This bulletin applies to 2013-2014 Chevy Spark vehicles. According to Motologic’s site, a dealer technician may not be able to perform the BCM Setup or Config using GDS2 after adding options (i.e. fog lamps) and/or programming/updating the BCM software. A no-comm message may be found or the procedure cannot be completed.
If the concern is exhibited in GDS2 only, the correction is to locate session history in GDS2 and delete the session history for the vehicle VIN. When rebuilding the vehicle in GDS2, you must select with WHB.
