- Generic OBD-II code · Network
- How the car detects it
- U0196 refers to rear entertainment control module A, the unit that gives rear passengers their own audio or video source, headphone zones and screen control. GM's Saab U-code lists assign it to the rear audio control module for the 9-5 (2010-2011) and the 9-4X (2011), meaning the rear audio panel with headphone sockets. The front radio or the gateway logs U0196 when that panel's cyclic messages are no longer received at normal voltage, following GM's logic for U0100-U02FF. The NHTSA index lists no bulletin for this code. Rear buttons, headphone output or rear monitors stop working, while the front system usually plays on. U0191 is the TV tuner, U0184 the radio, U0497 invalid data from the rear unit. No MIL.
