The owner of the Mercedes Tourismo Euro 5 motor passenger bus called our garage and said that his vehicle had just changed Adblue, but it gave an Adblue problem on the screen (Mercedes Tourismo Ecu Repair).
We said we would help if he sent the ECU to us. Then we took the vehicle’s ECU to the desktop.
How to Repair Mercedes Tourismo ECU?
We are starting to examine the TEMIC OM457HLA ECU of the Mercedes Tourismo vehicle on the desktop. First of all, we make a connection between TEMIC OM457HLA and Ecutest Ecu Simulation and Test Device.
We made this connection with the Universal Socket, which is provided with the Ecutest Ecu Simulation and Test Device, allowing 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 making our connection, we open our simulation of the Ecutest Ecu Simulation and Test Device from the computer. After selecting the vehicle brand and model, we approve the ECU TEMIC OM457HLA and enter our simulation screen.
When we run our simulation screen, we first check the sensor supply voltages by clicking the “Sensors Powers” button on the left side of the screen. When we look at it, we see that it is unproblematic.
Later, we see that the “AdBlue Heater Valve” AdBlue Heater Valve, which appears in the middle of the screen, is defective and has malfunctioned in the red light.
Thus, we find the problem of TEMIC OM457HLA ECU. After finding the fault, we first see the internal diagram of the TEMIC OM457HLA ECU by clicking the “Component Description” button on our simulation screen.
Here it is written the role and brand of the circuit elements. Here we find the circuit element that controls the AdBlue Heater valve. Then, by clicking on ‘Electric Diagram’, we see the pin ends and signal types that the AdBlue Heater valve is connected.
Thus, thanks to the Ecutest Ecu Simulation and Test Device, we learn both the circuit element and the pin ends. Then we examine the integrated integrated with the help of a multimeter and see that there is no problem.
When we follow the path it is connected to from the ECU pins, we notice that there is a disconnection on the road. We repair the road without damaging the ECU. After this process is over, we connect the TEMIC OM457HLA Engine Ecu back to the Ecutest Ecu Simulation and Test Device.
We do our test on our simulation screen and observe that the problem has been resolved and the valves are working smoothly. Thus, thanks to the Ecutest Ecu Simulation and Test Device, we can solve the TEMIC OM457HLA ECU’s problem in the fastest, easiest and lowest cost. We deliver the TEMIC OM457HLA ECU to our customer.
