Q: What does code U02A6 mean?

Lost Communication With Safety Integration Control Module. U02A6 is a generic network communication code indicating that one or more control modules have lost contact with the Safety Integration Control Module (SICM), a dedicated module that coordinates and monitors safety-related functions such as airbag deployment, seatbelt pretensioners, and crash sensors. The computer detected that expected controller area network (CAN) messages from the SICM stopped arriving within the required time window, so it flagged the module as missing from the network.
