Removal & Installation
  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  
  3. Raise (close) the soft top to a position with the soft top cover raised and the fifth bow lowered (horizontal).
  4.  
  5. Fold forward the rear backrest.
  6.  
  7. Disconnect or remove the following:

    Cover over the hydraulic unit
     
    Hydraulic unit retaining bolts
     

  8.  
  9. Lift up the hydraulic unit. Check the oil level in the oil reservoir.
  10.  
  11. Lay out paper under the hydraulic unit to catch any oil spills.
  12.  
  13. Unplug the connectors.
  14.  
  15. Mark the hoses and remove the retaining bolts by the hose connections.
  16.  
  17. Remove the cable tie securing the hoses.
  18.  
  19. Remove hydraulic unit.
  20.  
  21. To install, reverse removal procedure.
  22.  
  23. Fill oil in the reservoir. Use specified oil.
  24.  
  25. Run the soft top up and down 5 times and check the function. Check to make sure that there are no oil leaks.
  26.  
  27. Check the oil level and top up if needed.
  28.  
  29. Run the soft top to closed position and lock it to the windscreen frame.
  30.  
  31. Connect the diagnostics tool, erase any diagnostic trouble codes.
  32.  

Diagnosis & Testing
  1. Measure voltage to check for open circuits by performing the following:

    Engage the load
     
    Set the multi-meter to voltage measurement and connect its minus cable to a good grounding point
     
    Connect the voltmeter positive cable to the point where the voltage is to be tested
     
    On the output side of a switch/control module, it is best to start there and then gradually move out towards the load
     
    The break point in the circuit has been passed when the voltage disappears
     
    On the input side of a switch/control module/consumer, it is best to start at the closest point to the power source (often the fuse) and then gradually move towards the switch/control module/consumer
     
    The break point in the circuit has been passed when the voltage disappears
     

  2.  
  3. Measure resistance to check for open circuits by performing the following:

    Make sure the component or lead being tested is not carrying a current (e.g. by removing the associated fuse)
     
    Set the multi-meter to resistance measurement and connect it across the component/lead being tested
     
    Move the wiring harness in question while observing the ohmmeter
     
    The resistance of the wiring harness should normally be less than 1 ohm. A specified value applies to components
     

  4.  
  5. Check for short circuits to ground by performing the following:

    Make sure the lead being tested is not carrying a current (e.g. by removing the associated fuse) and that any load has been disengaged
     
    Set the multi-meter to resistance measurement
     
    Connect one test cable to a good ground and the other to the point to be tested
     
    Carefully move the wiring harness and make sure the multi-meter shows infinite resistance (OL) the whole time
     

  6.  
  7. Check components connectivity and functionality. Replace components as necessary.
