In the car world, there are a lot of acronyms thrown around. Some have become commonplace (ABS, 4WD, and A/C, to name a few), but there are still plenty that send us straight to Google, seeking an explanation for the alphabet soup. While you may have heard of OBD-II (and perhaps can even locate it in your vehicle), you might not know its purpose or potential. Lucky for you, we’ve got all the OBD-II info you need right here, such as CAT Caterpillar ET.
CAT ET Adapter is one vehicle diagnostic adapter that can access Electronic Control Modules (ECMs) from a personal computer. CAT Caterpillar ET Diagnostic adapter enable service technicians to reprogram ECMs, reconfigure control system parameters, fine tune performance or diagnose the root cause of a failure the first time. while before using CAT ET Adapter, you have to license the program with a license key.
When OBD II runs a self-check on a particular component or system, it lets you know by setting a readiness “flag” or indicator which can be displayed on your code reader or scan tool. If OBD II has run all the available monitors and all the monitors have passed — and no faults have been found — the vehicle should pass the OBD II plug-in test. But if all the required monitors have not run, the vehicle can’t be given an OBD II test. The motorist must drive the vehicle and come back again, or take a tailpipe test if that is an option.
