Electronic Control Unit OPEL – ISUZU 7540015/1
We often receive complains about ECU 7540015/1. The complaint is that the ECU stops working and needs replacement.
We would like to clarify that the problem is not due to manufacturing origin photos from web pages. It is instead caused by overstressing the components inside the ECU.
Let us see two of the most frequent cases:
- ECU contaminated with diesel fuel: This occurs because this control unit is positioned directly below the injection pump 파일쿠키 다운로드. The pressure regulator on the pump, due to strong thermal stress and high load, loses a plastic part and this causes a leakage. Diesel drops pass into the pressure regulator connector and proceed through the cover of the cable to the control unit, filling it with diesel 실키픽스 다운로드.
- Overheated ECU or subjected to vibrations: again because of its position (in a very hot area of the engine bay), the ECU could be accidentally damaged by overheating 메리와마녀의꽃 다운로드. The result will be a failure of the inner welding, causing the ECU to malfunction.
To avoid these problems, we recommend you to follow these steps before proceeding with the replacement of the ECU:
- Control the pressure regulator of the fuel pump. Fuel must not enter the electric wiring in any case. If there is a leakage, replace the pressure regulator on the injection pump. Dry the wiring and connections waterproofing them with silicone in order to avoid a recurrence of the trouble.
- If you need to replace the control unit, find a new place to avoid overheating and vibrations. Vibrations combined with heat will cause the rupture of internal welds. If possible, isolate the ECU with rubber vibration dampers. If you decide to change the position of the ECU, you may need to lengthen the wiring.
