WE NEED CODES OR MORE HISTORY TO HELP OUT.THAT LIGHT WILL RESET AUTO. WHEN PROBLEM IS REPAIRED WHATEVER IT MAY BE.
How can I get the codes? Is there any device that I can use to read that? The dealership charges $100 bucks or more just to use the reader.
its a special reader you may have to go or call around and get diag est. alt of shops will read codes for free but diag is extra
The codes are: B1406, B1102, B1101. Is there a way to fix them by myself?
