Circuit Description

WARNING: This page is about a different car, the 1995 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

PCM monitors activity of the normally-closed brake switch. Switch opens when brake pedal is applied. Code will set if PCM has seen conditions which would have required brake applications at least 7 times and no transition in brake switch has been detected.
