2017-2022Chevrolet Bolt EV

P1FFF is an OBD-II diagnostic trouble code meaning “Manufacturer-Specific Code (hybrid/EV system, unconfirmed).” P1FFF is a manufacturer-specific alphanumeric code with no single standardized definition; some sources associate it with a hybrid/EV battery charging or system isolation/coolant-level condition, but this varies by manufacturer and is not reliably confirmed. As an alphanumeric P1xxx code it is defined by the individual carmaker, so the exact meaning depends on the specific vehicle. In general it indicates the powertrain or high-voltage system control logic flagged an abnormal condition. Confirm the precise definition with manufacturer-specific service data or a capable scan tool before diagnosis. This code is most commonly reported on 2017-2022 Chevrolet Bolt EV.
