I replaced my dash cluster due to no display on the dic or climate control. I am now getting a airbag warning light with the following code. I ran a diagnostic ans this is the code: R055 .................................................. ........ DERM Incompatibility
After getting this code I unplugged the new cluster and tried the old one. The warning light cycled and then went out like it should. I unplugged the battery and connected the new one again. Same code and service air bag in dic. It went off once on the first day that I installed it and I reset all codes. It came back on the next time that I started it and remains. Please help.

Thanks
