U0160Lost Communication With Audible Alert Control Module
- Generic OBD-II code · Network
- How the car detects it
- U0160 is stored when the audible alert module, the unit that produces chimes for an open door, unfastened belt, key left in or lights on, drops off the bus. GM uses it: the Saab 9-5 (2011) U-code list calls the unit Chime Alarm Control Module, and by GM's generic procedure the code appears once the chime unit's cyclic status frame stays away while the supply is within 9 to 16 V. Many newer vehicles let the instrument cluster or the radio play these tones, so a separate module exists only on some models. U0461 covers implausible data from this module; U013F concerns the external pedestrian sound generator, a different device. Warning tones fall silent or sound constantly; no MIL.
