Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code Retrieval
Codes can only be retrieved using a diagnostic scan tool. Ensure ignition switch is in OFF position. Connect scan tool to 16-pin Data Link Connector (DLC), located below left side of instrument panel, near center console. Turn ignition switch to ON position. Follow scan tool manufacturer's instructions to retrieve diagnostic trouble codes. Once all codes have been displayed by scan tool, see ABS DIAGNOSTIC TROUBLE CODES (DTC) table for identification of affected component or circuit.

- • 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.
