TuningBot DTC Database · v4.37.14
4 manufacturer-specific interpretations across 3 manufacturers in the TuningBot DTC database.
HondaThe control module detected a fault associated with the Generator system - high voltage 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.
MazdaThe control module detected improper operation of the Intake manifold air control solenoid - control circuit. This is the manufacturer-specific definition used by Mazda.
VAGThe control module detected an interruption (open circuit) in the Turbocharger (TC) wastegate regulating valve 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 Boost Pressure Controle Valve (N75) 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 17957. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (4 interpretations). The control module detected a fault associated with the Generator system - high voltage 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.
P1549 is a manufacturer-specific code. In this database it is documented for: Honda, Mazda, VAG. The same number can mean something different on other brands.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
