Wiring loom shorting bringing ABS and other systems down

Hello Neil,
Out of curiosity where was the wiring fault and how long did it take to find?
I only ask because I have an annoying habit of taking on these types of problems
And often ask myself why
Thanks
Ian

Hi Ian


Long story short

The fault initially was very intermittant then was bringing more systems down.
Armed with several pages of fault codes
we started to disconnected systems and started with ABS pump and almost immediatley saw a rub thru point on the loom 6" from the connector as it passed the pump unit.

More luck than judgement but I suppose Its knowing what area to initially check then its in the lap of the gods

Thanks for your reply
Ian
