The Engine Control Unit, or ECU, in your vehicle is what monitors the different components of your engine and alerts you when something is malfunctioning or faulty. If your ECU, Power Control Module (PCM) or Fuel Injector Control Module (FICM) is faulty, it may alert you that something is wrong with your engine when it isn’t, and can cause a whole host of problems for your engine.
The IPC-certified technicians at My Auto Solutions take your faulty ECUs, PCMs and FICMs, and repair them within 24 hours so you can get back on the road safely.
