• On the scan tool, click on the read button to display the error messages or codes. On display, do not forget to write the error codes or messages down just as they appear on the screen of the scan tool.
• The retrieved codes or messages will serve as a guide for subsequent repairs or corrections.
• Now that you have retrieved the error codes, the next step is to clear or erase them. To get rid of the error codes, click on the clear or erase button on the scan code.
• Once all the error codes are wiped off, the check engine light automatically goes off. While doing this (wiping the codes off), do not forget to leave the ignition on.
