Abstract
A method of determining the electrical resistance of an actual harness connecting the Engine Control Unit (ECU) to a solenoid valve. The method includes providing a dummy harness connected at one end to the ECU and at the other end to a terminal connection in the vicinity of the solenoid valve. The method also includes determining the estimated RMS current through the actual harness and passing a current through the dummy harness such that the heat exchange to the environment is substantially the same as the actual harness. Power consumption of the dummy harness is measured and resistance of the actual harness is determined from estimated RMS and power consumption of the dummy harness.
