Seats - Diagnosis: Other Porsche Boxster 986 рестайлинг

System readiness

The system allows the position to be changed if at least one of the following requirements is fulfilled

1. Term. 15 is switched on or
2. The driver's door is opened

Operational readiness is maintained for an after-running time of 60 s after the key has been removed or the door has been closed. If the position is changed during the after-running time, then the after-running time is started again. If the position is not changed during the after-running time, then the system switches to inactive state, thus reducing power consumption.

Information

Term. 15 must be switched on for communication with the PST 2.

System components

The system consists of the following components

1. Lumbar support
2. Motor for lumbar support (lumbar pump)
3. Switch for seat adjustment
4. Electric motor for seat adjustment
5. Electric motor for front height adjustment
6. Electric motor for rear height adjustment
7. Electric motor for backrest adjustment
8. Control module for memory seat adjustment
9. Switch for memory seat adjustment
10. Switch for rearview mirrors (door mirrors)
11. Changeover switch for rearview mirrors (door mirrors)
12. Right and left rearview mirrors (door mirrors)

The system enables the following system components to be adjusted individually

1. Front seat height
2. Rear seat height
3. Backrest angle
4. Left rearview mirror
5. Right rearview mirror
6. Lumbar support
7. Fore-and-aft adjustment

Storing the positions

1. Adjust the rearview mirrors, seat height, backrest angle and lumbar support to the desired positions.
2. Hold down switch M and push one of the switches for memory seat adjustment (1, 2 or 3) at the same time.

The positions are now stored under the number selected.

The following components are monitored by the system

1. Lumbar pressure sensor (regulating switch)
2. Potentiometer voltage of both rearview mirrors
3. Hall-effect sensor for backrest adjustment
4. Hall-effect sensor for fore-and-aft adjustment
5. Hall-effect sensor for height adjustment
6. Functioning of the control module (EPROM, A/D converter, main relay)
7. Switch for memory seat adjustment and switch for seat adjustment

When the switch for memory seat adjustment or the switch for seat adjustment are actuated, the faulty component is stored in the fault memory. In this case the word present also appears on the screen, for example

"Open circuit present in Hall-effect sensor for fore-and-aft adjustment"

If the cause of the fault is eliminated, then the switch for memory seat adjustment or the switch for seat adjustment must be actuated again. If the cause of the fault has really been eliminated, the text in the fault memory changes from present to not present .

Note. The fault memory must always be read out and any faults which may have been stored must always be deleted after diagnosis.

Tools

The following equipment is required for troubleshooting

Scheme 15

Scheme 16

1. Porsche System Tester 2
2. Commercially available digital multimeter

Scheme 17

Function of individual components

1. Parking aid When reverse gear is engaged, the corresponding rearview mirror (right-hand drive or left-hand drive according to coding) is lowered by the angle stored. Manual adjustment of the seat motors is carried out parallel to the lowering of the rearview mirror. Automatic adjustment interrupts the lowering procedure. If reverse gear is still engaged after automatic adjustment is complete, the rearview mirror is lowered again.
2. Rearview mirrors Manual adjustment of both rearview mirrors is carried out with the switches for rearview mirrors or changeover switch for rearview mirrors. When the desired positions have been set and stored by means of the switches for memory seat adjustment , automatic adjustment of the rearview mirrors is carried out by actuating the corresponding switch (1, 2 or 3).
3. Support with gear unit The support with gear unit consists of the following components: Two electric motors with a potentiometer Gear unit
4. Front seat The following are the possibilities for adjusting the front seat: Backrest Front height Rear height Longitudinal direction Upper lumbar Lower lumbar When the desired positions have been found and stored by means of the switches for memory seat adjustment , they can be called up at the push of a button when required.
5. Control module The control module is fastened under the front seat (driver's side) with two screws. There is a total of 10 connection points on the control module.
6. Switches for memory seat adjustment These switches [M, 1, 2, 3] can be used to store or call up the optimum positions once they have been found. The systems enables adjustment values for three persons to be stored.

Lumbar support

The lumbar support consists of two cushions which are inflated by means of a motor for lumbar support. The cushions are inflated or deflated to the required pressure one after the other beginning with the upper cushion. The pressure in the cushions is measured using a pressure sensor (regulating switch). The pressure sensor is located at the same height as the headrest and is integrated into the lumbar adjustment. Automatic adjustment of the lumbar support is carried out by actuating the switch for memory seat adjustment. The motor for lumbar adjustment is (Scheme 18)together with both lumbar cushions. Automatic adjustment of the lumbar support is divided into two phases.

Scheme 18

Scheme 19

1. If the seat motors have not yet reached their required position, adjustment of the lumbar support is interrupted by releasing the switch for memory seat adjustment.
2. If the seat motors have reached their required position, adjustment of the lumbar support is completed after the switch for memory seat adjustment is released.
