I was thinking it was the HPFP, I went to my local garage and they attached the error coding system but they couldn't find the error code. I tried driving it hard with the JB4 turned off to see if the light would appear, but it stayed off.
Really want a solution for this! Hate to have a JB4 that is not functional!
