- DTCs P1553 (Distance Sensing Cruise Control Signal Message Counter Incorrect) and/or P15F6 (Front Object Detection Control Module Torque Request Signal Message Counter Incorrect) may be set when the Adaptive Cruise Control subsystem components power up after some ignition cycles. These two DTCs will quickly transition to history. This is a known issue that has no impact to the operation of the Adaptive Cruise Control system.
- The Adaptive Cruise Control module should not be replaced based on these two codes being observed in history status.
