U0461Invalid Data Received From Audible Alert Control Module
- Generic OBD-II code · Network
- How the car detects it
- The audible alert control module produces warning chimes, for an unfastened belt, an open door or lights left on; in GM's list of U codes for the 2011 Saab 9-5 the matching node is called chime alarm control module. U0461 is stored when a partner, often the body controller or instrument cluster that requests or confirms the tones, receives status frames from this module that fail plausibility; U0160 is complete silence. No manufacturer documents U0461 publicly. The function has a legal side: FMVSS 208 requires an audible belt reminder lasting between 4 and 8 seconds, so a disturbed chime unit can mean warnings that never sound or keep sounding. Because many current cars generate these tones in the cluster or radio, only some models have a dedicated unit. U0440 concerns the outside pedestrian sound, a different device. No MIL.
