first ,you have to make sure the Maxicheck Pro has installed the TPMS software. Then, you can use TS401 to trigger the TPM sensors and got the sensor info. The last step is to use Maxicheck to write the sensor ID and position into your vehicle ECU.

 I just bought both of them last week.  Autel has been fooling us because they take out the tpms feature.  The company knows that people can save more if they buy the ts 401 and maxi check pro with the tpms reset. Than buying the expensive ts501 and ts601.
