How to obtain the trouble codes from a 2007 Jeep Grand Cherokee without a scan tool. Note this procedure is pretty much the same for most OBD-II-equipped Chrysler, Dodge and Jeep products made after 1998. Use this procedure to help decide how to fix your vehicle, or as part of the process of deciding on a used vehicle purchase.
Thanks for the video! Now I know how to check for codes myself. I have a 2005 Grand Cherokee. The Jeep's manual tells you how to check if the computer is ready, for say, an emissions test, however, it doesn't explain how to actually check the computer. Thanks for telling me and everyone else how to do this! (:
