PRECAUTIONS
a. I n case the' connector related to the automatic shoulder belt
has been disconnected for repairs of the automatic shoulder
belt or its related parts or for repairs of other parts, be sure to
disconnect once the battery and reset the control unit.
If the connector of the automatic shoulder belt control unit or
the connector of front or rear limit switch has once been dis-
connected during repairs, the control unit can enter the failure
mode when the connector is reconnected, making the auto-
matic shoulder belt inoperative.
b. If the automatic shoulder belt fails to operate, be sure to
troubleshoot before disconnecting the battery.
Even if the automatic shoulder belt does not have faulty parts,
it can become inoperative when the shoulder belt anchor is
forced down or the front or rear limit switch is operated
manually. In such case, if you disconnect the battery, the
trouble will be corrected automatically without giving you
the chance to determine its cause.

MOTOR DRIVE CIRCUIT
Operation
The door switch monitors the opening/closing of the door to
rotate the motor in the corresponding (standard or reverse)
direction.
A limit switch, situated at each end of the rail, monitors the
front/rear limit position of the shoulder anchor.
When the door is opened, the motor activates so that the
shoulder belt moves from the rear-limit position (fasten) to
the front-limit position (release) and stops.
When the door is closed, the motor activates so that the
shoulder belt moves from the front-limit position (release)
to the rear-limit position (fasten) and stops.
Malfunction
Motor output timer control
If the limit switch does not activate within 13 seconds after
the motor begins to run, the timer control activates to dis-
connect the motor from its drive circuit.
