Caddy Gripe

Some owners of 2014 Cadillac CTS sedans may comment that the power driver seat is inoperative. They may also complain that the power outside mirror is inoperative. Do not replace the memory seat module (MSM) for this concern.

Using the GDS2, request DTC information from the memory seat module. It may report “no communication” with the MSM. Other modules may set U0208 (loss of communication with MSM.

Engineering is aware of this concern and is working on a long-term resolution. In the meantime, the memory seat module logic fuse can be removed for at least 10 seconds. This action will remove power from the MSM and reset the module. After the module has been reset, power seat and mirror function will return.
