U0151: Lost Communication with Restraints Control Module (SRS)
Can you still drive? Driving is strongly discouraged. All airbags and seatbelt pretensioners are disabled — no crash protection is available for any occupant. If you must drive, go directly to a repair facility and avoid highways.
What Does U0151 Mean?
Code U0151 indicates that the vehicle's CAN bus has lost communication with the Supplemental Restraint System (SRS) control module, also known as the airbag control module. This module manages all airbag deployments, seatbelt pretensioners, and crash sensors. Without communication, the entire airbag system is disabled.
