Toyota Corolla Cross: Multi-axis Acceleration Sensor Module "A" Signal Stuck In Range (C05202A,C11782A)
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.

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.* |
