Distance Sensing Cruise Control (DSCC) Module

WARNING: This page is about a different car, the 2007 Cadillac XLR. However, it is still accessible from the selected car via links, so may be relevant.

The adaptive cruise module (ACM) disengages cruise control for various reasons. The ACM disengage reasons are available in the scan tool for display when the ACM disengages cruise control. When a cruise control disengagement occurs, be sure to view both the DSCC data and engine control module (ECM) cruise disengagement data.

These Scan Tool Data Definitions contain a brief description of the cruise control disengage parameters available on the scan tool for display. One of the following conditions must be present in order for a disengagement parameter to be displayed:

The cruise control system is active and disengagement is requested.
The engagement of the cruise control system is requested while a fault is present.

ABS Active: The scan tool displays Yes/No. The ACM disengages adaptive cruise control (ACC) function when the ABS is active.
ABS Malfunction: The scan tool displays Yes/No. The ACM detects that the ABS system is malfunctioning.
ACC Ready: The scan tool displays Yes/No. The ACM detects that ACC may be inhibited and not ready to be activated.
ACC Configuration: The scan tool displays Yes/No. The ACM detects the an error exists in the ACC configuration.
ACC Amp. Not Ready: The scan tool displays Yes/No. The ACM detects that the audio amplifier is not active or is malfunctioning.
Brake Pedal Pressure Detected: The scan tool displays Yes/No. The ACM detects that the brake pedal is being applied.
Brake Pedal Travel Detected: The scan tool displays Yes/No. The ACM detects the brake pedal travel.
Brakes Overheated: The scan tool displays Yes/No. The ACM detects that the vehicle brake system is overheating.
Cruise Control Malfunction: The scan tool displays Yes/No. The ACM detects that a malfunction exists in the DSCC module.
Cruise Control Switch Malfunction: The scan tool displays Yes/No. The ACM detects that a cruise control switch malfunction exists in the ACC system.
Cruise Control Switch Off: The scan tool displays Yes/No. The ACM detects that the cruise control switch is off.
ECM Cruise Disengage: The scan tool displays Yes/No. The ACM detects that the cruise control system is disengaged by the ECM.
HUD Malfunction: The scan tool displays Yes/No. The ACM detects that the head-up display (HUD) is not available or is malfunctioning.
Internal DSCC Overtemp: The scan tool displays Yes/No. The ACM internal overtemperature occurs.
Invalid Vehicle Speed: The scan tool displays Yes/No. The ACM detects that the vehicle speed is invalid.
Not in Run Mode: The scan tool displays Yes/No. The ACM detects that the vehicle is not in run mode.
Radar Needs Cleaning: The scan tool displays Yes/No. The ACM detects a forward looking sensor (FLS) radar blockage or malfunction.
Supply Voltage Out of Range: The scan tool displays Yes/No. The ACM detects that the supply voltage is out of range.
Yaw Rate Invalid: The scan tool displays Yes/No. The ACM detects that the yaw rate is invalid.
