only have this tool since june 2015 I am really disapointed

steering angle  calebration  and    STEERING ANGLE  DATA WAS   TAKEN  OUT ON  ALL GM CARS.  ALL OF THEM   I AM  VERY UPSET WITH THIS.

 what version of gm are you running? Did you back up previous versions? Try reinstalling older version.  And..... as support would say Send in a data log.....

 i have no old versions.  i am updated  to present.     i wish  i stopped  up dating  about 4 months ago.  and data logs  for what . autel knows what they took out.     i just hope  they win in court  and   make the maxisys  the best aftermarket  scanner  out there again  like it once was. 

This tool use to be really good, nowdays with the updates and downgrading is useless. They took away lot of functions.

Hello I never get the chance to use this tool when it was good
I really like this tool it hope thay win in court . That we may get all our function
back . That may be reasion we are all downgraded

  AES Wave website lists a handy  Autel"s  Update Coverage chart in  detail of what the  MAXI SYS software should be able to support in special functions of each make and model.Please double check the version level to see if it is the most current update level. It gives alpha numeric  codes  that you can refer to what they are in charts in the later pages of the corresponding coverage PDF ! Just click the button of the manufacturer. Might come in handy to see what Maxi Sys should be able  or not able to do beforehand.
