The code 43 should be low coolant. The code 46 should be battery voltage low. Code 54 should be speed sensor fault. Code 25 interestingly enough is no codes.
Since the faults seem to be tied to the passing through the dip, I would be checking the connections at the DDEC unit and the Transmission ECU.
