The OBD-II port is going to be the best place to interface with the vehicle. This is where you'd pull the information you are talking about. Your Telematics unit is probably just tying in directly to the wiring instead of the port to leave it open for smog testing or other maintenance testing. Is it going to be a problem if we start occupying the OBD ...

Mode 6 data is not ...

We find FF so useful that we retain it on the customers invoice in case the same code sets later. It is also very helpful when used in conjunction with a test drive on intermittent faults. It tells exactly how to duplicate the conditions under which the fault set. There are times when its limit of setting on only one code is frustrating because it is not ...

To do this remove both battery cables and connect them together for 10 minutes. While they are apart take the opportunity to clean off any the acid.

The short answer is: no - not without the manufacturer's diagnostic tools. The long answer is: maybe. Modern cars have most (if not all) exterior and interior lights controlled by the body control module (BCM). Most (if not all) switches are connected to the BCM as well. This provides a lot of flexibility. A prime example is if you leave your headlights ...
