TuningBot DTC Database · v4.37.15
10 manufacturer-specific interpretations across 8 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the PCM Stack Overrun circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
FordThe control module detected a communication fault involving Inductive Signature Chip on the vehicle network. This is the manufacturer-specific definition used by Ford.
ECM
Ford documents P1636:00 (no sub type information) for its 2024-2025 gasoline-engine OBD monitor strategy as main micro loses communication with chip(s) that controls the solenoids. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.
HondaThe control module detected improper operation of the Motor power inverter module - internal circuit. This is the manufacturer-specific definition used by Honda.
HyundaiThe control module detected a fault associated with the Voltage Regulator For Injector 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.
MazdaThe control module detected a communication fault involving Engine control module (ECM) on the vehicle network. This is the manufacturer-specific definition used by Mazda.
ECM
SuzukiThe control module detected improper operation of the Immobilizer infonmation registration. This is the manufacturer-specific definition used by Suzuki.
VAGThe control module did not receive the expected CAN data bus, SRS signal. This is the manufacturer-specific definition used by Audi.
The control module did not receive the expected Powertrain Data Bus signal. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 18044. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Malfunction Indicator Light (MIL) ON
VolvoThe control module detected that the Engine control module (ECM), internal temperature signal stayed above 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 (10 interpretations). The control module detected a fault associated with the PCM Stack Overrun circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
