Cruise Inhibited

DSCC Module Inhibits 

The distance sensing cruise control (DSCC) module inhibits the Adaptive Cruise Control (ACC) System when any of the following conditions exists:

• The RADAR NOT READY message is active in the driver information center (DIC).
• Initial brake pedal travel signal from brake pedal position (BPP) sensor is not present
• An ACC System malfunction and/or failure is present.
• The CLEAN RADAR indicator is active in the DIC.
• An invalid vehicle speed
• The Antilock Brake System (ABS) is active during automatic braking.
• The Cruise Switch failed message from the IPM is sent to the DSCC module.
• Automatic braking failure-a GMLAN signal from the electronic brake control module (EBCM) the to DSCC module indicating an automatic braking failure
• The brakes overheated signal from ABS
• The ACC System audible warning is not present, due to an audio amplifier failure.
• The DSCC module transceiver temperature is hot.
• The ACC is not present-the ACC can be disabled through the IPM ACC disable feature.
• The driver applied brake pressure.

ECM Inhibits 

The ECM inhibits the ACC System operation when any of the following conditions exists:

• The ACC inhibited signal from DSCC is present.
• The vehicle speed is less than 32.2 km/h (20 mph).
• The vehicle speed is greater than 193.1 km/h (120 mph).
• Automatic braking failure-a GMLAN signal from EBCM to the ECM indicating an automatic braking failure
• The ACC present signal from the IPM is false.
• The driver applied brake pressure.
• A cruise control switch failure is present.
• The park brake switch signal from the IPM is active.
• A Throttle Actuator Control (TAC) System failure is present.
• The Traction Control System (TCS) is active.
• The ABS is active.
• The engine speed protection is active.
• The vehicle speed protection is active.
• The engine speed is too high or too low.
• The automatic transmission is in first gear, Park, Neutral or Reverse.
• The initial brake pedal travel signal from the BPP sensor is not present.
• The system voltage is too low.
