Mercedes Travego Engine ECU Repair

The owner of the Mercedes Travego 2014 Model EURO 5 Motor vehicle called our garage and reported a malfunction in the ECU. We have taken the TEMIC OM457 ECU to the desktop (Ecu Repair).


How is Mercedes Travego Engine ECU Repair Performed?


We made a connection between the ECU, which is the TEMIC OM457 belonging to Mercedes Travego, and the Ecutest Ecu Simulation and Test Device.

We made this connection with the Universal Socket, which is provided when you buy the Ecutest Ecu Simulation and Test Device, which allows you to easily connect to all heavy vehicle and passenger engine Ecu.

Upon the request of our customers, we can make it in the original socket of each engine Ecu, so you can connect the socket directly to the ECU and make your connection.

After we make our connection, we pain our simulation of the Ecutest Ecu Simulation and Test Device from the computer. After selecting the vehicle brand and model, we confirm the ECU TEMIC OM457 and enter our simulation screen.

When we run our simulation, we can see that the injectors are working smoothly both on the screen and on the device. Then we check the sensor supply voltages from the “Sensors Power” button on the left and see that it is OK.

When we check the sensors with the Ecutest Ecu Simulation and Test Device, which allows us to change the values of the PRESSURE-LEVEL-TEMPERATURE sensors on the right, we see that the “SCR Pressure Sensor” warns as a red light that it is defective.

We see that other sensors are working without any problems. With the Ecutest Ecu Simulation and Test Device, we quickly and easily detected the failure of the TEMIC OM457 ECU. We open the TEMIC OM457 inner schema by clicking the ‘Component Description’ button at the top of our simulation screen.

Here, we can see which integrated does what, its brand and model on the screen. We see that the SCR Pressure sensor is connected to the microprocessor.

By clicking ‘Electric Diagram’, we see the ECU pins connected to the SCR Pressure sensor. First of all, we check the path from the ECU pin to the circuit element with a multimeter. We see that there is a disconnection on the road and that it did not complete the circuit.

Then we complete this path with the help of a soldering iron. We test the TEMIC OM457 by connecting it to the Ecutest Ecu Simulation and Tester again and this time we see that the SCR Pressure Sensor is working without any problems.

Thus, with the Ecutest Ecu Simulation and Testing Device, we solve the TEMIC OM457 ECU of the Mercedes TRAVEGO EURO 5 vehicle quickly, easily and at minimum cost.
