIAGRAM
Always refer to the
troubleshooting an electrical circuit.
Refer to POWER DISTRIBUTION AND GROUNDS
for fuse and relay information.
