Left motor (or its
connection) is defective.
1. Check whether the plugs of both motors have been inserted properly.
2. Check the plug contacts of both motors for corrosion or damage.
3. Check both motors. Unplug the motors and measure the plug
connection with an Ohm meter. If you obtain readings of more than 1
Ohm or less than 100 milliOhms, the motor is defective.
4. Check the voltage difference between the motor and its housing.
Measure every contact between the motor and its housing by means
of an Ohm meter. If the resistance is less than 1 MegOhm, the motor
is defective.
5. Check the condition and function of the carbon rods of both motors.
N.B: If a fault is indicated in one motor, the other one could also be
defective.
4
Right motor (or its
connection) is defective
As described above.

5
Left parking brake (or its
connection) is defective
1. Check whether the plugs of the motors have been inserted.
2. Check the plugs for corrosion or damage.
3. Check the parking brakes. Measure the resistance of the
connections by means of an Ohm meter. If the resistance is larger
than 100 Ohms or less than 20 Ohms, the parking brake is probably
defective.
6
Right parking brake (or its
connection) is defective
As described above.
7
Shark control is defective
1. Unplug both motors. Switch the steering off and then on again, while
leaving the joystick in the neutral position. If this flashing sequence
appears again, the steering is defective.
2. Unplug both motors. Again switch the steering off and on while
leaving the joystick in the neutral position. Then briefly push the
joystick in any arbitrary direction. If the steering relay then clicks
twice and a fault is indicated in the left motor, the steering is in order.
If any other fault is indicated and the steering relay does not click
twice, the steering is defective.
3. Check the motors as described above in 3. and 4.
N.B: If a fault is shown in one motor while driving, it could be
indicated as a steering fault.
8
Shark – PM defective
1. Check the cables and plugs for corrosion and damage.
2. Check the BUS connecting cable (resistance).
3. Replace the PM.
9
Shark communication
error
1. Check the cables and plugs for corrosion and damage.
2. Check the BUS connecting cable (resistance).
3. Replace the PM.
4. Replace the shark control.
10
Unknown error
1. Check the cables and plugs for corrosion and damage.
2. Check the BUS connecting cable (resistance).
3. See the manufacturer.
11
Incompatible steering unit 1. Incorrectly programmed and incompatible steering (depending on
system).
2. Check whether the programming of the PM and steering unit agree
with each other.
