Hello! I have MB SL 350 year 2006 and the battery
warning light is on and visit workshop. On the diagnostic tool we got three codes under eloctronic stability programe (6210 abs
control system, 6230 esp operation, 5B13 test battery control module). These codes are parmanent and cannot be deleted. When the engine is on the voltage on both batteries is around 14V. We are assuming battery control module in the rear right side of the trunk, but how to be sure? Thank you
JA: Just to clarify, what are the exact lights you're talking about?
Customer: just for the battery (red one)
JA: Are you fixing your SL yourself? What have you tried so far?
Customer: we checked both batteries and all the fuses, measure the voltage on both batteries, do the diagnostic...
JA: Anything else you want the mechanic to know before I connect you?
Customer: Is there any wiring scheme (voltage input or output) of N82 (battery module) that i can check to see if N82 is bad?
