Customer advised that the vehicle is not revving and although the car starts, he is unable to drive it. After diagnostics, they suspected an ECU fault and sent it to us for testing and repairs.
We have purpose built simulation test rigs to independently test ECU’s and simulate the full functionality of ECU’s as if the unit was fitted and running on the vehicle.
We tested this ECU and found that the ECU was only giving 0.6volts to the TPS (Throttle Position Sensor) when it should be sending 5volts. We also found that the Ambient Pressure Sensor was sending 1013 bar pressure through the ECU but the ECU was recording only 800 bar pressure.
We re-worked the board and repaired the ECU (replacing faulty components for new genuine parts). The ECU then passed a 2nd time on our ECU Testing rig and was sent back to the customer fully working with 12 months warranty.
