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.
Reading Readiness Code
Readiness code is returned to 0 1 1 0 1 1 0 1 if DTC memory is erased, voltage supply to ECM is lost, or a new ECM is installed. To read readiness code, connect scan tool to DLC. DLC is located left side of steering column. Turn ignition on. Follow scan tool manufacturer's instructions and read Readiness Code. See Figure. Readiness code should display 0 0 0 0 0 0 0 0. If readiness code displays as specified, testing is complete. If readiness code does not display as specified, generate readiness code. See GENERATING READINESS CODE .
