Driving Support DTC Troubleshooting Index (3.0L Engine) (2022 2023 2024)
NOTE:
- The DTC troubleshooting index shows DTCs that are stored in the integrated driver support system. Each function of the integrated driver support system operates differently according to which DTC is stored. The functions of the integrated driver support system that operate when these DTCs are stored and their conditions can be confirmed with the table below:
: Indicator ON, and operation stopo: Operation stop
- For the millimeter wave radar, different indicators may be lit for the same DTCs depending on which functions are in operation at the time the DTCs are stored. Make sure to check following DTCs with asterisks before troubleshooting them.
NOTE: For details on the functions of indicators, and operation stop, refer to "How to Troubleshoot Information".

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.
