Unfortunately, no..What I’ve tended to see referred to in the Isuzu Workshop Manual, is a Tech 2 scanner again they are in the region of £260.
Do you have any ideas on a cheaper way of getting a scanner or program for that vehicle?
Same requirement for Suzuki & they are not cheap (but cheaper than letting the dealer change multiple random parts to find a fault).
You could try mine, if you are reasonably near?
