I suggest you check the wiring that goes to the EBCM (ABS control unit) inside the engine bay. The C0900-00 Control Module Power Circuit DTC suggests the EBCM might be having power issues.
Have you cleared the DTC's? If so, did they return?
How old is your car's battery? I suggest you have it load-tested. You can do that at AutoZone etc. Remember to disconnect both battery cables before connecting the load tester.
After you: *reset the DTC's; *load test your battery *check your EBCM wiring for damage; if all is OK on these 3 fronts, then I would suggest you check the acceleration sensor. I don't have any experience with that besides knowing it is a quite sensible/fragile part. But there's a good chance the problem is one of the 3 items I pointed out.
