When the ECM receives a crank request, it energizes the starter relay in the EJB (engine junction box). The energized starter relay supplies 12 V power (fed via the 250 A megafuse in the BJB (battery junction box)) to energize the pull-in coil of the
starter solenoid. Once activated, the pull-in coil engages the solenoid plunger, which engages the pinion with the ring gear.
The plunger then closes the solenoid circuit, feeding power from the 400 A megafuse in the BJB to the starter motor.

Symptom Possible Causes Action Engine cranks too
slowly
Battery
Harness/Connectors
Starter motor
Oil grade Check the battery condition and state of charge. Check the starter
motor circuits. Refer to the electrical guides. Check the engine oil
grade and condition. Engine cranks too
fast
Low engine compression Check the engine compressions. Excessive starter
motor noise
Starter motor
Flywheel/Drive plate ring
gear
Starter motor
installation/casing Check the starter motor installation (fasteners tight, motor square to
engine, etc). Check the starter motor casing condition. Check the
flywheel/drive plate ring gear teeth for damage, foreign objects, etc. DTC Index

Engine Ignition - V8 5.0L Petrol/V8 S/C 5.0L Petrol - Engine Ignition - Overview
Description and Operation

OVERVIEW

The engine ignition system is a coil-on-plug, single spark system controlled by the ECM (engine control module). An iridium
tipped spark plug is installed in each combustion chamber, between the inlet and exhaust valves, and an ignition coil is
installed on each spark plug. A RFI (radio frequency interference) suppressor is connected to the power feed to the ignition
coils.

GENERAL System Operation

The ignition coils are supplied with electrical power from the battery via a 250 A megafuse in the BJB (battery junction box)
and the ignition relay in the EJB (engine junction box). The control signal for the ignition relay is supplied by the CJB (central
junction box).

The ECM (engine control module) sends a separate signal to each ignition coil to trigger the power stage switching. The ECM calculates the dwell time from the battery voltage and engine speed, to ensure a constant energy level is produced in the
secondary coil each time the power stage is switched. This ensures sufficient spark energy is available without excessive
primary current flow, which avoids overheating and damage to the ignition coils.
The ECM calculates the ignition timing for individual cylinders from: Engine speed
Camshaft position
Engine load
Engine temperature
The knock control function
The shift control function
The idle speed control function.



IGNITION COILS Component Description



The ignition coils are installed in the cylinder head covers, under the NVH (noise, vibration and harshness) covers. Each
ignition coil locates on a spark plug and is secured to the related cylinder head cover with a single screw. Each ignition coil
incorporates a three pin electrical connector for connection to the engine harness.

Each ignition coil contains a primary and a secondary winding. The primary winding receives electrical power from the ignition
relay in the power distribution box. A power stage in the primary winding allows the ECM to interrupt the power supply, to induce a voltage in the secondary winding and thus the spark plug. A diode in the ground side of the secondary winding
reduces any undesirable switch-on voltage, to prevent misfiring into the intake manifold. The power stage limits the maximum
voltage and current in the primary winding, to protect the power stage and limit the voltage in the secondary winding. www.JagDocs.com
