Rushjob Posted June 13, 2009 Share Posted June 13, 2009 I've got an amber ACE light on the dash. Checked it with Nanocom ( wonderful bit of kit! ) and it gave me two faults, first on was "the main relay was failing the test" - put a new on in & that's gone away but the second one is causing me a headache. The fault is "electrical circuit fault in the direction of control valve 2" I've checked and cleaned the contacts on the control valve itself, no change. I've checked the operation of the valave and can hear the Nanocom cycling it but I still have the amber lamp. Before I start to pull my motor apart, does anyone have any knowledge of further connections between the ECU and the valve or any further potential points to check - it's got me baffled as the valve works when the ECU and Nanocom asks it to.... .

cipx2 Posted June 15, 2009 Share Posted June 15, 2009 Try to switch the connectors on the valves between them for testing. See if the error moves with the valve or stays with the circuit. Quote Link to comment Share on other sites More sharing options...
