Cruise Inhibited

Cruise Control Vehicle Distance Sensor Module Inhibits 

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

• The SERVICE ACC message is active in the driver information center.
• Initial brake pedal travel signal from brake pedal position sensor is not present
• An ACC System malfunction and/or failure is present.
• The FRONT RADAR BLOCKED CLEAN FRONT of VEHICLE indicator is active in the driver information center.
• An invalid vehicle speed
• The Antilock Brake System (ABS) is active during automatic braking.
• The Cruise Switch failed message from the BCM is sent to the cruise control vehicle distance sensor module.
• Automatic braking failure - A GMLAN signal from the electronic brake control module (EBCM) the to cruise control vehicle distance sensor module indicating an automatic braking failure
• The brakes overheated signal from ABS
• The cruise control vehicle distance sensor module transceiver temperature is hot.
• 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 cruise control vehicle distance sensor module is present.
• The vehicle speed is less than 45 km/h (28 MPH).
• The vehicle speed is greater than 190 km/h (118 MPH).
• Automatic braking failure - A GMLAN signal from EBCM to the ECM indicating an automatic braking failure
• The ACC present signal from the BCM 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 System failure is present.
• The Traction Control System 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 brake pedal position sensor is not present.
• The system voltage is too low.
