MM3 Flashing - no screen

[JAFO]

My MM3 screen is not displaying, and the LED on the right is flashing (red red green red red).

I’m on the road, and would like to get this remedied if possible.

Any affect on performance?

Am I going to go into limp mode?

Its just the power cord in the back is not fully seated for powering the monitor.

Wiggle the cord/mess with the connection until the monitor resumes.

No worries on limp mode or anything you don’t actually need the monitor as the tune is already flashed into the ECM.

Still no joy.

I had that happen to me.

I just unplugged the OBD plug and then plugged it back in with some more squeeze and it worked fine.

Just check all your connections. Probably just a loose wire.

Cycling the OBD port worked.

I have had this happen a few times, a lot of vibration to make It come loose and as you know it does stick out and can get wacked with a leg. So for now I have tiny zip ties to help. I need to look deeper In this because I read on another forum that the obd can be moved and flipped backwards. this may help with it sticking out. I will post up when this happens.
