Yaw Rate/Side/Decel G Sensor SystemBFS000EC
CAUTION:
When the vehicle turns sharply, such as a spin turn, accel turn, or drift driving, while the VDC function
is OFF (VDC OFF indicator lamp turns on), a malfunction may occur in the yaw rate/side/decel G sen-
sor system, so in this case, restart the engine, and if it recovers normally, there is no malfunction.
Always erase memory after that. Refer to BRC-58, "
ERASE MEMORY" .
