  1. Align the FLS radar. Refer to Distance Sensing Cruise Control Aiming .
    • If alignment cannot be achieved within the limits of the available adjustment, inspect the mounting structures and brackets for damage or tampering and repair as necessary to achieve proper alignment.
  2. Road test the vehicle and ensure the ACC system functions normally and DTC C1002 does not set as current. Refer to Cruise Control Description and Operation (Conventional Cruise Control)  or Cruise Control Description and Operation (Adaptive Cruise Control) .
    • If DTC C1002 resets as current, replace the FLS radar.
