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.
Clearing DTCS
To clear DTCs using scan tool, select CLEAR DTCs or CLEAR INFORMATION function. Follow scan tool manufacturer's instructions.
If a scan tool is not available, DTCs can be cleared by disconnecting one of the following power sources for at least 30 seconds:
- Power source to PCM (such as battery pigtail, relay, fuse, etc).
- Negative battery cable (loss of radio presets and/or clock settings will result).
