JB4 Installation Help (Solved)
I'm installing the JB4 right now and it it is giving me hard time.
First I switched two connectors and the car didn't start, I realized the mistake I had made and corrected it.
Now everything is way it is supposed to be and the engine starts but it is not running as it suppose to. It has vibration and Service Engine Soon is ON.
I tried to go into JB4 menu to read the error codes, but when I press the Channel + Volume down bottoms at the same time, no menu comes up, only a yellow screen.
This makes me think that the JB4 is not ON or has no power. I doble checked the connection to the JB4 unit and everything seems the way it shows in the manual.
Any help will be appreciated.
Note: I also installed angel eyes and CAI at the same time.
