The Complete Guide To On Board Diagnostic II From old To Newer Automotive
OBD2 GUIDE covers all aspects of the OnBoard Diagnostic II systems on late model domestic and import vehicles. Topics covered include:
* Basic Operation of OBD II on 1995 and newer vehicles
* OBD II system monitors (what sensors & systems OBD II watches, enable criteria for running self-tests, & drive cycles)
* Basic OBD II troubleshooting, including general tips and guidelines
* OBD II troubleshooting help by general type of code or symptom
* Lists possible causes of specific codes, what to check, what PIDS to look at with your scan tool and more.
* Includes helpful information that can save you hours of frustration and chasing dead ends!
* Mode 06 Diagnostic overview (what Mode 06 is and how to access and use it).
* OBD II emissions testing (what is required, tips on how to pass a plug-in OBD II test)
