ignition module problems symptoms.Modern vehicles are equipped with a variety of sensors and electronic modules to control the various engine functions required for the vehicle to operate.
Ignition Module Problems Symptoms
One of these components is the electronic spark control module, commonly referred to as the ESC module, or the ignition module. The ignition module works in conjunction with the computer to time the engine ignition system for optimum performance and efficiency. One of the specific functions of the ESC module is to advance or delay the timing of the ignition system, depending on the operating conditions.
Under heavy load, the module will advance the timing to increase power and delay it at low acceleration and cruise speeds to maximize efficiency. The ESC module makes these changes automatically and smoothly, almost to the point where they are almost imperceptible to the driver. As the ESC module plays an important role in engine operation, any problem with it can cause problems with the driveability and performance of the vehicle. Typically, a bad or defective ESC module will produce some symptoms that can alert the driver to a potential problem that must be addressed.
1. Engine performance problems

One of the first symptoms of a problem with the ignition module is engine performance problems. If the ignition module fails or has any problems, it can lead to vehicle performance problems such as misfire, hesitation, power loss and even reduced fuel economy.
2. Engine shutdown
Another symptom of a problematic ESC module is the motor stop. A faulty module can cause the motor to stop suddenly and cannot start again. Sometimes the motor can still be restarted after a short period of time, usually after the module has been allowed to cool down.
3. 3. no-start car or spark-free engine
Another common symptom of a faulty ESC module is a no start or spark condition. The ESC module is one of the components that directly controls the engine spark, so if it fails, you can leave the vehicle spark-free. A spark-free vehicle can still start, but will not be able to start or run.
The ESC module is one of the most important components found in many modern ignition systems, and without it most vehicles will not function properly. If you suspect that your ESC module may be having a problem, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine if your vehicle needs a replacement of the electronic spark control.
