My ABS, ESP and BAS lights have been on since I purchased my CLK 320 Convertible A208 a year ago. I have tried everything mentioned in these forums. So, I purchased a Craftsman 1681 scan tool, it is the same as an Innova 5100. Both of these are compatible with my vehicle and should read the ABS codes. The scanner will read everything else on the vehicle, however, when I ask it to read ABS codes it tells me that I am not connected to the vehicle!. I am connected because I just ran a full diagnostic! Called support and they have no idea except to say that my vehicle is not communicating with the scanner when checking ABS. Any help in this issue would be appreciated.
ABS/ESP/BAS codes have to be scan thru the 38 pin port. You will need a compatible multiplex
adapter. Cheap Ebay ones will not work.
Did you check your battery voltage? Resync steering angle sensor?
