There
are some important modules on which our vehicles life and performance depends.
As we know every part plays its own function to make the vehicle run smoothly
but the major part is that their working depends on each other also.
Sometimes
your car has some electrical system flaws which are not easily identified and
the problem assumed to be mechanical, like engine noise or problems with the
engine running smoothly. So it might be because your car is having some issue
in its ECM, and needs some attention.
Engine Control Module is
a very important part for your car because if this part is working properly
then don’t worry about paying for car tuning. The main purpose of engine
control module is to elicit an ideal performance for vehicles and make overall
working smooth.
Body Control Module is
one another important part of the car, and also known as body computer. It is
responsible for controlling and monitoring various electronic accessories in a
vehicle's body. Mainly the body control module controls the central locking,
air conditioning, power windows etc. For example, a BCM of another vehicle will
not open the doors when you use your key or remote. It communicates with all
the other modules via the cars vehicle bus, also drives all the relays and the
control all the nice gadgets. BCM can do additional checks like locking the
doors to prevent the thief from leaving.
The
Ignition Control Module controls the ignition coil that is why it is known as the heart of
automobile’s ignition systems. The main working of ignition control module is
to produce a high voltage that can be sent to spark plug. Also, it is located
near the insulating compounds. To increase the life of ICM transistor is
attached to heat sinks which dissipate heat better than any other attachment
method.
Transmission Control Module acts as a hub for information gathered by various sensors. The TCM reads this
data and communicates with the transmission to determine accurate gear shifting
to create a smooth driving experience. This module runs for long periods
without major problems and if some kind of issue occurs in transmission control
module then you can fix it yourself, it just needs fluid drain or cleaning.
Also, this works for wide range of vehicles.
