The good news is that ive solved the gateway issue it seems after cleaning and re wiring some ugly grounds. No more CEL after startup after I cleared the codes. In the past the GP code errors would return on the first key cycle. I do still have the issue of the red light non communication though. The frequency of this issue is greatly increasing though.
Always worth removing the connector on the Gateway Module and cleaning the Male and Female sections extremely well. The location of the Gateway Module in the engine bay makes it prone to getting covered in water, mud snow and salt etc.
I have seen a video on jeepkj.com I think which shows that if you disconnect the Gateway Module connector and start the Jeep...the Red light comes on solid and Jeep runs badly!
