DTC |
C1A46 |
Yaw Rate Sensor |
DESCRIPTION
The skid control ECU receives vehicle stability signals from the yaw rate sensor and sends the signals to the driving support ECU and ECM. If the skid control ECU detects that the yaw rate sensor is malfunctioning, the skid control ECU sends a malfunction signal to the driving support ECU, and the driving support ECU stores DTC C1A46.
