Things You Should Know About Auto Computer & Modules
What Are Auto Computer & Modules?
Modern cars are highly advanced and complex pieces of
technology. The majority of the car’s functions are controlled by its engine
computer, also known as its Engine Control Unit
(ECU), Engine Control Modules (ECM), or Powertrain Control Modules (PCM). These
computers process loads of information and can execute a host of functions. In the
vehicle, the engine computer monitors or controls a multitude of processes that
keeps it running at its optimal level. It’s able to adapt to changing
conditions and the driver’s own driving patterns to ensure the car is
functioning as efficiently and safely as possible.
Types Of Auto Computer & Modules
Car's today can have as many as 50 different computer
systems in them. These computer systems control a huge number of things in the
car including Engine controls to meet emissions standards. Types of ECU include
engine control module (ECM), Powertrain Control Modules (PCM), Transmission
Control Modules (TCM), Brake Control Modules (BCM or EBCM), Central Control
Modules (CCM), Central Timing Modules (CTM), General Electronic Modules (GEM),
Body Control Modules (BCM), Suspension Control Modules (SCM), control unit, or
control module. Taken together, these systems are sometimes referred to as the
car's computer, technically there is no single computer but multiple ones.
Sometimes one assembly incorporates several of the individual control modules
PCM is often both engine and transmission.
Important Features Of Auto Computer & Modules
ECM's start-up procedure is to calibrate the position of
the throttle at idle. The ECM also makes sure the car meets emissions
standards, by monitoring and regulating the fuel mixture. The ECM has a
microprocessor that receives, interprets and reacts to sensor inputs as fast as
they occur. ECM can be customized to fit the automotive manufacturer's
specifications. ECU ensures that the vehicle operates at optimal performance.
How Does Auto Computer & Modules Work?
The engine control module basically controls the
intersection of the engine’s necessary ingredients to make energy fuel, air and
spark. But the ECM accomplishes its considerable chore by constantly monitoring
a vast network of sensors around the car to ensure conditions are within normal
operating range. When something goes wrong, the ECM adjusts conditions or, if
it can't, the car won't run properly or at all. When there's a problem, the ECM
stores a trouble code so it can be diagnosed by a mechanic and triggers the
check engine light so the driver knows something's wrong. The car’s engine
computer basically monitors and controls all essential vehicle functions
keeping tabs on everything and making sure it’s all running smoothly. It is
constantly receiving information from a variety sensors positioned throughout
the engine so it can do things like: Regulate fuel injectors,
Control the spark plugs, Adapt the idle speed, Notify the driver of a problem
with the Check Engine light, Monitor the ignition system, Deliver electrical
commands to the transmission and camshaft systems. The computer is able to
monitor these functions with information from the oxygen sensor, air pressure
sensor, air temperature sensor, throttle position sensor, and the knock sensor,
among others all to get the best performance possible out of the engine while
keeping emissions low.
Frequent Problems With Auto Computer & Modules
Corrosion or damage due to moisture is one of the main
reasons for ECM failure. Corrosion can enter the ECM through the wiring harness
and moisture can enter by a failure in the seals in the ECM itself. The
electronic fuel solenoid is also the main reason for failure in the ECM. The
solenoid can cause a short in the ECM due to corrosion in the solenoid or the
wire running from the solenoid to the ECM harness. Another issue that can cause
failure in the ECM is poor grounding. This can be the result of loose or
corroded ground wires to the battery or the frame. Arc welding on the frame can
blow out the ECM as well as lightning strikes. If the vehicle has been
jump-started recently and the cables were connected improperly this can cause a
spike in the ECM and cause it to short out. If there is any problem in the ECU.
The car becomes jerky when driving at increasing speeds. Misfiring of the car
at high speeds. The pick-up of the car, when accelerating, is not smooth.

It is very important to arm yourself with information before you shop any auto part. We are here to help you dive deep into the names of the Auto Computer & Modules related parts.
Total Cost And Repair Time For Auto Computer & Modules
For replacing Auto Computer & Modules, labor would
cost about $150 to $200, depending on the type of vehicle. To remove the Auto
Computer & Modules, other related parts have to be removed first and after
fitting of the ECU programming has to be done which may take about 1 to 2 hours
depending on the type of vehicle.
How To Change Auto Computer & Modules?
Open the engine compartment to access the battery.
Disconnect the battery with a socket wrench. Locate the ECM either in the
engine compartment or under one of the front seats in the vehicle. The ECM is a
silver, rectangular module. Disconnect the electrical supply by lifting the
locking tab and pulling away from the computer. This will isolate the
electrical power. Unbolt the screws holding the ECM in place with a socket
wrench. Pull the old ECM out and replace it with the new one. Bolt the ECM in
place with the socket wrench. Ensure the bolts are tight. Plugin the electrical
wires to the ECM. The wiring harness will lock in once it is pushed in far
enough. Connect the battery cables to the battery. Tighten the cables with a
socket wrench. Start the vehicle and allow it to idle for five minutes. If
there is a programming error, the check engine light will come on.
