My ScanGauge by AreoForce is not working after I replaced my GPR.

I disconnected both ground to the batteries, replaced the GPR, tested the GPR with a multi-meter and all tested good.

I start my truck and now the ScanGauge will start up and only show the FORD POWERSTROKE and the AREOFORCE screens then it will shut off. over and over again.

I triple check the power supply to the gauge and all looks to be good.

Any ideal what would cause my gauge to stop working ?

 

Might try setting it back to stock if you have a tune installed. Then try it.
