Circuit Description

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The PCM has the ability to inhibit cruise control operation, if conditions exist that would make cruise control operation undesirable. The PCM will interrupt the ground on the cruise inhibit circuit to request that the cruise control be disengaged. The PCM also monitors the voltage on this circuit in order to determine if a fault exists.
