which module won't communicate ? need a up scale scanner to communicate with all the modules on the vehicle. Do you know what C.A.N - controller area network is ? Serial data bus (network) All the modules on the vehicle share data on the network . U code's indicate a problem with the network .

If its a Shark then fault 8 : SHARK Power Module Fault
Check SHARK Connections and Wiring Replace the Power Module
if its a DX fault 8 : Over Voltage Fault
Check Battery voltage is below 32V Check Battery wiring and terminating is secure

yes. when one of the phase is out, the other two power module is usually overloaded and burnt. swap it.

You have a module problem:

Evaluate your batteries. 12v Single or 24 together.
Flash codes:
1. Stall Timeout, Joystic out of neutral
2. Battery Voltage too over 32VDC hi or too low under 17VDC
3. Left motor Fault
4. Right Motor Fault
5. Left Brake Motor fault
6. Right Brak Motor fault
7. Shark Control Module Faul
8. Power Module Faul
9.Shark Module Faul

1. Stall Timeout, Joystic out of neutral

Unfortunately it will be one of 2 things that is stopping your machine from powering up 1st--The control module is faulty -2nd-- Your pump is open circuit. Now the two reasons that the control module became faulty are --1-- It faulted internally. and --2---There is a faulty part on your machine that caused the control module to fault. My best guess it will be the diverter valve.They have a wax motor in them that always faults and causes the control module to fault as well.Has your machine got an Efficiency button?If it has then the faulty part that could have caused the fault will be the drain pump,as this model has a mechanical diverter inside the pump.Please reply with the answers to the questions and i can guide you throe any repair that needs to be done.

OK, there are 2 faults that cause your machine not to power up, and they are, 1/ your control module is faulty 2nd-- your pump is open circuit. does your machine have the efficiency button? there are 2 reasons that the control module faults 1st - the computer faults by itself or 2nd-- the control module faults because there is something faulty on you machine eg- the pump is shorted out, the water valves are faulty etc. hope this helps and please reply for further help if needed.

Hi Akortic,



Without knowing the full model number of your UPS I cannot go into specific details fully for you.. but a good test with any 'power module fault' is to re-seat the module and run a self test. This only applies if you have an extra/redundant power module to support the load. If the fault remains then you have a bad power module and you will need to replace it as soon as possible. This can all be done 'on-line' and you should not have any downtime... assuming there is a redundant power module in the UPS. This will clear the fault.

If you would like more information give me a call: 407.380.9200.

the wire with the fuse belongs to external light fetures (unit does not have. It was intended for future use for external ligts)

the two yellow lights endicate problme with batteries( too low) or the module controller.

1. Stall Timeout, Joystic out of neutral
2. Battery Voltage too over 32VDC hi or too low under 17VDC

Hi,
Error "E-30" means motor fault, there are 3 main causes,
1) motor brushes worn.
2) wiring between motor and module bad connection or broken, pull on the wires gently on the ends, also look under the cable ties for chaffing.
3) Power module blown, this is located at the front (above the door seal), remove lid, front console panel (careful you dont damage ribbon cable when removing) remove front module then you will see plastic clips holding the power module on, have a look at the track of the module.
