Toyota Corolla Cross: 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).

MONITOR DESCRIPTION
When the power supply voltage of the skid control ECU (brake actuator assembly) is a certain value or more, CAN communication of the yaw rate and acceleration sensor (airbag ECU assembly) is valid, and a malfunction signal is received from the acceleration sensor (airbag ECU assembly), the skid control ECU (brake actuator 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.
- Wait for 10 seconds or more. [*]
HINT:
[*]: 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/EPB* / Utility / All Readiness.
*: Electric Parking Brake System
- 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.
