Diagnostic Trouble Code Chart
HINT:
- Using SST 09843-18040, connect terminals TC and CG of the DLC3.
- If no abnormality is found when inspecting parts, inspect the ECU and ground points for poor contact.
- If a trouble code is displayed during the DTC check, check the circuit listed for that code.
- When 2 or more DTCs are recorded and the problem is not identified, perform circuit inspection of the other DTCs.

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.
