OCCUPANT DETECTION SYSTEM (DIAGNOSTICS)
3. General Description
A: CAUTION
1) Never remove the occupant detection control
module, occupant detection sensor and seat cush-
ion from seat frame because the occupant detec-
tion system is integrated into seat frame as one
unit.
2) Always perform “system calibration (Rezeroing)”
when removing or removing and disassembling the
passenger’s seat. CALIBRATION (REZEROING), OPERATION,
Subaru Select Monitor.>
3) Never connect the battery in reverse polarity.
•Occupant detection system may be destroyed in-
stantly.
4) Do not disconnect the battery terminals while the
engine is running.
•A large counter electromotive force will be gener-
ated in the generator, and this voltage may damage
electronic parts such as occupant detection control
module.
5) 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.
6) Every A/C-related part is a precision part. Do not
drop them.
7) Airbag system wiring harness is routed near the
A/C control panel and junction box.
CAUTION:
•For airbag system, yellow-colored wiring har-
ness and connectors are all used. Do not use
the electrical test equipment on these 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. 4, CAUTION, General Description.>
B: INSPECTION
Measure the battery voltage and check electrolyte.
Standard voltage: 12 V
Specific gravity: Above 1.260
