TROUBLESHOOTING DIAGRAMS (TSD)
• If you have a problem and do not know the cause, follow
the specific Troubleshooting Diagram (TSD) step by step.
• If parts are required, use only original SCHROTH parts.
They are designed especially for the harness belt system.
Unauthorized parts can cause malfunction of the harness
belt system or damage your vehicle.
• For your safety: Repairs to the retractor and sensor are
strictly prohibited!
• If you cannot solve the problem after following the
applicable Troubleshooting Diagram, contact your dealer
or importer.
Never use the harness belt system if it does not function
properly.
Safe driving may be impossible and the effectiveness of
the harness belt system will be impaired.

How the SCHROTH asm-autocontrol retractor works
The SCHROTH
asm-autocontrol is the first harness belt
system for street use to offer the comfort, convenience and
safety of an automatic retractor. The SCHROTH
asm-
autocontrol gives you greater freedom of movement to reach
vehicle controls while providing the benefits of a harness
system. The heart of the SCHROTH
asm-autocontrol
harnessbelt is an electro-magnetically operated emergency
locking retractor.
The retractor is both, webbing and vehicle sensitive. It will lock
when belt webbing is unreeled too fast. It will also lock when
forces act on the vehicle from any direction during an accident
or during extreme driving maneuvers such as heavy braking or
during sharp cornering. The retractor will also lock if the
vehicle is tilted more than 25 degrees.
A sensor controls the electro-magnetic operation of the
retractor. In order to work properly and react to forces coming
from different directions, the sensor must be installed vertically.
If the sensor is not installed vertically, the retractor will be more
sensitive to forces applied to the vehicle from one direction
than from another and the system will not work properly.
The retractor will unlock allowing webbing to be unreeled and
you to move as soon as current flows to the electric-magnetic
system in the retractor from your car’s 12-volt electrical
system. Electrical current flows whenever the ignition is
switched on.
When forces act on the vehicle that trigger the sensor, the flow
of current to the electro-magnetic system of the retractor is
interrupted and the retractor locks. Webbing can no longer be
let out, but the retractor is still able to take up slack in the
webbing.
For your safety, the system was designed to lock up whenever
the flow of current to the retractor is interrupted. For that
reason the retractor is locked when the ignition is turned off.
The correct sequence for buckling the SCHROTH asm-
autocontrol harnessbelt is always:
1. after making sure that the transmission is in Park or Neutral
with the hand brake firmly engaged,
2. switch ignition on, but do not start engine,
3. buckle up,
4. only then, start the engine.
By following this procedure you will be able to prevent your car
from moving when you do not want it to while you are putting
on the harness belt.
