8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
The control module detected that the VVT control motor, bank 1 - supply voltage stayed below the expected range. This is the manufacturer-specific definition used by BMW.
The control module detected that the Cruise Vehicle Speed/Set Speed Difference value was above the expected limit. This is the manufacturer-specific definition used by Chevrolet.
The control module detected that the Cruise Vehicle Speed Set Speed Difference value was above the expected limit. This is the manufacturer-specific definition used by Chrysler.
The control module detected that the signal in the Motor commutation sensor C circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Honda.
The control module detected a fault associated with the Cruise Control Switch Multifunction Steering Wheel circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
The control module detected that the System Voltage value was above the expected limit. This is the manufacturer-specific definition used by Suzuki.
The control module detected a fault associated with the Fuel quantity adjuster - lower stop value circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Audi.
The control module detected that the Quantity Adjuster (N146) value was below the expected limit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17971. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

Diagnostic Trouble Code (8 interpretations). The control module detected that the VVT control motor, bank 1 - supply voltage stayed below the expected range. This is the manufacturer-specific definition used by BMW.
P1563 is a manufacturer-specific code. In this database it is documented for: BMW, Chevrolet, Chrysler, Honda, MINI, Suzuki, 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.
