TuningBot DTC Database · v4.37.15
15 manufacturer-specific interpretations across 14 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Loss Of VTD Serial Data 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.
DodgeThe control module detected a fault associated with the Engine control module (ECM) - supply 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 Dodge.
FordThe control module detected a fault associated with the Engine control module (ECM) 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.
Incorrect programming
KiaThe control module detected improper operation of the Electronic throttle system (ETS) control module. This is the manufacturer-specific definition used by Kia.
Land RoverThe control module detected that the signal in the Engine coolant thermostat circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected a communication fault involving Data bus, cruise control module on the vehicle network. This is the manufacturer-specific definition used by Lexus.
Mercedes-BenzThe control module detected a fault associated with the IFI Control Module N37 Supply 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 Mercedes-Benz.
NissanThe control module detected improper operation of the Ignition key/immobilizer control module communication. This is the manufacturer-specific definition used by Nissan.
OpelThe control module detected that the Immobilizer control module / multifunction control module communication state or value did not match what was expected. This is the manufacturer-specific definition used by Opel.
PSAThe control module detected the fault condition "ECU internal fault" for the Engine ECU. Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
SuzukiThe control module detected a communication fault involving Steering lock on the vehicle network. This is the manufacturer-specific definition used by Suzuki.
ToyotaThe control module detected a communication fault involving CAN data bus, cruise control module on the vehicle network. This is the manufacturer-specific definition used by Toyota.
VAGThe control module judged the Engine oil temperature (EOT) behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Audi.
