PRECAUTION PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL
NOTICE: When
disconnecting the cable from the negative (-) auxiliary battery
terminal, initialize the following systems after the cable is
reconnected: |
System | See Procedure | |
Lane Departure Alert System (w/ Steering Control) |
 | |
Intelligent Clearance Sonar System | |
Parking Assist Monitor System | |
Panoramic View Monitor System | |
Pre-collision System | |
Lighting System (for HV Model with Cornering Light) |
GENERAL PRECAUTION (a) The following conditions may be interpreted as a malfunction even though they are normal operation:
- An object is placed on the front passenger seat and the system judges
that an adult is seated. As the occupant classification system detects
and classifies occupants based on weight, the system may detect an
object placed on the seat cushion as an adult passenger depending on its
weight.
- Pressure is applied to the front passenger seat and the system judges
that an adult is seated. As the occupant classification system detects
and classifies occupants based on weight, the system may detect an adult
passenger if pressure is applied to the seat cushion by hands, etc.
- Illumination of the passenger airbag ON/OFF indicator does not change
immediately after a passenger is seated or leaves the vehicle. To
prevent the classification judgment from changing when a passenger
changes their seating posture, a certain amount of time is required to
detect and classify an occupant when the calculated weight changes.
Therefore, there will be a time lag between when a passenger is seated
or leaves the vehicle and when the system detects the occupant.
(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.
- The occupant detection ECU is replaced.
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.
- Accessories (seatback tray, seat cover, etc.) are installed.
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.
- The front passenger seat is removed from the vehicle.
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 sensors will change and the system will not be
able to perform classification accurately.
- Any of the bolts that are used to install the front passenger seat are removed and reinstalled.
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 sensors will change and the system will not be
able to perform classification accurately.
- The passenger airbag ON/OFF indicator ("ON") illuminates when the front passenger seat is not occupied.
HINT:
If
any load or pressure is applied to the occupant classification sensors,
the system will not be able to perform classification accurately.
- An occupant classification sensor collision detection DTC is output due to an accident or a collision.
