The electronic spark control module (ESC) is one of many components in your ignition system. Working alongside your distributor and ignition control module, the electronic spark control module varies ignition depending on many things like engine load. It signals the distributor to advance or retard timing. What does electronic control module do?
What does a spark control module do on a car?
The electronic spark control module is used by the vehicle’s engine to help control the ignition timing. It can improve the performance of the vehicle’s engine and make it run more efficiently. However, like any electronics, the spark control module in your car is bound to fail at least occasionally.
What is electronic spark control (ESC) system?
There are three basic components of the Electronic Spark Control (ESC) system. The Electronic Spark Control (ESC) sensor detects the presence (or absence) and intensity of the detonation by the vibration characteristics of the engine. The output is an electrical signal that goes to the controller. A sensor failure would allow no spark retard.
What does the ignition module do in a car?
The ignition module works together with the computer to time the engine’s ignition system for the best performance and efficiency. One of the specific functions of the ESC module is to advance or retard the timing of the ignition system, depending on the operation conditions.
How does the ECM and ESC work on a Ford Ranger?
It is connected to the ESC module which is mounted to the cowl in the engine compartment. In response to engine knock, the sensor sends a signal to the ESC module. The module will then signal the ECM which will retard the spark timing in the distributor. Electronic Spark Control General Information
What is the main purpose of a spark control system?
The ignition system is composed of parts and wirings that work together to create and distribute the voltage power needed by your spark plugs. This process creates the spark that raises the temperature in the air-fuel mixture, making it possible to start combustion.
What are the symptoms of a failing ignition module?
a faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough. the engine may also run well at low speed, but won't accelerate well. 3. stalling: a failing ignition module can occasionally prevent the engine from getting spark, causing it to stall.

What is electronic spark timing?
The spark-Optimizer is a closed-loop type electronic control device that continuously corrects the ignition timing; in effect it re-tunes the engine some ten times every second.

How long do ignition modules last?
around 100,000 milesAverage lifetime of ignition coil is around 100,000 miles or more. It is not an easy worn out replacement car part but still could fail for variety of reasons. #1. Coil insulation worn out due to aging.
How does an electronic module work?
Electronic control module: The component is also known as the control unit of an ignition system. it's what monitors and controls the timing and intensity of the spark automatically. The device receives voltage signals from the armature and set the primary coil on and off.
How does a ignition control module work?
Function of the ignition module The function is relatively straightforward. The ignition coil has a primary winding (small number of turns) and a secondary winding (lots of turns). The turn ratio between primary and secondary winding determines the level of the voltage generated at the output.

What does electronic spark advance do?
The electronic spark advance (ESA) system calculates duration for keeping the electric power on and the timing of ignition, and outputs an ignition signal depending on the crank angle. The ESA system detects the angular position of each cylinder based on the signal of the crank angle sensor.
How does ignition timing affect power?
The major benefit to advancing the timing of a vehicle's ignition is increasing the horsepower of an engine. Advancing the ignition timing helps raise the high-end power while reducing the low end. It also helps get the spark past the ignition delay and run at peak power.
What causes a code 42?
Ignition Bypass Circuit Error The ECM monitors the Ignition Bypass circuit and will set code 42 to signal an error. The ignition bypass circuit allows the ECM to switch the ignition module from "base" timing to computer-controlled timing advance.
How do you test an ignition module?

What can cause an ignition control module to fail?
The common cause of one driver/transistor failing is a shorted ignition coil primary winding. This is a winding of wire within the ignition coil where each loop is separated by a very thin plastic coating.
Does ignition module control fuel injectors?

What causes ignition module to burn out?
The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil's secondary winding.
What is the ECM?
The ECM is the center of a system, working with a host of sensors, actuators, connectors and wires. Sensors monitoring heat, voltage, movement, location, magnetic force and pressure measure everything from coolant temperature to cam position.
Can ECMs store trouble codes?
Luckily, ECMs store trouble codes that a technician can access with a scanner to point them in the right direction. The only problem is that ECMs don’t know the difference between a malfunctioning part and a malfunctioning sensor — all they get is input that something is wrong.
How to remove ESC module?
Typically located on the firewall, the ESC module may be located any number of places in the engine bay depending on application. Step 2: Disconnect the battery. Whenever working on your vehicle’s electrical or electronic systems, it’s a good idea to disconnect the battery. Always remove the negative battery cable and ...
How to clear ESC code?
Note: If your ESC set a fault code and illuminated your Check Engine Light, some vehicles will clear the code simply by the battery being disconnected. Other vehicles may require you to use a scan tool to clear the fault code. If you do not have one available, your local service facility or auto parts store may be able to do so for you.
What does a bad ESC module do?
Usually a bad or failing ESC module will produce a few symptoms that can alert the driver of a potential issue that should be serviced. 1. Engine performance issues.
What does it mean when your ESC module is not working?
Another common symptom of a faulty ESC module is a no start, or no spark condition. The ESC module is one of the components that directly controls engine spark, so if it fails, it can leave the vehicle without spark. A vehicle without spark may still crank, but will not be able to start or run.
How to tell if ESC module is bad?
Another symptom of a problematic ESC module is the engine stalling. A faulty module may cause the engine to suddenly stall and be unable to start again. Sometimes the engine can still be restarted after a short period of time, usually after the module has been allowed to cool off.
What are the symptoms of a bad ignition module?
1. Engine performance issues. One of the first symptoms of a problem with the ignition module are engine performance issues. If the ignition module fails or has any problems it can lead to performance issues with the vehicle, such as misfires, hesitation, loss of power, and even reduced fuel economy. 2.
Can a car start without spark?
A vehicle without spark may still crank, but will not be able to start or run. The ESC module is one of the most important components found on many modern ignition systems, and without it most vehicles will not run properly.
