MONITOR DESCRIPTION
C053D (Case 1):- When the master cylinder pressure sensor and CAN communication are normal, the vehicle is being driven at a certain speed or more, and the master cylinder pressure is too high with respect to the brake pedal stroke amount as detected by the electric brake booster (brake booster with master cylinder assembly), the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.
- When the master cylinder pressure sensor and CAN communication are normal, the vehicle is being driven at a certain speed or more, and the master cylinder pressure is too low with respect to the brake pedal stroke amount as detected by the electric brake booster (brake booster with master cylinder assembly), the electric brake booster (brake booster with master cylinder assembly) illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Turn the ignition switch to ON (READY) and turn the GTS on.
- Drive the vehicle at a speed of 3 km/h (2 mph) or more for 1 second or more. [*1]
- Enter dealer mode or inspection mode, and drive the vehicle at a speed
of 10 km/h (6 mph) for 1 second or more. [*2]
HINT:
[*1] to [*2]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Chassis / Brake Booster / Utility / All Readiness.
- Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
PROCEDURE

Yaw Rate Sensor Circuit Intermittent (C00631F,C006396,C05201F,C052096,C11781F,C117896)
DESCRIPTION
The airbag ECU assembly has a built-in yaw rate and acceleration
sensor and detects the vehicle condition.
These DTCs are stored when the skid control ECU (brake actuator
assembly) receives a malfunction signal from the yaw rate and acceleration sensor
(airbag ECU assembly).
Checking Monitor Status
CHECKING MONITOR STATUS The purpose of the monitor result (mode 06) is to allow access to the results of on-board diagnostic monitoring tests of specific components/systems that are not continuously monitored. Examples are catalysts and evaporative emissions (EVAP) systems.
