abs/brake light/hill descent warning lights going off

[rvtrcr]

I'm having the same issue - BUT - my truck starts acting like it's misfiring and will die repeatedly... especially if it's wet out. I know it has at least one bad front wheel speed sensor. But I'm wondering why it is misfiring and stalling.. haven't seen that issue in anything I've read here. An suggestions? Thanks.

my pcm was replaced in the engine bay. if it got wet my truck would run like crap. the seals on the plugs went bad so any puddle or water that got onto the pcm shorted out the system and made my truck run terrible. try using a littlw water and see what happens when the pcm gets wet

Interesting - I pulled the codes - I'm getting a code for mass air, and U0401 , which is "invalid data from ECM/PCM" I'll go out and pull the plugs and see what I find. Thanks.

Pulled the plugs - no water.

try keeping everything plugged in and use a hose to water it down. it should be water tight. this and the 3rd brake light are the only things i have seen cause this
