2004 Mercedes-Benz SL600 Q&A
2004 Mercedes-Benz SL600 Question: My dash warning light stated ABC malfunction, "visit workshop".
I do not fully understand how the ABC system works. - Visitor
this is active body control and is a very complicated system that uses air operated shocks to level the car and control it in an emergency. WIS, which is Mercedes factory Workshop Information System, is updated contantly and is not available to the public. this is not a system that you can diagnose, repair or understand without the investment of many thousands of dollars. - overbys
