His last post ever was the one in this thread...it sounds like he gave up.
Because no one has answered you yet, I'll tell you what I would do in your position, but I don't know much, and someone who knows more might still help.
You need a device with forscan software with an extended licence and a working OBD adapter (am pretty sure all that is detailed earlier here if you need that).
I prefer a windows laptop and a USB OBD adapter. Less potential issues.
Then you need 2 working keys and hopefully they are originals.
If one or both are clones, they may still work, depending on the type of clone (again there is info earlier in this thread on how to work around 1 working key with foil).
Then I would follow the prompts in forscan to do the key reset.
If your
ECU and
BEM are ok, this should resolve your problem.
As I understand it the
ECU/
BEM can just lose it's programming and this will fix that (although I have not had this problem - but I have swapped
ECU's before - which causes the same effect - and this process does work).
If the process completes but your problem still exists, then it is likely to be a faulty
ECU or
BEM.
If you've just got a standard 6 cyl ute then you can probably pick up both from a wreck for $50.
If you have an XR/V8 then you might have to search harder for the
ECU. Ebay is usually good still. But I believe it must be a ute
ecu.
I think all S2 & S3
BEM's are pink and the the same? If they don't come as a pair.
