DTC C2111: Sensor Power Supply Circuit
DTC C2112: Sensor Power Supply Circuit (Brake Fluid Pressure Sensor)

M13506100062USA0000010000

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagnosis,
diagnose the CAN bus lines. (Refer to GROUP 54D, Trouble
code diagnosis P.54D-17).

CIRCUIT OPERATION
When the brake pedal is depressed, the brake fluid pressure
sensor integrated in the hydraulic unit detects the brake fluid
pressure applied from the master cylinder, converts the pressure
value into voltage signal, and outputs it.

DTC SET CONDITIONS
This diagnostic trouble code is set when the voltage applied to
the pressure sensor is not within the standard value range.

PROBABLE CAUSES
ASC-ECU malfunction
