So back to the ute.
Well the thing wouldn't start which is why I got it cheap, I immediately suspected it was the "Smartlock" immobiliser working far too well!
So after doing diagnostics I came up with error 844, which is the smartlock........Yes!
I love it when my early hunches are correct.
So I then studied the wiring diagram and noticed there were several fused inputs to the "Body Control Module" which controls the smartlock function amongst others, one of which was for the interior light, which wasn't working.......pulled the lnterior light fuse, and found the contacts dirty, replaced it with a new one and............Success!
It started straight away first tun of the key and runs like silk.
I had a real F.I.G.J.A.M. moment (Fuck I'm Good, Just Ask Me)
I've now replaced all the fuses and fusible links as a matter of course, to ensure no further problems.
So it looks I've picked a winner. :
