An Electronic Control Unit (ECU) is any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle.

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).

Some modern motor vehicles have up to 80 ECUs. Embedded software in ECUs continues to increase in line count, complexity, and sophistication. Managing the increasing complexity and number of ECUs in a vehicle has become a key challenge for car repair garages and requires dealer level diagnostic tools.

Types of ECU include:

  • Engine Control Module (ECM)
  • Powertrain Control Module (PCM)
  • Transmission Control Module (TCM)
  • Braking System Modules (ABS, EPB, TCS, ESP)
  • Central Control Module (CCM)
  • General Electronic Module (GEM)
  • Body Control Module (BCM)
  • Suspension Control Module (SCM)
  • Immobiliser Module (IMMO)

Plus many more...

What are the signs of a faulty ECU?

  • Check Engine light comes one.
  • Engine stalling or misfiring.
  • Poor or inconsistent engine performance
  • Car not starting.
