K123761X004 | Genuine Bendix Front Radar Sensor FLR-21, Wingman Advanced

Description: The Front Radar Sensor FLR‑21 K123761X004, used in the Bendix Wingman Advanced (or Wingman Fusion) system, is a radar unit mounted at the front of a vehicle (typically a truck) that provides the sensing capability for advanced driver assistance features (ADAS). Part Number: K123761X004  Condition: New Manufacture/Brand: Bendix Specifications For K123761X004:  Application: Wingman Fusion 2  Product Type: FLR-21  CAN Baud Rate: AutoBaud  Connector: MCON Interconnection System 10-Way Sealed Connector (Female)  Software Version: BX193102  Maximum Operating Temperature: 185 °F (85 °C)  Minimum Operating Temperature: -40 °F (-40 °C)  Fits K123761X004 For Volvo, Mack, International, Freightliner, Kenworth, Peterbilt, Western Star Purpose of using K123761X004  Adaptive Cruise Control (ACC) with Braking: When cruise control is active, the system keeps a safe following distance from the vehicle ahead by adjusting throttle, retarder, or applying the foundation brakes if needed. Collision Mitigation / Autonomous Braking: If the radar detects a potential forward collision or rapid closing distance, the system can apply braking to reduce the severity of impact.  Alerting the Driver: Provides alerts (visual and/or audible) when a vehicle or object is detected ahead or if the following distance becomes unsafe.  Stationary Object Detection: Can warn the driver about stationary vehicles or objects in the driving path. Signs of a Bad Front Radar Sensor K123761X004  1. Warning Lights or System Alerts Dashboard alerts such as: “Wingman Advanced Fault” “Radar Sensor Fault” The system may disable itself until the sensor is repaired or replaced. 2. Adaptive Cruise Control Malfunctions ACC may fail to maintain distance from vehicles ahead. The system might fail to engage or disengage unexpectedly. 3. Collision Mitigation / Braking Issues Forward collision alerts or automatic braking may not work. Braking may activate unexpectedly if the radar misreads objects. 4. False or Erratic Alerts Radar may detect objects that aren’t there. System may constantly beep or show visual warnings without reason. 5. Inconsistent Detection of Vehicles or Obstacles Vehicles ahead may not trigger alerts. Stationary objects (parked cars, barriers) may be ignored. Performance may vary with speed or weather conditions. 6. Physical Damage or Obstruction Sensor lens cracked, chipped, or covered in dirt, snow, or ice. Mounting misaligned after a collision or maintenance. 7. System Self-Test Failures On startup, Wingman Advanced performs a self-diagnostic. If the FLR‑21 fails, the system may refuse to operate or report an error.
