Display on Tekonsha Primus IQ Brake Controller # TK90160 Indicates .c.

Question:

We have a Primus IC Tekonsha installed in our 05 Mercury Mariner to pull a pop up camper. We went camping last weekend without incident. I got in the veh a few moments ago and noticed on the unit in the veh had a flashing .c. Can you please help me with this???

There is nothing wrong with your Tekonsha Primus IQ brake controller.

The display .c. indicates that your controller is receiving power, that your trailer is connected, and that the controller's boost feature is engaged.

Please refer to the linked installation/operation instructions for the Primus IQ # TK90160. These explain the various display messages that can appear on your controller.
