DTC |
C11782A |
Multi-axis Acceleration Sensor Module "A" (2WD) Signal Stuck In Range |
DESCRIPTION
The airbag sensor 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 sensor assembly) and the range of vehicle speed calculated using each speed sensor.
If the range of the acceleration sensor (airbag sensor assembly) and the range of vehicle speed calculated using each speed sensor are judged to be abnormal when compared to their past memorized range, this DTC is stored.
