OBD2 Trouble Code (DTC) Reference

Look up check engine, ABS, airbag, and network communication codes — and find the right SEAFLO pump 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 SEAFLO product that matches the required depth.

P P-codes — Powertrain & Emissions 600 codes

C C-codes — Chassis, ABS & Stability 65 codes

U U-codes — Network & CAN Bus 103 codes

B B-codes — Airbag & SRS 86 codes
