Troubleshooting P.L. Error Code from Prodigy P2 90885 in 2014 Ram

Question:

I had collision work on my 2014 Dodge Ram and when I received my truck back the PL code comes on my prodigy p2 break control when towing my travel trailer. It has power but feels as if the brakes are not engaging. All the collision work was on the front of my truck and under the hood.

The P.L. error code appearing on your Tekonsha Prodigy P2 # 90885 indicates that the power connection is being interrupted while your foot is on the brake pedal. This means that you will want to focus on both the controller BLACK power wire and WHITE ground wire connections.

The issue could be as simple as a bent contact on the installation harness # 3023-P which is the part used to install the P2 in your truck. It is also possible that corrosion on either of those +12V and ground contacts is interrupting the power to the controller. In this case a spray-on electrical contact cleaner like Caig De-Oxit may do the trick.
