Checks
1. Check whether the battery plug
is correctly and fully connected
to the steering unit.
2.
Check whether the batteries are
correctly connected to each
other.
3.
Check the charge of the
batteries.
4.
Check the fuses of the steering
unit and the batteries, whether
they are defective, have been
removed, or are burnt out.
1.
Faulty programming (incorrect
interpretation (DX, S, Plus)).
2.
internal faults (replace the
steering unit).
ATTENTION: Should the steering
unit be replaced, a new error code
might be indicated afterwards,
because a complete fault
diagnosis could not have been
carried out.
Check the status of the attached
module.
1.
Check whether the plugs of
both motors/parking brakes
are properly inserted.
1.
Check the contacts of both
motors/parking brakes for
corrosion or damage.
2.
Check both motors. Unplug the
motors/parking brakes and
measure the connection with an
Ohm meter. If the resistance is
more than 1 Ohm or less than
100 milliOhms, then the motor is
defecktive.
3.
Check the resistance between
the motor and its housing by
means of an Ohm meter.
Measure every contact between
the motor and its housing. If the
resistance is less than 1
MegOhm, the motor is defective.
NOTE: If one motor is faulty, the
other one could also be defetive.
