Distributor: Description and Operation
Ignition System Schematic
PURPOSE
The igniter physically fire the ignition coil in response to the ECU signal. Computers generally produce low amperage signals as outputs, much
lower than necessary to fire the coil.
LOCATION
Mounted to the left strut tower in the engine compartment.
CONSTRUCTION
The igniter consists of a power transistor and circuitry to provide a tachometer output.
OPERATION
The igniter is essentially an electronic relay. It receives a "trigger" from the ECU and responds by turning a higher amperage current to the ignition
coil on and off. Each time a spark is produced an ignition confirmation (IGF) signal is sent to the ECU.
