Efter replacing the Abs pump I got these wrong codes. C1203 and C1345. either Techstram could not delete they nor bleeding or Linear Solenoid Valve Offset Learning. because of. C1203 could not communicate with ECU. I tried manual bleeding so drove a short trip. fantastic, after the short trip C1203 disappeared and everything was ready for Linear Solenoid Valve Offset Learning. The problem was solved.
