General Information

Component Location





General Description

Both the yaw-rate sensor and later G sensor is installed in lower floor. The yaw-rate sensor detecting the rotation angular velocity calculates a difference with a target amount of turning, the lateral G sensor detecting slip of the vehicle compensates a target amount of turning. Direction and magnitude of lateral G loaded to vehicle can be known with electrostatic capacity changing according to lateral G. The output voltage of the lateral G sensor is 2.5V when the vehicle is at a standstill.

DTC Description

The HECU monitors a signal voltage of either yaw-rate sensor or later G sensor to detect open or short to battery or short to ground. A failure is detected if the lateral acceleration sensor or yaw rate sensor signal voltage stays in the fault range longer than the 100ms or the lateral acceleration sensor or yaw rate sensor reference voltage stays in the fault range longer than the 200 ms, or the self test form is against specification during self test.
