OBD2 Trouble Code (DTC) Reference

Look up check engine, ABS, airbag, and network communication codes — and find the right FOXWELL scanner to diagnose them.

Diagnostic trouble codes (DTCs) point to the system that failed — not always the part to replace. P-codes cover engine and emissions; C-codes point to ABS and chassis; U-codes indicate CAN network communication faults; B-codes relate to airbags and SRS. Use this reference, then scan with a FOXWELL tool that matches the required depth.

P P-koder — Motor och emissioner 600 koder

C C-koder — Chassi, ABS och stabilitet 65 koder

U U-koder — Nätverk och CAN-buss 103 koder

B B-koder — Airbag och SRS 86 koder
