Hello guys I wanted to update everybody on the unit. OK I used Maxysis on 2004 x350,2005 s type 4.2...The unit is fair on these car models and years..reads and clears codes,epb service,live data,cranks signals etc,fuel pressure,the usual stuff.It scanned the subsystems etc.Next we have the X351 models 2011 XJ, now it does much more,keys,live data,and restting the car values to relearn mode,plus displayed module programming,but ofcourse thats not available yet.Also it allows reset for service,height calibration, and dealership setting and several other modules.The codes that are read are as identical as the OEM SDD tool. The Maxysis will tell you to carry out pinpoint test with sdd for further assistance when you open the code detail query . The 2010-2007 xk models it does pretty darn good,resetting all modules on both CAN BUS lines.Allow you to read the actual oil level from the maxysis screen and shows the vehicle live cluster on the Maxysis in real time...NOW THAT WAS COOL..Also has resetting parameters, live data,module programming,does epc,calibration for headlights, and much more.The data was dead on point when I compared the SDD to the Maxysis because I was looking for accuracy of data as compared to OEM. Guys I am gonna say it again, we have a gem of a scanner...I really have more confidence in this platform..I will check later for more capacity and update the forum.It also does battery registration for the required models,and brake bleeding service....I cant remember if I saw steering angle sensor calibration,but I will update you all later. Until next time happy wrenching, The most impressive thing is speed guys ,by the time my tough book booted my maxysis was done!
