There are a couple of reasons why your Primus IQ trailer brake controller # TK90160 could be flashing. It could be a bad ground connection, an overload or the angle of the controller not accurate for use. The angle is an issue because it utilizes an internal sensor to determine deceleration for the proportional braking of your trailer. I've attached a photo of the troubleshooting in the manual as well as the instructions to assist.

If this doesn't help solve your flashing, then give me some more info and a photo of the display and we can continue to troubleshoot.
