Forward Collision Alert Inoperative, Unwanted Application of Emergency Brakes and/or Adaptive Cruise Control Drops Out
Condition
Some customers may comment on one or more of the following conditions:
• Forward Collision Alert (red light and alarm) is late or does not come occur.
• Vehicle applies emergency brakes with no vehicle in front in areas with overhead structures.
• Adaptive Cruise control drops out in barren landscape areas. Adaptive Cruise Control Temporarily
Unavailable message appears in the IP.
Cause
This condition may be due to one of the following:
• Software occasionally takes longer than normal to identify a potential collision situation.
• Radar reflections look like an actual vehicle causing a brief activation of brakes.
• Radar does not see enough reflections so it assumes it is blocked and goes offline.
Correction
An updated software calibration has been released to address these conditions. A learn procedure (“service alignment” or “service calibration”) is not required.
