What happens when a Distributorless Ignition module fails?
These pulses are then delivered to the spark plugs either via a distributor cap, rotor, and spark plug wires, or directly (in the case of distributorless ignition systems.) When an ignition module fails, the engine will not start or run.
What do you need to replace an ignition module?
Replacing an ignition module is a simple bolt-on type repair, but you may need to clean the mating surface and apply some dielectric grease. When this is necessary, you will typically find a tube of the appropriate material in the box that your replacement ignition module comes in.
Why does the ignition module fire the spark plugs?
This is due to the fact that the ignition module is responsible for activating the ignition coil, which itself is responsible for firing the spark plugs.
How does an ignition module work in a transistor?
Ignition modules are solid state switching devices that typically use a component like a transistor to switch the current flow through the primary winding of an ignition coil on and off. In that way, an ignition module works a lot like mechanical points.
How does the ECM control the ignition coil?
The ECM controls the igniter at Start Up and at all engine speeds after Start Up, unlike the majority of distributor-type ignition systems where the ignition control module freelances at Start Up. Here are a few suggestions to help you to diagnose your Honda’s ignition system free of headaches and/or complications:
How does the ignition coil accord igniter work?
The distributor shaft starts to turn (as the engine cranks and starts) which induces the Position Sensors to start producing and sending their position signals to the ECM ( E lectronic C ontrol M odule=Fuel Injection Computer). Upon receiving these position signals, the ECM sends a Triggering Signal to pulse the igniter.
What does the switching signal on an ignition coil mean?
The Switching Signal is just the ‘switching’ ON and OFF of the primary current flowing thru’ the Coil by interrupting its path to Ground. The primary current is just the name for the 12 Volts that the ignition coil receives.
What is the primary current of the igniter?
The primary current is just the name for the 12 Volts that the ignition coil receives. The ECM controls the igniter at Start Up and at all engine speeds after Start Up, unlike the majority of distributor-type ignition systems where the ignition control module freelances at Start Up.
