Repairs and Inspections Required After a Collision: Service and Repair
SUPPLEMENTAL RESTRAINT SYSTEMS: OCCUPANT CLASSIFICATION SYSTEM: PRECAUTION
CAUTION:
Do not use seat accessories (such as cushions or covers) that cover the front seat. Also, do not modify or replace the upholstery of the
front seat. Doing so may prevent the front passenger airbag system from activating correctly, disable the system or cause the front
passenger airbag to inflate accidentally, and result in death or serious injury.
NOTICE:
*
Replace the occupant classification ECU, occupant detection sensor, seat cushion cover pad, seat cushion cover and seat cushion
seat heater as a 5 part set (see supply set part No.).
*
When the cable is disconnected from the negative (-) battery terminal, the memory settings of each system will be cleared. Because
of this, be sure to write down the settings of each system before starting work. When work is finished, reset the settings of each
system as before. Never use a backup power supply from outside the vehicle to avoid erasing the memory in a system.
*
w/ Navigation system:
*
After the engine switch is turned off, the HDD navigation system requires approximately 6 minutes to record various types of
memory and settings. As a result, after turning the engine switch off, wait 6 minutes or more before disconnecting the cable from
the negative (-) battery terminal.
