trouble with my 2002 corvette
I was getting reduced engine power warning and service traction control warnings last week. When i would reset problem it would go away. Then last weekend while driving I got reduced engine power, service traction control warnings but also temp gauge and oil pressure gauge were not working as well as the drivers side control module. Bought new red top battery and installed and problems went away for the day, but on Sunday got reduced engine power warning again. Took to local Chevy dealer and they could find nothing wrong so they said they reprogrammed the computer. Drove it today and lost driver side control module again, got reduced engine power warning and service traction control. Got the codes off of corvette and these were current
99-hvac u1160
ao-ldcm no comm
40-bcm u1255
40-bcm u1016
40-bcm 1096
Anyone got any ideas whats wrong.
PS The person I bought my car from,bought car from dealer August of 2003, and car has 14000 miles on it.GM said it is out of warranty because dealer put it in warranty when they took delivery in April of 2002. Is this bs or what?

RE: Codes
Pull the battery and the battery mount and the right fenderwell rear cover and the right front wheel. Look in there with a strong flashlight for battery acid damage to the TAC module, the vacuum lines and cannister, and the BCM in the right footwell inside the car next to the fuse box. It sounds as if there has been previous damage, hence all the codes it is throwing. The BCM will give you the body codes and the TAC will cause the power reduction. In addition, the "gas" pedal will cause power reduction if it is not putting out the proper voltage to the TAC module. The battery acid screws up everything. The dealer obviously doesn't know where to start looking. You can ask me how I've learned all this stuff in such a short time.LOL!

A 2002 model that was put in service in April 2002 makes plenty of sense. Sounds like you are owner #3 and the origional warranty would have expired in April 2005

I had the exact same problem as you did and it turned out my BCM had gone bad and it was replaced under warranty. That solved the problem for me. Coincidentally, mine is also an 02. It happened after I went to the memorial day Pocono track day so maybe the added heat and G-forces might have finished it off. They also replaced a ground wire as well which they said was starting to show corrosion. Don't know if that led to the problem with the BCM but you might want to have that checked out as well.

Just got home from work and will look into these things. I told the chevy dealership about the acid problem that people were having but the didnt look into. Also let me clear up the warranty issue. I didnt explain myself very well. Car was bought by person in August of 2003. This person was the first owner. Dealership drove the car, as a demo, from April of 2002 till they sold it in August of 2003. It had problem with seatbelt retractor so they warranted it in April of 2002. Thus starting the warranty. I always thought that warranty did not start till a person bought but chevy is telling me it can start whenever dealership decides to start it.

If the first purchase on your car was in-fact Aug 2003, I would definitely be on the phone to GM because what the dealer is saying doesn't sound right or fair.
Good luck! Hope this gets resolved in your favor.

THis car could easily have 12k on the clock at this point (8/03). You think GM is going to say, OK, you can start the warranty now, no problem.....

One other thought here, the AGM's are known to do flukey things when they die. Might be as simple as a bad battery, especially if all the problems came on at once. Swap batteries with a known good one and see if the problems clear up.
