ECU Electronic control unit -ADA 304

Teaching Experimental Applications (View Specification (docx) )

  • Analysis of how the electronic injection control unit works on an ECU- Motor.
  • Analysis of the ECU input signals.
  • Analysis of the ECU output signals.
  • Testing electrical/electronic signals with without voltage and under voltage.
  • Handling of auto-diagnosis tools: DD-Car.
  • Fault Diagnosis: Broken sensor, failure in the communication bus (CAN-LIN), etc.
  • Testing of sensors and actuators using an auto-diagnosis tool.
  • Instrumentation handling: Oscilloscope, Polymeter

Technical Details

  • Stand-alone equipment that incorporates the simulation of the following sensors and actuators:
  • SENSORS: Air mass senor, air admission temperature, crankshaft position, camshaft position, accelerator pedal position, coolant temperature, wide band Lambda sensor, absolute pressure sensor and vibration sensor.
  • ACTUATORS: Gas injectors, gas valves, spark plugs, Turbo electro valve and MAL (Malfunction Indicator Lamp).
  • Sensor and actuator communication with the ECU by different types of signal; analogue, digital, multiplexing buses CAN and LIN.
  • Testing points protected against possible incorrect manipulations, for carrying out measurements at the different points of the circuit.
  • Possibility of generating malfunctions in the signal sent by the sensors to the ECU.
  • Automatic or individual operation of the sensors (AUT/IND)
  • Reprogramming function (Flash) of the ECU as a Turbo motor or Atmospheric.
  • Auto-diagnosis function implemented in the ECU.
  • Possibility of disconnecting the sensors/actuators simulated in the panel and of connecting the real sensors/ actuators


DD-Car is a Diagnosis Teaching Tool prepared  to work with the panel. Working with DD-Car will allow the student to become familiar with the operation of auto-diagnosis consoles on the market allowing their adaptation to any of them to be quicker and easier, in addition testing can be carried out without the risk entailed on working directly on the systems of the vehicles.

The following functions can be made:

  • Reading and deleting the breakdown code.
  • Reading of values and analysis in real time of the operation of the system.
  • Activation of the actuators.
  • ECU Programming (flash)
  • Carrying out basic adjustments in the system.

Contents to be studied
