7 manufacturer-specific interpretations across 6 manufacturers in the TuningBot DTC database.
FordThe control module detected a fault associated with the Alternator Load Input Failed circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
HondaThe control module detected improper operation of the Accelerator Pedal Position Sensor 1 circuit. This is the manufacturer-specific definition used by Honda.
Land RoverThe control module detected improper operation of the Alternator, load input circuit. This is the manufacturer-specific definition used by Land Rover.
MazdaThe control module detected that the Generator/regulator system - load input value was outside the valid range. This is the manufacturer-specific definition used by Mazda.
MitsubishiThe control module registered the fault condition described as "Engine control module (ECM) - processor fault". This is the manufacturer-specific definition used by Mitsubishi.
ECM
VAGThe control module judged the Injector needle lift behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Audi.
The control module judged the Needle Lift Sensor (G80) signal implausible when compared with other operating data. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17654. 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 (7 interpretations). The control module detected a fault associated with the Alternator Load Input Failed circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.
P1246 is a manufacturer-specific code. In this database it is documented for: Ford, Honda, Land Rover, Mazda, Mitsubishi, 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. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
