Last night I was driving and trying to figure out the volume control to switch between MAPs for JB4 and the CEL came on.
I have the OBDII connector; is there a way to connect it to figure out what the code is?
I connected the laptop to JB4 and it was not giving me any codes.
I have recently installed the ER Catless DP, but I was under the impression JB4 squelched that code; also, I have the E-Series JB4 but Ando at BMS ensured me the new hex would make it a F-Series JB4 and it wouldn't work at all otherwise.
