Diagnosis & Testing
Luggage Barrier
  1. Ignition OFF, disconnect the rear compartment partition position switch (S20).
  2.  
  3. Test for less than 3 ohms of resistance between the ground circuit terminal B and ground.
    1. If greater than the specified range, test the ground circuit for an open/high resistance.
    2.  

  4.  
  5. Ignition ON, install a 3A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool Luggage Barrier In Place parameter is Yes.
    1. If not the specified value, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the FTC module.
    2.  

  6.  
  7. If all circuits test normal, test or replace the rear compartment partition position switch.
  8.  

Switch
  1. Ignition OFF, disconnect the folding top open/close switch.
  2.  
  3. Test for less than 2 ohms of resistance between the ground circuit terminal B and ground.
    1. If greater than the specified range, test the ground circuit for an open/high resistance.
    2.  

  4.  
  5. Ignition ON, verify the scan tool Top Control Switch parameter is Idle.
    1. If the parameter is Opening, test the signal circuit terminal C for a short to ground.
    2.  
    3. If the parameter is Closing, test the signal circuit terminal A for a short to ground.
    4.  

  6.  
  7. Install a 3A fused jumper wire between the signal circuit terminal C and ground. Verify the scan tool Top Control Switch parameter is Opening.
    1. If the parameter is Idle, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the FTC module.
    2.  

  8.  
  9. Install a 3A fused jumper wire between the signal circuit terminal A and ground. Verify the scan tool Top Control Switch parameter is Closing.
    1. If the parameter is Idle, test the signal circuit for an open/high resistance. If the circuit tests normal, replace the FTC module.
    2.  

  10.  
  11. If all circuits test normal, test or replace the folding top open/close switch.

Removal & Installation
Motor
  1. Place the folding top in the fully closed position.
  2.  
  3. Open the rear compartment.
  4.  
  5. Disconnect the battery.
  6.  
  7. Place a protective covering over the rear compartment interior and the adjacent body panels.
  8.  
  9. Remove the right side compartment trim.
    NOTE
    Do Not remove the pump completely from the storage compartment.

  10.  
  11. Release the hydraulic pump pressure.
    NOTE
    When removing the motor it is NOT necessary to remove the hydraulic lines from the pump. The motor can be transfer from inside the storage compartment.

  12.  
  13. Use a clean shop towel to control any hydraulic fluid leakage.
  14.  
  15. Disconnect the electrical connector from the hydraulic pump.
  16.  
  17. Stand the pump and motor upright to gain access to the pump motor screws.
  18.  
  19. Remove the screws from the pump motor.
    WARNING
    Do Not let the pump propeller driver separate from the pump when pulling apart. If the pump propeller driver separates from the pump it is no longer serviceable and must be replaced.

  20.  
  21. Remove the motor from the pump assembly.
  22.  

To install:

  1. Install the pump propeller to the motor.
  2.  
  3. Stand the pump and motor upright to gain access to the motor screws.
  4.  
  5. Install the screws to the pump motor and tighten to 89 inch. lbs. (10 Nm).
    WARNING
    When reinstalling the pump motor propeller it must be in-line with the pump propeller driver.

  6.  
  7. Install the motor to the pump assembly.
  8.  
  9. Connect the electrical connectors to the hydraulic pump.
  10.  
  11. Install the nuts that attach the pump bracket to the floor pan. Tighten to 13 ft. lbs. (18 Nm).
  12.  
  13. Install the 2 nuts that attach the control module to the pump bracket.
  14.  
  15. Remove the protective covering from the rear compartment interior and the adjacent body panels.
  16.  
  17. Tighten the hydraulic pump bypass valve.
  18.  
  19. Connect the battery.
  20.  
  21. Inspect the hydraulic system for leaks and fluid level.
  22.  
  23. Install the side compartment trim.
