5.4L & 6.8L IGNITION DESCRIPTION
This single-fire Ignition is intended to operate with 
a 10-cylinder, 6.8L engine and an 8-cylinder, 5.4L 
engine.
The 6.8L engine uses a 40-1 crank sensor, a mag-
pickup CAM sensor and individual coil-on-plug coils 
for each spark-plug.
The 5.4L engine uses a 36-1 crank sensor, a mag-
pick-up CAM sensor and individual coil-on-plug coils 
for each spark-plug. 
With a single-fire ignition, each high-voltage coil out-
put is connected to one spark plug resulting in that 
spark plug being fired only during the compression 
cycle.

engine is:

 IGNITION POWER-UP INPUT ("56 LINE 
INPUT")
When battery voltage is applied to this input the igni-
tion will power-up. For the ignition to power itself 
down, battery voltage must be removed from this 
input.
IGNITION ENABLE ("14 LINE INPUT")
This input must be connected to the +12V battery for 
the ignition to turn-on the coils.  If this input is con-
nected to battery ground the ignition will stop firing 
the coils and will power down within approximately 
2 seconds.  In the event that an ignition fault has 
occurred, however, the ignition will wait 60 seconds 
before powering down.  This allows time to view the 
diagnostic LED located on the ignition board.

NOTE:
The ignition cover does not need to be removed to 
see the LED.
 IGNITION SHUTDOWN ON LOSS OF CRANK 
OR CAM SIGNALS
The ignition will stop firing the coils immediately fol-
lowing the loss of the crank signal.  The ignition will 
stop firing the coils after approx. 3 seconds following 
the loss of the cam signal.
 DIAGNOSTIC BLINK PATTERNS (RED LED 
LOCATED ON THE IGNITION CONTROL 
BOARD)
During normal ignition operation the RED LED 
flashes at a 0.5 sec ON and a 0.5 sec OFF rate.  This 
is considered one (1) blink.
LED Fault Code with Priority as shown:
1.  No Crank Signal:  LED blinks 2 times, is OFF for 
3.0 seconds and then repeats
2.  No CAM Signal:  LED blinks 3 times, is OFF for 
3.0 seconds and then repeats 
Only one fault is displayed at a time. If multiple faults 
exist then the highest priority fault must be resolved 
prior to a lower priority fault being displayed. In the 
event that an ignition fault has occurred the ignition 
will wait 60 seconds before powering down.
NOTE:
The ignition cover does not need to be removed to 
see the LED.
