DTC |
C135F00 |
Steering Angle Sensor / Yaw Rate Sensor / Lateral Acceleration Sensor Signal Correlation Failure |
DESCRIPTION
The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
When the skid control ECU (brake actuator assembly) detects an abnormal acceleration sensor (airbag sensor assembly) signal, or the control value calculated using the acceleration sensor (airbag sensor assembly), yaw rate sensor (airbag sensor assembly), steering angle sensor and speed sensor are compared and judged to be abnormal, this DTC is stored.

C135F00 |
Steering Angle Sensor / Yaw Rate Sensor / Lateral Acceleration Sensor Signal Correlation Failure |
When the vehicle is being driven in a straight line, the calculated lateral acceleration value based on the speed sensors, steering angle sensor angle and yaw rate sensor (airbag sensor assembly) differs from the value (lateral) of the acceleration sensor (airbag sensor assembly). |
Acceleration sensor (airbag sensor assembly) |
Does not come on |
Brake/EPB |
Output ECU: Skid control ECU (brake actuator assembly) |
PROCEDURE
|
1. |
REPLACE AIRBAG SENSOR ASSEMBLY |
(a) Replace the yaw rate and acceleration sensor (airbag sensor assembly).
