C0371

DTC C0371/71 YAW RATE SENSOR OUTPUT SIGNAL MALFUNCTION (TEST MODE DTC)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The skid control ECU receives signals from the yaw rate and deceleration sensor via the CAN communication system.

The yaw rate sensor has a built-in deceleration sensor.

If there is trouble in the bus lines between the yaw rate and deceleration sensor and the CAN communication system, the DTC U0123/62 (lost communication with yaw rate sensor module) and U0124/95 (lost communication with lateral acceleration sensor module) are output.

These DTCs are also output when the calibration has not been completed.
DTCs C1279/79 and C0371/71 are output only in the test mode (SIGNAL CHECK).
