Thanks for the reply
im sat in it now! Ok the led is flashing every 3 seconds , if I turn the ignition on the clocks fire up, fuel gauge reads, everything does what it should. The 2 lights stay on and the led just flashes as it was before every 3 seconds. I've tried waiting a minute to see if it gives and codes but nothing?
The battery is brand new. Everything in the cab works, ac , fan, lights etc. I've checked fuses in both boxes, and also swapped the relays around just in case. Still nothing?
Im wondering if the transponder isn't working? Both keys do the same thing?
