For universal applications, we have chosen the most common communication protocol used for powertrain data.

We opt for the CAN protocol with a 11 bit ID and a Baud rate of 500 Kbit/sec.


Not all read-outs are supported by the car manufacturer.

Therefore, it is mandatory to check this (or have it checked) prior to ordering one of our CAN-based products.

If you send us the KempoTronic product that you want and VIN number of your car by email to support@kempotronic.com, we can check this for you.


Should you have bought the KempoTronic product without having checked this first and the read-out is not supported by the car manufacturer, the diagnostic LED will go on and you will get a Diagnostic error message :

DIAG : NOT supported by this car


In that case, we cannot be held responsible.


Specifically for the Cooling Managers (CLM) :

Most cars will support Engine Coolant Temperature and Engine Intake Temperature read-out. Only a few cars will support Engine Oil Temperature read-out.

In case the read-out is not supported by the car manufacturer, you can always opt for another NOT CAN-version :

- sensor pick-up from an existing sensor

- kit with an extra sensor (included)
