LBT 223 / tip clip / Technicians, do you have to prepare a car in your shop for for inspection? If so I’d like to spend a minute on monitors and a few tips and tricks when it comes to running monitors in order to prepare the car for an OBD II inspection. Now keep in mind a couple of pieces of information. Even if you don't do IM in your area, understanding what monitors do and how they run is important for a couple other reasons. I use monitors, for example, to help get the computer to run the tests on the car so I can help to verify my repair. You may also use monitors if you're into mode 6 to do mode 6 work because you need to know how the monitors run in order for the mode 6 to be accurate. So I want to spend just a few minutes here on monitors discussing a couple of pieces that I think will help you if you indeed have to get the monitors to run and show you some of the advantages of getting the PCM to help you along the way.
