What is the schematic of an electronic ignition system?
A schematic diagram of an electronic ignition system is shown in Figure 2.36. It consist of a battery, ignition switch, electronic control unit, magnetic pick-up, reluctor or armature, ignition coil, distributor and spark plugs. The construction of battery, ignition switch. ignition coil, distributor and spark plug is similar to previous methods.
How is a contact point ignition system different from an electronic ignition system?
The basic difference between contact point’ and electronic ignition systems is in the primary circuit. In the contact breaker system, the primary circuit is opened and closed by the electronic control unit shown in Figure 2.35.
What is the role of ignition control module?
It is used to ON and OFF the primary current. The ignition control module performs the same operation as that contact point performs in another ignition system. It manages the dwell period (remains in a given state) on its own. It plays an important role in generating the magnetic field.
How does a contact breaker work in an ignition system?
In the contact breaker system, the primary circuit is opened and closed by the electronic control unit shown in Figure 2.35. The secondary circuits are practically similar to previous systems. In the secondary circuit, the distributor, ignition coil, and wiring are altered to handle the higher voltage that the electronic ignition system produces.
What are the signs of a faulty ignition switch?

Can a fault code be retrieved when the ignition is off?
This scanner should still retrieve fault codes when the ignition is off. If you don’t have this scanner or know of a shop that does, a possible alternative would be to use iCarsoft MB II scanner. The only issue here is that if you can’t turn on the ignition, you can’t power on the OBD2 port and the iCarsoft MB II scanner.
What causes a bad ignition switch on a Mercedes Benz?
This issue is often caused either by a defective key, bad shifter module, a failed Electronic Ignition Switch (EIS) also known as the EIS-EZS or a bad steering lock module (ESL). This problem can affect various Mercedes-Benz models including E-Class, S-Class, C-Class, CLK-Class, ML-Class, SL-Class, etc.
