P1773 — Malfunction of the ABS

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Generic

About P1773

P1773 is a manufacturer-specific powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1773 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

This powertrain related DTC is typically set when the transmission control module (TCM) or engine control module (ECM) detects a fault or malfunction signal from the ABS system that affects driveline or torque management functions. The fault is generally set via a data link communication rather than by direct sensor monitoring. It usually indicates that the ABS system has a fault that could impact traction control, torque reduction strategies, or shift behaviour. Because the trigger is a message from the ABS module, the first step is to retrieve and address the ABS module own fault codes.
