DIAGNOSIS/TROUBLESHOOTING FOR FAULT CODE 5 - STEPS 1 TO 6

Work instruction			Display OK	If not OK
1	Check functioning of convertible top	Ignition on Completely open and close convertible top	Problem-free functioning until the convertible top is almost closed, it is then necessary to pull on the gripper to lock it completely Close convertible top, soak with water and allow to dry in closed position (at least 10 hours) ->End	Step 2
2	Preparatory work for step 3: Ignition on Connect Porsche System Tester II 9588 and call up the Input signals menu Select and call up the following 9 input signals: Closure locked Closure unlocked Convertible top Convertible-top compartment lid Side flap top right Side flap bottom right Side flap top left Side flap bottom left Latching hook		Step 3
3	Check switch positions when convertible top is closed	Close convertible top completely until it has reached its final position Check switch positions	The following switches indicate "closed": Closure locked Side flap bottom right Side flap bottom left The following switches indicate "open": Closure not unlocked Convertible top not raised Convertible-top compartment lid locked Side flap not top right Side flap not top left Latching hook actuated Step 4	If one or more switch postions are not as described above, the respective switch or wire is faulty Carry out test as described in fault code 1
4	Check switch positions when convertible top is open	Open convertible top completely until it has reached its final position Check switch positions	The following switches indicate "closed": Closure locked Convertible top raised Side flap top right Side flap top left Latching hook not actuated The following switches indicate "open": Closure not unlocked Convertible-top compartment lid locked Side flap not bottom right Side flap not bottom left Step 5	If one or more switch postions are not as described above, the respective switch or wire is faulty carry out test as described in fault code 1
5	Preparatory work for step 6: Ignition on Call up data logger in the Input signals menu in Porsche System Tester II 9588 Select and call up actual value Pot. 1 convertible top		Step 6
6	Check voltage characteristic from Pot.1 convertible top while opening and closing	Close convertible top completely until it has reached its final position and open it again observe the voltage characteristic in the process repeat the process if necessary	The voltage characteristic has a continuous path (similar to that illustrated in the figure below) and changes over the exact period of time in which the convertible top is moving in the rear area Step 7	The voltage characteristic no longer changes even though the convertible top is still moving in the rear area Carry out test as described in error code 1

NOTE:
