Signs that You Need to Replace Your Your
Engine Control Module (ECM)
Most modern cars usually have an Engine
Control Module (ECM which is also referred to as an Engine Control Unit (ECU).
The unit is primarily responsible for drivability functions as well as engine
performance. In most cases the unit uses sensors and is able to calculate
engine spark and fuel so that the car performs well but it can have various
issues that may make the car undrivable and some of the signs that you need to
look out for are briefly highlighted below.
One of the way that you can be able to know
that your ECM has an issue is when the check light comes on. When the computer
detects a problem with the sensor or circuits then you are sure that the engine
check light will go on. If you see the light make sure that you check the car
for potential issues and especially issues that relate to your cummins ecm.
Erratic engine behaviour is another sign
that you are having problem with your ECM and it is something that you need to
check on. Stalling or misfires are common problems that you may be able to see
when your computer is faulty. In most cases such issues may come and go and they
are also likely to have a pattern or severity.
If you are having engine performance issues
then it is something else that you need to look ino as well since it indicates
that you have problem with your diesel ecm.
Fuel settings and timing can easily be affected when you have issues with ECM
and it can negatively impact the performance of the vehicle. When the ECM is
faulty, you will have problems with power, acceleration and even reduction in
fuel efficiency and although a proper diagnosis needs to be done so that you
are sure that the problem is with the ECM unit it is important to rule out
other issues first.
Something else that can alert you that you
have bad ECM is if your car refuses to start or if you have difficulty in
starting your car. Incase the ECM is completely faulty you will have problems
completely with the engine management control since the engine will refuse to
start completely. As much as the engine will crank up you are sure that it will
not be able to start without the vital inputs of the computer and this will
mean that you may need to get a new ECM unit.
