traction control light came on truck in limp home mode
Ground hog day, I'm sick, and the temperatures just dropped from above freezing to -25, I started the truck a 2010 Colorado extended cab with the 2.9 and auto transmission, got over to the kid's place and as I was leaving bing bing bing traction control light CEL and it will only rev to 1500 and top speed is 30kpm. Oh and there is a fire downtown so Im in a lineup to try and get into a lane to get back home.
Took the other kid's car to drive the one to school and got back 45 minutes later and now the truck runs find. That Passkey light came on a few days ago when it was warm but when I restarted it the light went out. I have one of those ELM 327 bluetooth OBD readers which I plugged in and got 4 pending fault codes B2AAA, P0449, P0455 and P2135. About 3 weeks ago it was in the +5 temperature and I washed the truck and a day or 2 later we dropped back to the -20s and that was the first time this happened. Then I figured it was the OBD reader because I had left it plugged in and I thought it might be condensation inside the ELM327, because once I pulled it out the truck ran fine.
We had a 2006 Torrent that did the same thing and the cure for it was to pull the plugs out of the body control module, clean them with contact cleaner and seal them up with dielectric grease. Does the Colorado have and problems with the BCM and poor contacts?
