grande traction control problem

[Zeb Walsh]

Hi, had 2004 Grande sitting for about a month, was driven daily and was fine. Now, driving along, the traction light comes on randomly, car loses power(because it thinks its losing traction) and brake pedal goes very hard?? this throws no lights or codes, so very hard to diagnose. Ay advice would be great

I would start by having a look at the wheel speed sensors and ensuring they have a clean, unbroken connection.
