Thank you!
Just received the Autel AL619 in the mail. SRS light was on: 2004 Mercedes 320 CLK convertable. Did not download or update the AL619 on the computer (use it as is straight out the box). Plugged the AL619 into the car and entered car info, then hit READ CODE… B1075 CAN Communication Faulty appeared. Then hit ERASE CODE, turned off car for 10 sec and started it. MRS light was OFF.
