Jeep Grand Cherokee ECU Repair

The JEEP Grand Cherokee all-terrain vehicle owner called our garage and reported that there was a problem with the vehicle ECU. We asked him to send his Ecu to us and we asked him if there was a mechanical breakdown in the vehicle(Jeep Grand Ecu Repair).

Our customer stated that there was no mechanical problem, although the oil level was normal in the vehicle, but it gave an oil failure.


How to Repair JEEP Grand Cherokee ECU?


We took the BOSCH EDC15C5 ECU of the JEEP Grand Cherokee off-road vehicle to the desktop. We made a connection between BOSCH EDC15C5 and Ecutest Ecu Simulation and Tester.

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 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 confirm the ECU BOSCH EDC15C5 and enter our simulation screen.

Later, when we checked the sensors on the right side of our simulation screen, we observed that the “Oil Pressure Sensor” in the “Pressure Sensor” category was defective and gave us a warning at the red light.

When we look at our other sensors, we see that there is no problem even though we change their values. Then, we open the BOSCH EDC15C5 inner diagram 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 find the circuit element to which the Oil Pressure Sensor is connected. Then click on ‘Electric Diagram’ and see the pins connected to the Fuel Temperature Sensor.

Then, with the help of a multimeter, we first check the path of the pins. When we follow the path where the pins are connected to the integral, we detect the disconnection in the path with the help of the Multimeter.

These road disconnections can be invisible to the eye. Using a multimeter for this is the healthiest method. Then we complete our way with the help of a soldering iron, we solve our problem.

For testing, we reconnect the BOSCH EDC15C5 ECU to the Ecutest Ecu Simulation and Test Device. When we turn our simulation screen back on, when we check the sensors, we see that the problem has been resolved and the other sensors work normally.

Thus, thanks to the Ecutest Ecu Simulation and Testing Device, we can solve the problem of the BOSCH EDC15C5 ECU of the JEEP Grand Cherokee off-road vehicle quickly, easily and with minimum cost.
