CUSTOMER CONCERN
Customer requests diagnosis because the skid-control system will not complete calibration and stores DTCs C1345 and C1368.
CAUSE
The skid-control ECU had not completed the linear-solenoid-valve offset learning. Calibration required a properly bled brake system, cleared learning memory and at least 12.6 volts at the skid-control ECU.
CORRECTION
Perform the bidirectional brake bleeding procedure, clear the skid-control learning memory and perform the linear-solenoid-valve offset relearn with the parking brake released, vehicle level and steering wheel centered.
