Lack of active braking
  • CCM
  • Front bumper cover
The CCM may not detect and respond to vehicles or moving objects, such as bicycles, performing close cut-ins or on tight curves (especially on the passenger side) due to limited CCM field of view. CHECK the CCM, CCM mounting bracket and front bumper for damage. REFER to: Cruise Control . If no damage is observed, RETEST the system.
