Your best bet is to pull codes from the roof controller. A generic OBDII scanner won't do that - you need a specialized tool. MBZ's SDS (Star Diagnosis) is the best choice and a "Chinese clone" unit can be bought for under $500, pre-installed on a (used) laptop. There are also some less capable and less expensive hand-held units like the iCarsoft i980 and MBII, and the Autel MD802 Elite.
