2022年5月20日 · The two codes you have are both from the brake system, and they are related. The C1256 means that the brake fluid pressure isn't being maintained at the proper pressure, and the C1252 means the was running longer than it should have to, trying to keep the fluid pressure up. So it is not very surprising to see those two codes together.
