P1703 Diagnostic Trouble Code (9 interpretations)

The control module detected a fault associated with the Brake On/Off Switch Out of Self - Test Range 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.

Ford documents P1703:00 (no sub type information) for its 2024-2025 gasoline-engine OBD monitor strategy as brake switch out of self-test range. This three-byte interpretation is application-specific and identifies the detected monitor condition rather than a confirmed failed component.

The control module detected an open circuit or short circuit condition in the Throttle Position Sensor(TPS) circuit. This is the manufacturer-specific definition used by Hyundai.

The control module detected a fault associated with the Transfer box link - signal line circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.

The control module detected a fault associated with the Brake pedal position (BPP) switch - torque converter - out of self - test range 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 Transmission Control Module ROM circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Nissan.

The stored code identifies a fault of the Fault. Documented for the AL4 automatic gearbox ECU on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.

The stored code identifies a fault of the Fault on the accelerator pedal position information not received by the CAN (Engine ECU). Documented for the AM6/AT6 automatic gearbox ECU 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 improper operation of the Shift solenoid (SS) low clutch timing circuit. This is the manufacturer-specific definition used by Subaru.
