Customer Question

I have a 2007 Buick lacrosse. Recently I had an electronics issue which I'm still fighting with. I finally got the car to start running and it seems to drive fine. however my gauges seem to be running in reverse and my traction control light is on. I hooked up my obd2 reader and I show no codes. I don't want to go blindly hacking away at my system, any ideas would be appreciated.

Disconnect battery and touch cables together with battery disconnected for 2 minutes, this will reset system. Let me know if it helps, thanks.

Sorry to bother you again. I tried doing as you suggested. All the car does now is shut off the gauges and honk the horn till I let off the starter.

I got it figured out. I still have the traction control light on but I got everything else figured out. I still haven't heard from the gentleman you referred me to. What it turned out to be was a Com link issue caused by condensate in the ecm module. I disassembled the unit dried it out with a hair dryer and now it works perfect. We've had freezing rain storms here lately and sub-zero temperatures.
