RM3660EC _54 Brake _080770 BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS _0392591 ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HV Model) C

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HV Model)  C00631C  Yaw Rate Sensor Circuit Voltage Out of Range  


DESCRIPTION

The airbag sensor with ECU assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.

The skid control ECU (brake actuator assembly) calibrates the sensitivity of the yaw rate sensor (airbag sensor with ECU assembly) based on signals from the steering angle sensor and speed sensors.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL DTC Output from Note
C00631C Yaw Rate Sensor Circuit Voltage Out of Range The skid control ECU (brake actuator assembly) detects an abnormal yaw rate sensor (airbag sensor with ECU assembly) sensitivity during calculation. Yaw rate sensor (airbag sensor with ECU assembly) Does not come on Brake/EPB Output ECU: Skid control ECU (brake actuator assembly)
