Diagnostic Trouble Code Chart

If a DTC is displayed during the DTC check, check the parts listed in the table below and proceed to the page given.

HINT:

  • *1: Comes on MIL (Malfunction Indicator Lamp) light up
  • *2: "DTC stored" mark means ECM memorizes the malfunction code if the ECM detects the DTC detection condition.
  • This DTC may be output when the clutch, brake and gear components etc. inside the automatic transmission are damaged.

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.
