- How the car detects it
- P2BAF does not name a faulty part; it states that the driver inducement of the NOx control system has been activated. Regulation (EU) 2017/1151 Annex XVI requires such an inducement once reagent is lacking, of wrong quality, under-consumed or not dosed, typically counting down to a blocked engine restart; the reason and the distance driven with it go into non-erasable records kept for 30,000 km or 800 days. FCA bulletin 08-103-19 lists P2BAF-00 as Driver Inducement Active on the 2020 Jeep Compass 2.0 diesel, there caused by body control module software. Jaguar Land Rover lists P2BAF with P2BAE as DEF inducement codes next to root codes like P2BA9 or P208B. Repair the root code first; P2BAF then clears. P241D, by contrast, signals a forced shutdown.
