Gen 1, hill descent control fault, service advance trac, check brake system

Really surprised your 3rd brake light wasn't the culprit - are you able to swap the unit out with another one (got a spare or maybe even junkyard or aftermarket?). All those symptoms were definitely screaming "3rd brake light," the price of a new OEM 3rd brake light skyrocketed several years ago, wonder if they're even still available...

My 2011 Screw's light was badly faded as my Gen1 was a work truck and spent most of it's time outside. I also have the rusted cab corners and the stains on the headliner due to the seal failing. I replaced it with this Morimoto B-ASY-X3B20-MM option.


Looks pretty good on my Tuxedo black Gen1...



The gasket is very thick too and should keep it's seal for a long time, although she's a garage queen and won't see too much sun except when I drag my jetski to the lake or haul my RC aircraft to the flying field.

I ponied up the extra $25 for the flasher module. works great. Not sure what a new OEM replacement is now, but for $225 I feel it's a better option.
Good luck with your repair.

I have the same one, also with the flasher module. Very happy with it and it looks GREAT.

Brake pressure is reading a steady 23,000 kpa with or without the brake pedal being actuated. I disconnected, cleaned and reconnected front speed sensors, cleared codes, all four wheels read speed now with no new wheel speed sensor codes. I think most everything is coming from the C116A-E0 ABS Pressure Transducer/Brake Switch Mismatch. It looks like the pressure sensor in the abs module lost its mind. So either the hydraulic pressure module or the electrical module that’s mated to it.
