Question:

It flashes error on the brake controller itself not on the dashboard cluster

It sounds like you installed the Draw-Tite Activator Trailer Brake Controller 5100 in a vehicle with an integrated factory brake controller. If that is the case, installing an aftermarket brake controller like the Activator will cause the instrument cluster to flash the error code you mentioned. While this can be annoying to look at, it does not interfere with proper functioning of the aftermarket brake controller.

The only way to clear the code is to take the vehicle to your local dealer and have them disable the TBC (trailer brake control) through the settings in your IDS (internal diagnostics system). In the event the aftermarket brake controller is removed, the same process can be followed to re-activate the TBC on your vehicle.

The DrawTite Activator 5100 referenced in your question doesn't have an LCD display as it only uses an LED indicator light. If you have a DrawTite Activator with an LED display, you probably have the # 5504. Assuming that is the case, the "Er" code indicates an internal short and the brake controller will need to be replaced. I have attached the user manual as well as a snip of the troubleshooting chart for you to reference. A great replacement/upgrade at a similar price point is the Brake Controller # TK63VR. This is a proportional brake controller which aromatically applies the trailer brakes based on the deceleration of your tow vehicle. Because of this, proportional brake controllers help prevent wear on both your trailer's and tow vehicle's brakes. Another great thing is that it will plug right in to the same connection previously used for the old brake controller.
