1 CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the occupant detection control mod-
ule and belt tension sensor.
Is there poor contact? Reconnect the
connector. If the
fault is not fixed,
replace the airbag
harness.
Go to step 2.
2CHECK THE BELT TENSION SENSOR.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the belt tension sensor connec-
tor (AB56) from the airbag harness.
3) Connect the test harness AC to the con-
nector (AB56).
4) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for approximately 6
seconds and go off?
