CUSTOMER CONCERN
Customer states the 12-volt battery went dead during an alignment and DTCs C1203 and C1345 are now stored.
CAUSE
Loss of battery voltage erased the linear-solenoid valve offset calibration, leaving the brake-control system incorrectly configured.
CORRECTION
Perform linear-solenoid valve initialization and calibration, complete yaw-rate sensor calibration as required, clear DTCs C1203 and C1345 and verify brake-system operation.
