CAT ET was a new serial convey type, although since pc’s will made with serial jacks, many people improved the theory with a USB and also known as this a cat Comm III. This means you are right. This product works with most of PUSSY-CAT motors — Sea, on-highway, and also off-highway. With Sea models, I’m uncertain in which many people squeeze put, but it must be anywhere near the ECM (Typically). This must be the a few pin or in search of pin connector.
To start communicating with your car, you need to have ELM327-based adapter and a OBDII compliant car. Just connect the OBDII adapter to the physical 16-pin OBD connector plug located near the dashboard (typically below the streering wheel), launch the software, and you are ready to go. The connection between the interface and the software can use bluetooth, WiFi, serial port or USB connection depending on the type of hardware you have.
For some jobs, you may also need a tool that can graph or display waveforms. That means buying a digital storage oscilloscope if you don’t buy a high end CAT Caterpillar ET Diagnostic Tool that can do both. Most scan tools display data stream values, which is what the PCM tells it to display. If the PCM is misreading a sensor input or is substituting bogus information, you have no way of knowing without actually testing the circuit or component in question. That’s where a scope comes in handy.
