Search communication faults, circuit problems, configuration errors, crash-event records and powertrain concerns. Bring us the complete scan report and the work already done so we can help your shop plan the assessment.

Keep the complete fault code.
U3000 is a control-module fault. U3000:41 and U3000:49 describe different reported conditions. The module that stored it, vehicle details and full suffix determine which diagnostic procedure applies. A description does not prove that the named part has failed.
For three-byte DTC formats, a suffix can identify an open circuit, short to ground, voltage fault, memory failure or mechanical condition. Suffixes vary with diagnostic format and manufacturer. We show supported examples instead of applying one suffix table to every vehicle.
Crash data is a separate concern.
A crash-event record, a deployed pretensioner and a restraint-circuit fault need different assessments. A reset is not a substitute for manufacturer-required replacement or post-collision inspection. Send the module part number, collision history and full scan report to confirm the available service.

This reference combines the openly licensed python-OBD P/U-code list with selected OEM and Ross-Tech application examples. It is not the complete current SAE annex or a complete manufacturer database. General descriptions are not individually validated for every model. Body, chassis and crash-event coverage is selected, not exhaustive. Vehicle coverage and the work MSBG can perform are confirmed before booking; a mechanical code appearing here does not establish repair availability.
Each result links to its source. Open reference data is derived from python-OBD revision e3be50335f7b96e53a02a1c0dbb9f888d9744c2f, under GPL-2.0-or-later. The upstream list is older than current OEM coverage.
