IGNITION SYSTEM

SERVICE TOOLS
Description
ECM ADAPTER TOOL...................................................................
FLUKE 115 MULTIMETER ............................................................
GENERAL
SYSTEM DESCRIPTION
The battery supplies the primary side of ignition
coils 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 Engine Management System (EMS) controls
the ignition system. For more information, refer
ENGINE MANAGEMENT
to
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 AND FAULT CODES
step. Refer to
subsection.
WIRING DIAGRAM
Always refer to the
troubleshooting an electrical circuit.
Refer to POWER DISTRIBUTION AND GROUNDS
for fuse and relay information.
WIRING HARNESS AND CONNECTORS
Refer to
for vehicle wiring harness layout and component
locations.
