    Re: service engine light

    What year is your DHS - it makes quite a difference in how we advise you to start diagnosis, but .......

    Use the sticky post, just above this thread, titled "How to pull codes" - Diagnostic Trouble Codes - from your car's built-in code reader/scanner/memory. Use the appropriate year group and pushbutton sequence to turn your DIC into a DTC readout, write down all found codes and whether each is Current or History - then return to the sticky to open the link to the correct year lists of code definitions. Decipher all your codes and post it all here.

    ?? DIC ?? DTC ?? - Study the sticky post ^^^ Acronyms. (Get the idea that ALL stickys are important background info ???)

    Update your profile to look sort of like other members login headers - the info sure helps. The Settings tab ^^^, edit profile.
