P2696Injector Data Incompatible
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- How the car detects it
- P2696 is the collective version of P268C–P2695: the controller rejects stored injector correction data without naming a cylinder. That suits systems that check the data block as a whole, or engines with more than ten cylinders. No manufacturer documents P2696 publicly; GM and Ford use the per-cylinder codes instead. CARB allows a maker to flag only the minimum number of wrongly compensated injectors that raises emissions, which can make a shared code sensible. A real case of lost data is Mercedes-Benz campaign NCU-2023060006: on 2012 S-Class diesels the six injector codes could vanish during an emission software update, with a MIL and sometimes louder or rougher running.
