U02A6Lost Communication With Safety Integration Control Module
- Generic OBD-II code · Network
- How the car detects it
- The Safety Integration Control Module is a name from the SAE code catalogue for which no carmaker publishes a role or a fitted model; the term points to a unit that bundles several safety functions, for instance restraint, braking and driver assistance data. U02A6 means another controller expects its cyclic messages and they no longer come. For safety signals that check is normally formalised: the AUTOSAR end-to-end protocol has the receiver watch the arrival of fresh data and declare a timeout once too many cycles pass without a valid new frame, alongside CRC and counter checks. ISO 26262 then requires a safe state for such faults. No manufacturer documents U02A6 or its partner U05A7 publicly. Typical results are warnings and switched-off assistance features, without an emissions link.
