What problem did you solve?

We used the CLX000 to read OBD2 data and to "sniff" proprietary OBD2 data (not directly accessible from the OBD standard). The car makers in Brazil have to follow the SAE standard for basic items related to pollution - the rest we have to discover ourselves.

How did you solve it?

We used the CLX000's CAN streaming functionality and Wireshark to stream OBD data and trying to identify the meaning - a tough task! We used the data for vehicle predictive maintenance applications, e.g. identifying soon-to-be exhausted batteries

What BENEFIT has this led to?

The CLX000 is the most practical tool we have for this purpose and it has helped provide us with a much better understanding of the OBD2 codes we could read

"The CLX000 has been the most practical and useful tool amongst similar devices we've tried so far"

Why did you choose the CLX000?

We tried other brands, but they didn't help us much vs. the CLX000
