Hello, I recently bought an Aeroforce Interceptor scan gauge from zzperformance.com. I have an 04 Grand Prix GTP and therefore ordered the PT version (PT 401 V2.8).
In scan mode, screen turns black after 2-3 seconds. When I touch the buttons, lights blink red. So basically it's not a power issue.
I searched on forums but haven't found my answer. It is plugged to the OBDII only and the jumper is still on. I haven't used the optional 3 wire harness. I also selected limited parameters, (RPM and MPG), in case some were not compatible, and still shuts down when putting it in scan mode.
I would really appreciate some help with this issue.
Thanks for your time.
