Circuit Description

WARNING: This page is about a different car, the 2004 Chevrolet Monte Carlo and 2004 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.

The PCM has the ability to inhibit cruise control if conditions are detected which would make cruise control operation undesirable.

The PCM will interrupt the ground on the cruise inhibit circuit to request that cruise control be disengaged.
