2008 uplander showing codes CO111, CO115 and CO120 after trans rebuild and reinstall

Question

vehicle came in with broken band. rebuilt trans and reinstalled and these codes keep coming up. cant get them to clear and see nothing wrong with wiring

Answer 1

C0111 Pump Motor Circuit high

C0115 Right front wheeel speed sensor circuit

C0120 Pump motor relay circuit open

This is for the ABS system , When C0120 occurs this is usually an internal EBCM circuit. This pump motor is known for its poor ground when the battery was reconnected the ECBM ground conection may be be the culprit.
