U0495Invalid Data Received From Digital Audio Control Module B
- Generic OBD-II code · Network
- How the car detects it
- U0495 is the invalid-data code for a second digital audio unit, module B. Where slot A is used at all, it tends to be the digital or satellite radio receiver, as in GM's Saab lists; for B no public code list or bulletin names a concrete device, and no maker documents U0495. The partner U0194 does appear in GM bulletin 15-NA-004 (2013-2016 Acadia), but only as one of eleven lost-contact codes traced to a low-speed LAN lead crushed by the rear climate duct in the headliner, which reveals nothing about module B itself. A stored U0495 should therefore first be checked against the vehicle's own module list, then software levels and the bus link. At worst one digital audio source is missing; no MIL.
