TuningBot DTC Database · v4.37.14
10 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
BMWThe control module detected improper operation of the Battery temperature circuit. This is the manufacturer-specific definition used by BMW.
Battery temperature sensor
FordThe control module detected that the signal in the Fuel Pump Monitor circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Ford.
HondaThe control module detected that the Battery signal signal stayed below the expected range. This is the manufacturer-specific definition used by Honda.
JaguarThe control module detected improper operation of the CAN circuit. This is the manufacturer-specific definition used by Jaguar.
KiaThe control module detected that the Engine control module (ECM) - non immobilizer/ state or value did not match what was expected. This is the manufacturer-specific definition used by Kia.
ECM
Land RoverThe control module detected that the Fuel pump (FP) voltage stayed above the expected range. This is the manufacturer-specific definition used by Land Rover.
Mercedes-BenzThe control module detected a fault associated with the Engine control module (ECM) - incorrectly coded circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mercedes-Benz.
ECM coded for MT with AT fitted
PSAThe control module detected an interruption (open circuit) in the "MIL" warning lamp (Malfunction Indicator Lamp) (Application connected by wire only) circuit. 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.
RenaultThe control module detected a fault associated with the Heater relay control circuit 2 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Renault. Renault diagnostic tools (CLIP) report this fault as DF033.
VAGThe control module detected improper operation of the SRS control module - system. This is the manufacturer-specific definition used by Audi.
