P1643 Code défaut de diagnostic (12 interprétations)

The control module registered the fault condition described as "Battery temperature sensor circuit - temperature error". This is the manufacturer-specific definition used by BMW.

The control module detected a fault associated with the Vehicle Theft System Powertrain Control Module in Learn Mode 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.

The control module detected that the signal in the Fuel Pump Monitor circuit stayed below the expected operating range. This is the manufacturer-specific definition used by Ford.

The control module detected that the Battery signal signal stayed above the expected range. This is the manufacturer-specific definition used by Honda.

The control module detected that the Fuel pump (FP) voltage stayed below the expected range. This is the manufacturer-specific definition used by Land Rover.

The control module detected a fault associated with the CAN Link ECM/TCM Circuit Network circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.

The control module detected a fault associated with the Engine control module (ECM) - incorrectly coded/ data bus 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 an interruption (open circuit) in the Accelerator pedal point of resistance sensor information circuit. 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 control module detected a short circuit to ground in the Accelerator pedal hard point switch signal circuit. 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 a short circuit to ground in the Particle filter additive system circuit. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected a fault associated with the Heater relay control circuit 3 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Renault. Renault diagnostic tools (CLIP) report this fault as DF034.

The control module detected a fault associated with the Please check DTC Memory of Electric Load Controller circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 18051. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
