The control module did not receive the expected Voltage to Vehicle Load Control Module Fan signal. This is the manufacturer-specific definition used by Ford.

The control module detected a fault associated with the Engine control module (ECM) - unexpected reset circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.

The control module detected improper operation of the Engine coolant blower motor relay high speed circuit. This is the manufacturer-specific definition used by Kia.

The control module detected a fault associated with the Check Engine MIL 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.

The control module detected improper operation of the Engine control module (ECM). This is the manufacturer-specific definition used by Opel.

The control module detected the fault condition "ESP request incoherent" for the CAN communication. 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.

The stored code identifies a fault of the ECU internal fault. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.

The control module detected the fault condition "ESP request incoherent" for the CAN communication. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected the fault condition "Safety" for the Incorrect ESP request. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected improper operation of the Immobilizer control module - antenna. This is the manufacturer-specific definition used by Suzuki.

The control module detected that the CAN data bus, TCM state or value did not match what was expected. This is the manufacturer-specific definition used by Audi.

The control module received a network message for Powertrain Data Bus whose content was implausible compared with other data. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 18033. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

The control module detected that the Malfunction indicator lamp (MIL) signal stayed below the expected range. This is the manufacturer-specific definition used by Volvo.
