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 Codes P — Moteur et émissions 600 codes

C Codes C — Châssis, ABS et stabilité 65 codes

U Codes U — Réseau et bus CAN 103 codes

B Codes B — Airbag et SRS 86 codes
