Circuit Description

The cruise control Resume switch is a normally open switch that closes when the switch is activated. When activated, the switch supplies signal voltage to the cruise control ON signal circuit. The powertrain interface module (PIM) converts the signal voltage input into serial data, which is used by the engine control module (ECM) to enable or disable the cruise control system, and by the instrument cluster to display cruise control status.

DTC Descriptor
