Everything was working fine and I had the key on and I went to plug in a Evo scan cable and right as I plugged in the cable the alarm started going off. I've tried multiple things and it will not go off. Does anyone know how to disable the alarm system permanently. ? Thanks

 

The USDM Evo 8 doesn't have an alarm.

 

Problem solved. Pin 9 on the Evo scan 1.3 cable shorter the etacs box so the horn lights and wiper went on making it seem like it was an alarm.

 

great thank you
