ABC Malfunction
I just got a message on the dash ABC malfunction. So I used my icarsoft and it said ABC no communication with ECU. Car drivers perfectly no sagging no leaks nothing. 2007 SL550 45000 miles. Looking for some advice on what could be going on. TIA Dave

Check that no pins are pushed back in the diagnostic socket. R230s use several different pins to read different modules, so it might read most of them fine and still have a bad pin.
