Sensors Going Haywire

peteking · April 24, 2009

OK this is probably something simple but I'd like to double check. I installed a new PCM because my truck is going to be tuned by Justin next weekend. Started by disconnecting my battery, remove old PCM according to instructions, install new computer without trouble. The truck even fired right up (sweet! No security relearn needed...) So then I take the truck around a few blocks near my place. She runs just fine, but then after 5 minutes of driving around....by DIC goes haywire and tells me to service my brake system. The ABS warning light is on solid too. I pull over and shut down. After 2 minutes I fire up the truck again and drive back to my place. Same thing happens. After a few minutes my DIC screams at me to service my brake system. I decide to humor my truck by crawling under to check for leaks and also check the fluid level. Everything seemed fine just as before.

I just want the damn beeping to go away. What am I missing?

I wonder if the new computer and old computer have the same settings for the Tire size and Gears? This could be throwing the Brake Anti Lock timming off.

Did you call/e-mail/PM Justin or Jenna about it? I assume you got the PCM from them, right?

Yeah that's my next step. I'm sure it's something Justin could fix with his laptop. But the warning sure scared the heck out of me when I first heard it!
