Hello, the vehicle brake system is not very hard to depress. Even if depressed with enough effort it is not effective. When the vehicle was scanned, the codes that were found on the ABS were C1252, C1256, C1310.
What could be the problem?

Hi,

All of the codes are related. It could be something as simple as a stuck ABS motor relay or as major as the brake actuator assembly.

I attached diagnostics below. Take a look through them and let me know if you are comfortable performing them.

Take care,

Joe

Good morning, sir.

Please, where is the accumulator pressure sensor located on the ABS actuator?

Hi,

I believe that is integral to the brake actuator assembly. I don't recall seeing a separate sensor at any point.

Thank you, sir.
When I read through some of what you sent earlier, I saw accumulator pressure sensor, since then I have been searching for it on the ABS line, but I couldn't see any sensor. Lol
