I have a 2007 SL550 and the other day a had a message on the dash that said ABC malfunction. So I hooked up my scanner and it said ABC no communication with ECU. The car drives perfectly I’m not getting any intermittent flash’s on the dash when I hit any bumps pot holes ECT. Any body have a suggestion where to look or start to figure this out. TIA for any help

ABC computer is behind dash on right side. If I recall you can pop off the side cover and verify connections but it was awhile ago when I removed the module from my car.

I am selling one on eBay from 2005 SL55, if you find the computer is bad. I am on the high end of pricing but module worked when it was removed for coil over conversion.
