U0279Lost Communication With Haptic Control Module
- Generic OBD-II code · Network
- How the car detects it
- A haptic control module produces vibrations or pulses that the occupants feel, for example in the steering wheel, a seat or the floor. Where it sits varies: the 2026 Range Rover has separate haptic floor modules under the carpet, while on the 2019–2022 Hyundai Palisade the haptic steering wheel motor is driven by the integrated central control unit, so there is no separate network node. Care is needed with Maserati, whose HALF (haptic lane feedback) unit is really the forward-looking camera. U0279 means the module expected for this function has gone silent on the bus. No manufacturer publishes the code. Driving is unaffected; only tactile warnings or comfort effects stop, while visual and audible warnings remain.
