U0151 on Chevrolet
Lost Communication With Restraints Control Module
U0151 on Chevrolet vehicles indicates lost communication with restraints control module. Au7o has documented this code across 1 Chevrolet model — most commonly on Bolt EV. 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.
Common Causes of U0151
- •Loss of power or ground to the restraints control module
- •Blown fuse feeding the module
- •Wiring or connector fault on the bus circuit
- •Corrosion at module connectors (often under-seat moisture)
- •Faulty restraints control module
- •Bus communication wiring damage
U0151 on Chevrolet by Model
Chevrolet Bolt EV(1 issue)
- Infotainment Screen Ghosting and Flickering2017-2023
The 10.2-inch infotainment touchscreen in the Bolt EV develops ghost touch inputs, screen flickering, unresponsive areas, and random screen blackouts. The screen registers phantom touches that change radio stations, adjust climate controls, or activate features without driver input. The issue is caused by a failing digitizer layer in the touchscreen or a loose ribbon cable connection behind the display. Hot weather and direct sunlight on the screen exacerbate the ghosting behavior. The issue affects both the original infotainment system and the updated system in 2020+ models.
