Why Does Prodigy P2 Electric Brake Controller Not Turn Off

Published 10/08/2014

Question:

I have the p2 as shown in your video and the wire connector for factory plug under the dash. The issue that the prodigy has power with out the key being on and is lighting the display regardless if the key is in the tundra so disconnected it from the plug. What is happening for it to light the display with power off at the key?

Tekonsha Prodigy P2 trailer brake controller, # 90885, connects to a fused power source directly to the battery and not an ignition source. This means the controller draws power even with the key off. However, it goes into a kind of sleep mode after about 15 minutes of inactivity and will not draw much power from the vehicle battery.

If you will be parking the vehicle for an extended period of time, you can also unplug the connector at the back of the unit, which will immediately power down the controller.
