Hello again, thank you for that -

The looms are known for chaffing and breaking inside - what you need to have checked is the loom for continuity - the best way to do this is to have diagnostic equipment on it as you have arranged -

That is the quickest and most cost effective way because it will tell straightway what circuit is affected - (usually engine management ) and ID the area of loom quickly that way - then it has to be manually traced / stripped to find and cure the fault.

Sometimes, its just bad connection - solder connections do suffer on these I have seen several - but that is the quickest way to do this / find and cure it, if it cant be found manually.

I assume its been checked manually already - but if not, it needs to be checked very carefully, twisting the loom over and round especially where it runs near metal parts of the engine - they are favorite for chaffing, rubbing through on metal parts and splitting the wires causing what you have -and other faults too as it progresses..

So work through as above on this one now progressing to the diagnostic if needed.

Another very common issue on this model is for the Ecu ( engine management computer ) to develop bad connections - especially the earth circuit - so ensure that is checked first.

I sincerely XXXXX XXXXX above all helps you and helps with the understanding of the problem you have -and what needs to be done to cure this ...
