PRECAUTION
GENERAL PRECAUTION
(a) The following conditions may be interpreted as a malfunction even though they are normal operation:
(b) Zero point of the occupant classification sensors may deviate in the following situations. To ensure sensor accuracy, be sure to perform Zero Point Calibration.
HINT:
As the zero point is not automatically stored in a new occupant detection ECU, it is necessary to perform zero point calibration after replacing the occupant detection ECU.
HINT:
As the weight of accessories will be added to the weight of the occupant, the system will not be able to perform classification accurately.
HINT:
As the seat frame will warp slightly when the bolts that are used to install the front passenger seat are tightened, the load applied to the occupant classification sensor will change and the system will not be able to perform classification accurately.
HINT:
As the seat frame will warp slightly when the bolts that are used to install the front passenger seat are tightened, the load applied to the occupant classification sensor will change and the system will not be able to perform classification accurately.
