l If the driver fastens the seat belt with the
ignition switch placed in the “ON” position, the
seat belt switch in the seat belt buckle is turned
“ON” to operate the seat belt solenoid in the
retractor.
lThis will reduce the seat belt rewinding torque
to minimize a sense of oppression given by the
belt.
lOwing to the timer function of the ETACS unit,
the seat belt solenoid is kept in operation for 30
seconds after turning off the ignition switch,
with due consideration to elimination of the
sudden rise in a sense of oppression caused by
the belt immediately after the ignition switch is
turned off.

TROUBLESHOOTING GUIDE
INPUT CHECKUsing the multi-use tester or voltmeter, check whether or not
the input signals from each switch are being input to the
ETACS unit.
(1) Connect the multi-use tester to the diagnosis check
connector located at the right side of the junction block or
connect the voltmeter between the ETACS terminal and
the ground terminal.
(2) Check if the buzzer of the multi-use tester sounds or the
needle of the voltmeter moves when each switch noted
below is operated.
If the buzzer sounds or the needle moves, the input signals
are being input to the ETACS unit, so that switch can be
considered to be functioning normally. If not, the switch or
switch input circuit is faulty. Check the switch and the
switch input circuit.
