Circuit Description
WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
The powertrain control module (PCM) has the ability to inhibit cruise control operation if conditions exist that would make cruise operation undesirable. The PCM removes the ground from the cruise control inhibit circuit in order to disengage cruise control operation. The following conditions may inhibit cruise control operation:
- The engine speed is too high or too low.
- The vehicle speed is too high or too low.
- The traction control has been active for longer than 1 second.
- The vehicle acceleration or deceleration rate is too high.
