Diagnostic Trouble Code Chart
- If a DTC is output during the DTC check, check the parts listed in the table below and proceed to the "See" given.
- If multiple suspected areas are listed, the potential causes of the symptoms are listed in order of probability in the "Trouble Area" column of the table.
- *1: "Comes on" means the Malfunction Indicator Lamp (MIL) illuminates.
- *2: "DTC stored" means the TCM memorizes the trouble code if the TCM detects the DTC detection condition.
- These DTCs may be output when clutches, brakes, gear components, etc. inside the automatic transaxle 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.
