RM38T0EC _54 Brake _112606 BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS _0608077 ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HEV Model) C

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS  ELECTRONICALLY CONTROLLED BRAKE SYSTEM(for HEV Model)  C11782A  Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range  


DESCRIPTION

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

The skid control ECU (brake actuator assembly) memorizes the range of the acceleration sensor (airbag ECU assembly) and the range of vehicle speed calculated using each speed sensor.

This DTC is stored when the acceleration sensor (airbag ECU assembly) value is abnormal when the vehicle is accelerating or decelerating.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL DTC Output from Note
C11782A Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range From the time the vehicle starts off until it stops, the longitudinal acceleration sensor value fluctuates 0.5 m/s2 or less during acceleration/deceleration between 1.47 m/s2 and 12 m/s2, or the value always remains 36% or less of vehicle acceleration for 1 to 2 seconds.* Acceleration sensor (airbag ECU assembly) Does not come on Brake/EPB Output ECU: Skid control ECU (brake actuator assembly)

*: Varies depending on the vehicle driving conditions.
