trailer brake controller?

TBC = trailer brake controller. The gain adjustments the amount of braking force the trailer brakes have.
If you're towing something with electric over hydraulic brakes, then the onboard brake controller will not be able to energize the brakes and thus the light. However, I've noticed a few threads doing some searching that people get that error light with a faulty gauge cluster... |
