OCCUPANT DETECTION SYSTEM (DIAGNOSTICS)
3. General Description
A: CAUTION
1) If the seat cushion cover is removed or replaced,
make sure to perform passenger detection system
adjustment after installing the seat to the vehicle.
<Ref. to OD(diag)-18, SYSTEM CALIBRATION
(REZEROING), OPERATION, Subaru Select Mon-
itor.>
Failure to do so may cause improper operation of
the occupant detection system.
2) The passenger detection system (passenger
seat only) control unit and the passenger detection
sensor are fixed to the seat cushion frame. Never
remove the passenger detection control unit or the
pressure sensor from the seat cushion frame.
3) Do not replace the seat cushion pad by itself. Al-
ways replace the seat cushion pad and frame as-
sembly as a set. The seat cushion pad and cushion
frame are adjusted as a set at the time of manufac-
ture. If cushion pads and cushion frames are com-
bined from those of other vehicles or other sets, the
passenger detection system may not operate prop-
erly.
4) If the seat cushion cover is removed, make sure
to replace the wire on the seat cushion side with a
new wire.
5) Never connect the battery in reverse polarity.
Occupant detection system may be destroyed in-
stantly.
6) Do not disconnect the battery terminals while the
engine is running. A large counter electromotive
force will be generated in the generator, and this
voltage may damage electronic parts such as occu-
pant detection control module.
7) Before disconnecting the connectors of each
sensor and control module, be sure to turn the igni-
tion switch to OFF and wait for 20 seconds or more.
Occupant detection control module may be dam-
aged.
8) All passenger detection system parts are preci-
sion components. Do not drop them.
CAUTION:
• Do not use the electrical test equipment on
the airbag system wiring harnesses and con-
nector circuits.
• Be careful not to damage the airbag system
wiring harness when servicing the occupant
detection system.
• Refer to "Airbag System" when repairing the
occupant detection system. <Ref. to AB-3,
CAUTION, General Description.>
