The control module detected that the signal in the Fuel Level Sensor 2 circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Chrysler.

The control module detected that the signal in the A/C Refrigerant Temperature circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Ford.

The control module detected a fault associated with the Hybrid battery pack - deterioration circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.

The control module detected the fault condition "Additive pump fault" for the Particle filter additive system. Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected the fault condition "Additive pump electrical fault" for the Multiplexed additive pump. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected an interruption (open circuit) in the Secondary air injection (AIR) pump relay circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.

The control module detected an interruption (open circuit) in the Secondary Air Pump Relay (J299) circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17841. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
