Diagnostic Trouble Code Definitions
See DTC IDENTIFICATION (ACCENT, ELANTRA & TIBURON) or DTC IDENTIFICATION (SONATA) table or refer to appropriate DTC IDENTIFICATION table in appropriate SELF-DIAGNOSTICS article. Once DTC has been identified, proceed to appropriate diagnostic procedure in appropriate SELF-DIAGNOSTICS article. Repair condition which set DTC(s), beginning with lowest number first, then in ascending order.
NOTE:
Not all codes apply to all models.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
