Where is the ignition module located?
Where is the ignition module located? The location of the ignition module depends on where the vehicle was manufactured. In a domestic model, the module sits on, inside, or near the distributor housing. Foreign models will hide their ignitor within the vehicle’s firewall or wheel-well.
What happens when ignition control module goes bad?
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 causes an ignition module to go bad?
The number one reason that ignition modules go bad is because of heat. On most of the cars that have a recurring problem with this, they have the original distributor in the car. As the distributor ages and wears, the bushing in the shaft goes goes bad and starts to cause excessive heat.
What is the ignition control module?
The Ignition Control Module is a part of the ignition system. It manages the electrical current that is fed to the ignition coil in order for it to generate the right amount of voltage for the spark-plug to ignite the fuel mixture. In turn, the ignition control module sends the input to the ignition coil to fire it up.
What does the ECM do on a 1992 Chevy truck?
The 1992 Chevy truck has an electronic control module (ECM) that governs the engine management systems. It’s a little computer that performs routine systems checks; if it encounters a malfunction in any of the systems, it generates a diagnostic trouble code. The ECM stores this code in memory and turns on the truck’s Check Engine light.
Where do I find the ignition module on my car?
Use a wiring diagram for the year model of your vehicle. Locate the terminals running into and out of the ignition module. Placement of the module varies from model to model so check the appropiate service manual of your vehicle for the exact location.
Are there ways to test a GM Hei module?
Are there ways to test a GM HEI module? The easiest way to test a module on the car is to ensure that the wiring & pickup coil are OK. The module is essentially an amplifier with a built in analog to digital convertor. 1. Test for power at the pink BAT terminal. You should have battery voltage w/ the key in the start and RUN positions. 2.

How do you reset the ECM on a Chevy?
Step 2: Wait around 5 to 10 minutes. Let residual power be drained out of the vehicle. This will wipe the ECM memory. Step 3: Re-attach the disconnected cables to the battery. This will reset the ECM. Step 1: Read your vehicle manual.
On some cars, the ignition module may be housed on or inside the distributor. In other cases, it may be a standalone unit, or it may be integrated into the ignition coil assembly. The ignition module is easy to access and replace on some vehicles, but on others, it’s buried deep inside the engine compartment.
What happens if you have a bad ignition control module?
A faulty ignition control module can cause a number of problems. 1. Check engine light is on: The ECM monitors all parts of the vehicle that could affect emissions. This includes the ignition system. If it determines the ignition module has caused a problem with the system, it will turn on the check engine light.
How does the ECM control the ignition module?
On most vehicles built within the last few decades, the sensor’s signal is sent first to the ECM. The ECM then uses this information to control ignition module operation. On some vehicles, the ECM may control ignition timing above a certain engine RPM, while the ignition module has control below a certain RPM.
What is the role of the ignition coil?
Its two main roles are to create a spark strong enough to ignite the air/fuel mixture for combustion and to control the timing of the spark plugs by opening and closing the ignition coil ground circuit.
How to tell if you have a bad ignition control module?
If it determines the ignition module has caused a problem with the system, it will turn on the check engine light. 2. Engine is misfiring or running rough: An engine misfire results from incomplete combustion. A faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough.
