Computers, Sensors and Wires Oh My!

Modern Cars are Complicated Machines

Looking at a modern Car, Truck, or SUV can be mind boggling.  Most people know about Computers and Sensors in Cars. They everywhere and wires that run in all directions.  Not to mention modules and communication points. A lot of the technology is to keep us safe, others are to help ensure the vehicle is being properly maintained for a long service life.

Computers and Sensors in Cars

Modern cars have various sensors and modules that track and control different systems. Some examples include:

  • Engine control module (ECM): controls engine systems such as fuel injection and ignition.
  • Transmission control module (TCM): controls gear shifting and torque converter lock-up.
  • ABS control module: controls the anti-lock braking system.
  • Traction control module: controls the traction control system.
  • Suspension control module: controls the suspension height and stiffness.
  • Powertrain control module (PCM): controls the engine and transmission.
  • HVAC control module: controls the heating, ventilation, and air conditioning system.
  • Body control module (BCM): controls body systems like lighting and door locks.
  • Airbag control module: controls airbag deployment.
  • TPMS module: monitors tire pressure.
  • Lane departure warning module: monitors the vehicle’s position on the road.
  • ADAS modules: controls driver assistance features like braking and cruise control.

Vehicles are getting more and more complicated, pictured above is a steering rack or gear from a modern truck. Inside are complex electrical components receiving and sending signals to other parts of the vehicle. When servicing a vehicle knowing how to work with computers and sensors is critical. Our technicians attend industry training.  We know what is coming in the way of technology. All of these components combined for a working machine, should something stop working or disrupt the machine it must be repaired, find a good service center to help you along the way.
