Circuit Description
WARNING: This page is about a different car, the 2004 Saturn Ion Red Line, 2004 Saturn Ion 3, 2004 Saturn Ion 2, and 2004 Saturn Ion 1. However, it is still accessible from the selected car via links, so may be relevant.
To control which direction the cruise control module moves the accelerator pedal, the engine control module (ECM) commands the Cruise Control Servo Move Direction Signal circuit either high, wide open throttle (WOT) or low, idle. If the Cruise Servo Move Direction Signal circuit is commanded high and the ECM detects low feedback voltage, DTC P1582 will set.
