DSC light is on
 

Hi, on my dashboard the DSC light is always on, I took it to a friend of my who has a computer to see whats the error and it gave us C1288 error "PRESSURE BRACK MAIN/PRIMARY CIRCUIT FAILURE" or something like that, when we googled that error it says we have to replace the ABS pump.

However, the ABS works just fine, and the ABS light on the dashboard turns off when I switch the car on.

So what should I do?
