Preparation For Test - Section 22

Preliminary work:
Diagnosis - Diagnostic Trouble Code (DTC) Memory, Diagnostic Trouble Code (DTC) Memory - Section 12

- Battery voltage 11-14 V.
- Fuses OK.
- To avoid damage to the control modules, connectors should only be disconnected or connected with "Terminal 15R: OFF".
- Connect HHT as described in section 0. Connection and Use of Test Equipment - Section 0

The power window and roll bar systems are also activated when the soft top is operated. The complete diagnosis of these systems can be found in the following:
Convenience Feature (CF) (Inc. Power Windows/Sliding Roof), Convenience Feature (CF) (Inc. Power Windows/Sliding Roof)
Roll Bar Crash Deployment, Roll Bar Crash Deployment
The soft top must never be unlocked or locked while driving and the soft top can only be operated when the vehicle is stationary.

To prevent a collision between the rear cover and the soft top compartment cover, the soft top can only be opened or closed automatically when the rear cover is closed.

To prevent damage to the soft top or items in the trunk:
- The soft top can only be opened or closed automatically when the trunk luggage cover is attached.
- Do not open or close the soft top when the soft top material is frozen or at temperatures below -15 °C.
- Only open the soft top when it is clean.

Before opening the soft top with the power soft top switch (S84), the unlocking lever must be turned clockwise and the soft top raised slightly; then turn back and fold up the unlocking lever.

Once the soft top has closed automatically the unlocking lever must be turned clockwise and the soft top pulled onto the window frame; then turn the unlocking lever counterclockwise and fold up.

The following is to be observed after test and maintenance work:
If malfunctions occur when operating the soft top and the soft top remains in an intermediate position, the soft top is first to be moved manually to an end position (completely closed or completely opened). The roll bar (RB) control module (power soft top) (N52) then recognizes the exact position of the soft top. After this a function check is to be carried out.

WARNING!
Danger of injury!
Prior to performing any testing, refer to the Hydraulic Test Program for important safety warnings and precautions. Hydraulic Test Program

Notes on emergency soft top operation
The soft top can be closed manually in the event of a defect in the soft top system or vehicle electrical system. If possible, this should be done carefully by two people.

Preparations:
The valve screw (a) on the hydraulic unit must first be opened before the emergency operation can be performed. As a result, the valve opens and the hydraulic cylinders (open/close soft top) are switched to return on the rod side. Only after this is it possible to move the soft top linkage manually.

The valve screw (a), is to be closed again after emergency operation. Otherwise, the soft top could be moved manually Out of the soft top compartment by unauthorized persons. In addition, objects in the trunk would be fully accessible.

NOTE: The exact procedure for emergency soft top operation can be found in the Owner's Manual.

Component Identification:

Working with test cable and socket box
For test work on the soft top or rear side windows when using the 55-pin test cable, it is absolutely essential to observe the following:
Before connecting the test cable, if possible open the rear side windows with the power soft top switch (S84).

Only activate the rear power windows briefly when the test cable is connected so that the test cable is never overloaded due to the high current draw of the power window motors.
