03 Bonneville pulling codes c1214 and c1248

Post by rstein65 »

C1214- system relay contacts or coil circuit open.
C1248- dynamic rear proportion disabled.

Does anyone know how to solve this issue? Recently installed new rear wheel bearing assembly's. Front ones were done 10 months ago.

EBCM (electronic brake control module) is bad, must replace. I sell them if you need one, PM me.
