5CHECK THE AIRBAG HARNESS.
Measure the voltage between connector (2AB)
in the test harness AB and chassis ground.
Connector & terminal
(2AB) No. 1 — chassis ground:
Is the voltage more than 9 V? Replace the airbag
rear harness RH
with body harness.

tive is not
improved, replace
the occupant
detection system
(seat cushion &
frame assembly),
