Before replacing a part
Record codes and freeze-frame data. Check battery condition, related codes and visible wiring or hose damage. Follow the vehicle's diagnostic procedure and test results before replacing parts.
Can I keep driving?

Stop in a safe place and seek assistance when control or engine safety is affected. Follow the vehicle handbook.
