1999 Pontiac Grand Am C1236

1999 Pontiac Grand Am. Dash lights = ABS and Brake codes c1236. Question = I am just wondering if there is one common problem that occurs when this code pops up and where to start trouble shooting.

Answer:
Have had a few poor connections on the bottom side of the underhood fuse block at the abs fuse and relay terminals causing low voltage.

Also poor grounds on the trans. Bellhousing.1 or 2 bad control modules.
