Most Reported On
U0151 is an OBD-II diagnostic trouble code meaning “Lost Communication With Restraints Control Module.” This network (U) code means other modules have lost communication with the restraints control module (the airbag/SRS computer) over the data bus. Because the restraints control module manages airbag and seatbelt pretensioner deployment, a communication loss can mean these safety systems are unavailable and the airbag warning light is typically on. The cause is usually power, ground, wiring, or connector related, though the module itself can fail. This is safety-critical and should be diagnosed promptly. This code is most commonly reported on 2017-2023 Chevrolet Bolt EV, and 2022-2024 Jeep Grand Cherokee, with repair costs ranging from $150 to $1,400.
