DTC C1246/46 Master Cylinder Pressure Sensor Malfunction
DESCRIPTION
Master cylinder pressure sensor is connected to the skid control ECU in the actuator.
INSPECTION PROCEDURE
1 READ VALUE ON INTELLIGENT TESTER (MASTER CYLINDER PRESSURE SENSOR)
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine.
(c) Select the DATA LIST mode on the intelligent tester.
ABS / VSC:
(d) Check that the brake fluid pressure value of the master cylinder pressure sensor indicated on the intelligent tester, changes when the brake pedal is depressed.
OK: Brake fluid pressure value should change.
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).
REPLACE BRAKE ACTUATOR ASSEMBLY
2 INSPECT SKID CONTROL ECU (STP1 TERMINAL)
(a) Disconnect the skid control ECU connector.
(b) Measure the voltage according to the value(s) in the table below
Standard voltage
NOTICE: When replacing the brake actuator assembly, perform zero point calibration (See page BC-70).
REPLACE BRAKE ACTUATOR ASSEMBLY
