General Information

Component Location





General Description

The yaw-rate sensor and later G sensor is installed on the lower floor.
The yaw-rate sensor detects acceleration of the vehicle around its vertical axis, while the G sensor detects lateral acceleration of the vehicle.
When the vehicle is not moving, the G sensor output is approximately 2.5V.

DTC Description

The HECU monitors a signal voltage of either yaw-rate sensor or lateral 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 100ms or the lateral acceleration sensor or yaw rate sensor reference voltage stays in the fault range longer than 200ms or the self test form is against specification during self test.
