What Is Electronic Spark Control Module Bypass? How To Do It?

The car’s engine uses the electronic spark control system to regulate the ignition’s spark timing. As a result, the car’s engine may operate more effectively and perform better.

However, your engine control module will eventually malfunction, just like any other electrical device.

So let’s learn in this article – electronic spark control module bypass and bad ignition module symptoms!

How To Conduct Electronic Spark Control Module Bypass

Electronic Spark Control Module Bypass

The electronic spark control module bypass feature enables compatibility with previous-generation GM electronic automobile ignition systems.

With this setup, the trigger signal goes straight to the ignitor module, which activates the engine ignition coil.

Let’s learn what you should prepare and how to bypass the ignition control module (especially the Ford ignition module)!

Preparing

Specifically, you’ll need the following:

  • An instrument with a flat head for driving screws
  • Equipment such as a voltmeter or a three-prong plug tester (optional)
  • Toolkit: soldering iron with non-acidic solder
  • Electronic components for severing wires
  • Car’s wiring harness or insulating tape made of electricity

You may use the multimeter to check the functionality of the electronic spark control module. For example, it can help you be confident that there is an issue with the electronic ignition system.

Otherwise, you may try fixing the issue by making the bypass adjustment and find that the problem wasn’t the ESC after all.

You shouldn’t retest the spark control module if you already know the issue. The changes may be made at this time.

How To Bypass Ignition Control Module

Here is how to disable the electronic spark control module in either automobile or truck.

  1. Open the hood of your vehicle.
  2. Find the car’s ignition distributor. Location suggestions include the bottom of the hood furthest from the engine. The canister-shaped ignition distributor is thick, with black engine spark plug wires atop the grey.
  3. Examine the four little wires, one each of green, white, brown, and black, located at the ignition distributor’s base. Your car’s electronic spark control module communicates with the ignition through those connections.
  4. Four inches from the ignition distributor, a male and female connection was attached to complete the four-wire electronic circuit for distribution.
  5. Unplug everything and take the male end of the connection from the computer’s spark module. Keep using the distributor’s female plug. Get hold of the green, white, brown, and black cables.
  6. Remove two to three inches of the green and black cables from the end of the connection.
  7. Solder and tape together the two stripped ends. You’ll need to trick the computer’s electrical circuit for distribution.
  8. You may also connect them without cutting or stripping, or soldering. Let’s buy an additional male connection when you don’t have solder or a wire remover. This connection is not intended to be structured cabling or used with automotive components. The female plug from the vehicle’s distributor must also be compatible with the connection.
  9. You’ll need only to line up the new male connection with the distributor-side female connectors. The next step is to determine which letters (A, B, C, or D) correspond to the green and black wires by inspecting the connections. For a guaranteed bypass of the electronic spark control module, there must be the correct combination of green and black.
  10.  Double-check your results after you’re confident in them. As long as your vehicle continues to operate normally after removing the ESC module, there’s no danger in checking again. Connect a jumper wire between the pins representing the green and back letters.
  11.  Remember to wrap the male connector onto the female distributor connector. After you’ve completed the loop, reattach the male end of the new connection to the female end. Cover the other plug to the ignitor’s electronic control module with tape.
  12.  You should be able to smell the gasoline and taste the starter. Even if it wasn’t lighting the first time, you could be comfortable that it would do so now. Still, there’s more to it than that. More work must be done to cut power to the ECS entirely. It’s not required, but it’s a nice touch.
  13.  Two colored wires, pink and orange, connect the battery to the distributors. The orange cable is connected to the electronic ignition system through the spark control module, whereas the pink one travels to the battery.

If you hadn’t noticed, the pink wire is much thicker than its orange counterpart. The pink cable must be unplugged. Then, pull the plug.

The electronic spark control module’s timing system cannot function with the computer removed.

That’s all; without the ESC, your driving circumstances may change. Thus, you may need to tweak your timing scheme. Again, the assistance of a trained technician is recommended for this modification.

What Things You Should Notice When Bypass Electronic Spark Control Module

You Need To Notice When Electronic Spark Control Module Bypass

The electronic spark control module in your automobile is responsible for coordinating the firing of the engine spark plugs. And multiple engine-wide sensors provide data into the control system.

These sensors include those that monitor the position of the camshaft, crankshaft, and throttle position, respectively.

Therefore, your car’s ESC module may not assist with ignition as intended if there is a breakdown in communication between these sensors.

Use An Aftermarket System

Bypassing the spark control module with an aftermarket electronic system is a frequent method of removing a malfunctioning module.

At the same time, the module may also be removed by cutting a few wires in the current circuit. Unfortunately, these strategies might backfire if not executed properly.

Put In An ESC Bypass Wire That Should Be As Short As Possible

It’s important to keep the ESC Bypass Cable as short as possible while adding one. This will reduce the chances of voltage drops and interference. 

Nevertheless, an open current circuit may occur during the preheating phase if it is too short. You can stretch the wire by two to three inches from where the plug enters the connection.

Use A Pair Of Wires That Are Twisted Together

Wiring your ESC bypass should be done with a twisted pair of cables for maximum safety. For example, you need a telephone cable or cord with four conductors, one for each telephone system.

To avoid overloading your bypass, only utilize one set of wires at a time.

Change The Ignition Timing Of Your Driving System.

You could have to alter the control of ignition timing of your electronic driving system after a complete bypass since the ESC won’t be there to detect any knocks in the engine.

So, you may need the module to change the control of ignition timing even though you don’t need it for the operation itself.

Consequently, the electronic spark control module may be found in various places depending on the make and type of the vehicle.

Regardless, most people put it in the back of the glove box, on the side facing the passenger. Simply pull down the glove box, and you’ll have access to everything you need.

The Symtoms Bad Ignition Control Module Symptoms

Excessive Heat

If there is a problem with the ignition module, it might cause the engine to overheat. 

An overheated ignition module may cause the car to sputter, emit a gasoline odor, and perhaps cause electrical shocks or smoke to pour out of the exhaust.

Simply driving the car or idling the engine will do a temperature test of the module.

The car won’t start because of a faulty ignition switch. Use ice water or a chiller if you need to lower the temperature. That, however, must be done until you can repair them.

Acceleration Problems

There is a possibility that the engine spark plugs in vehicles that are accelerating more slowly than usual are malfunctioning. An issue with the ignition is to blame for the jerky acceleration of your car.

Your vehicle’s engine could not obtain a spark from it that was sufficiently strong. When the accelerator is squeezed, there is a possibility of an action that is disorienting, vibrating, or shaking.

The reaction to an increase in engine speed may be resistance or insufficient force.

You will eventually lose all of your power, and you won’t be able to start your automobile. Injectors need to be investigated as a potential additional source of the problem.

One possible remedy involves changing the engine spark plugs and the ignition wires.

Hard Starting

Another sign is that the ignition spark is not present. Four elements must be in place to start and operate an internal combustion engine vehicle safely.

Exhaust, pressure, ignition, and fuel flow pump comprise combustion’s four stages. A jumbled input is to blame for a malfunctioning electronic ignition control.

As a result, checking the inputs again is a fast way to remedy the issue.

A major issue is that the car won’t turn over due to a broken ignition module. For some reason, the car won’t start either.

Hear a clicking noise when you press the key to ensure the engine ignition coil is working properly.

If the ignition control module fails, no electricity is generated, and hence no spark is created to potentially initiate combustion.

The Vehicle’s Warning System Will Activate

An issue with the ignition or the other component could be what the check engine light is trying to tell you about.

The check engine light will turn on if there is a problem with the vehicle.

This light will come on if the built-in diagnostic system finds that there is a possibility of an issue with the electronic ignition electrical circuit. 

There is also the possibility that difficulties with the electronic ignition system, like misfires, are to blame.

You may search for the issue by plugging a scan tool into your car’s On-Board Diagnostics (OBD) port and letting it do its thing. DTCs p0300–P0312 might be used to assist in the diagnosis of ignition issues.

If you do not have the appropriate tools, your best bet is to avoid attempting to diagnose the issue with your vehicle and instead bring it in for maintenance as soon as possible.

Rough Running

Inside an internal combustion engine, the symptoms of incomplete combustion often take the form of a misfire. In addition, the phrase “harsh engine” is sometimes used to refer to it.

With the igniter not working properly or other issues, the engine’s spark may be in peril. This might result in problems with the vehicle’s performance, such as misfires and a lack of power.

Even, it can happen while you are driving if your vehicle’s fuel-to-air ratio is wrong, resulting in the gasoline not igniting properly.

The number of faulty coils directly correlates to the severity of your problems while attempting to start the engine.

So, it is necessary to rule out the possibility that the engine’s inability to start was brought on by something other than the dead battery.

Here are five common bad ignition control module symptoms, and you can check further symptoms and how to check your spark control module in this writing.

FAQs

Let’s find out the answers to some quick questions.

Could The Absence Of A Spark Be The Result Of A Malfunctioning Ignition Control Module?

If the spark is weak, it indicates that the ignition control module is not operating as it should, and the vehicle will not start if it is not functioning correctly.

It is important to inspect the engine spark plug wires for any signs of damage and replace them if they are ragged or if there is corrosion on the switching or the terminals.

An ignition module that is not operating is yet another potential reason.

How To Bypass Ignition Coil?

Because the engine ignition coil is part of the electronic control module, you can follow guidelines on how to bypass the ignition control module to learn how to bypass the engine ignition coil.

If you are not a professional, let’s find a mechanic for helps.

What Is The Function of the Ignition Control Module And Electronic Spark Control Module?

There are a lot of older automobiles that have a separate ignition control module. The component is accountable for turning the engine ignition coil (or coils) on and off to light the engine spark plugs.

This is extremely important since the engine won’t function correctly until each engine spark plug is ignited at the precise moment specified by the manufacturer.

One vehicle module is the electronic spark control module (also known as the ignition module for short).

Its principal purpose is to modify the electronic spark timing according to the operation’s circumstances.

Conclusion

An electronic spark control module bypassing will take care of all of the module’s responsibilities.

Because it is integrated with the systems already in your vehicle, the bypass does not need the installation of any additional wiring.

Your car’s starting problems might be solved by installing a bypass for the electrical control module.

However, if you are unsure about how to bypass ignition control module on your own, you should seek the assistance of a qualified auto electrician or repair shop to ensure driving conditions.
