TuningBot DTC Database · v4.37.14
11 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
BMWThe control module detected a condition consistent with a leak affecting the Leakage Diagnostic Pump Control. This is the manufacturer-specific definition used by BMW.
HyundaiThe control module detected a fault associated with the Slow Duty Solenoid circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.
JaguarThe control module detected a fault associated with the Fuel Pump Relay circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jaguar.
Land RoverThe control module detected an interruption (open circuit) in the Fuel pump (FP) relay circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Land Rover.
MINIThe control module detected a fault associated with the Fuel Pump Relay Activation 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.
OpelThe control module detected that the Engine control relay voltage stayed below the expected range. This is the manufacturer-specific definition used by Opel.
PorscheThe control module detected a fault associated with the Fuel Injector Cylinder 6 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.
SubaruThe control module detected improper operation of the Fuel pump (FP) control module circuit. This is the manufacturer-specific definition used by Subaru.
VAGThe control module detected a short circuit to ground in the Injector 6 circuit. This is the manufacturer-specific definition used by Audi.
The control module detected a short circuit to ground in the Injector 6 circuit. This is the manufacturer-specific definition used by Volkswagen.
VolvoThe control module detected that the Mass air flow (MAF) signal stayed below the expected range. This is the manufacturer-specific definition used by Volvo.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (11 interpretations). The control module detected a condition consistent with a leak affecting the Leakage Diagnostic Pump Control. This is the manufacturer-specific definition used by BMW.
P1230 is a manufacturer-specific code. In this database it is documented for: BMW, Hyundai, Jaguar, Land Rover, MINI, Opel, Porsche, Subaru, VAG, Volvo. 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.
