Parking Assistant Porsche Boxster S 986 рестайлинг

DESCRIPTION & OPERATION

Parking assistant system is automatically activated when reverse gear is engaged. System uses 4 ultrasonic sensors evenly spaced along rear bumper centerline to detect objects at varying distances behind vehicle. Outer sensors (2) have a range of 60 cm approximately, inner sensors (2) have a range of 150 cm approximately.

Note. Sensors are NOT activated if vehicle rolls backward without reverse gear engaged.

System emits a single short tone when reverse gear is engaged to confirm system operation. Detected objects are indicated by intermittent tones. When object is less than 1 foot away from vehicle, system emits a continuous tone. Tone will stop if vehicle motion is stopped, and will sound again if motion resumes. Objects very low to the ground (i.e., below bottom bumper contour) may not be detected by sensors. Parking sensors cannot detect sound-absorbing objects (i.e., powder snow), sound-reflective objects (i.e., glass or flat painted surfaces) or very thin objects. Other ultrasound sources like pneumatic brakes of other vehicles or jackhammers may interfere with sensors.

Indication of system fault is through warning tones. If a system fault is present, the single tone emitted after reverse gear is engaged will be followed by a continuous tone of much lower pitch. Dirty or icy sensors will also indicate a fault by emitting a continuous tone of the same pitch as the single activation tone. For cleaning instructions, see CLEANING ULTRASONIC SENSORS under ON-VEHICLE SERVICE.

CLEANING ULTRASONIC SENSORS

Sensors can be de-iced and cleaned using a steam-jet cleaner. Always maintain a sufficient distance to prevent damaging sensors and paint.

MODIFYING CODING

1. Connect Porsche System Tester 2 to diagnostic socket. (Scheme 2)
2. Turn on System Tester 2. Allow about 1 minute for Tester to come on-line.
3. Turn ignition on.
4. Select vehicle type and start diagnosis by pressing the "2.14" button. Computer will list all control modules on vehicle and will list non-existent (example: Tiptronic module on a vehicle with manual transmission) in gray.
5. Select "Park Assistant" control module.
6. Select "Modify Coding" Menu.
7. Select vehicle type and press F8 to confirm.

PREPARING PORSCHE SYSTEM TESTER 2

1. Connect Porsche System Tester 2 to diagnostic socket. (Scheme 2)
2. Turn on System Tester 2. Allow about 1 minute for Tester to come on-line.
3. Turn ignition on.
4. Select vehicle type and start diagnosis by pressing the "2.14" button. Computer will list all control modules on vehicle and will list non-existent (example: Tiptronic module on a vehicle with manual transmission) in gray.

Accessing Fault Memory

1. Connect Porsche System Tester 2 to diagnostic socket (located under left side of dashboard).
2. Switch on ignition and System Tester. Allow about 1 minute for Tester to come on-line.
3. Press F8 key to retrieve fault memory. Save with F4 key.

DIAGNOSTIC TESTS

DIAGNOSTIC TROUBLE CODES (DTC) LIST

Possible Causes

1. Short circuit to B+ voltage in supply lead to outside right sensor.
2. Short circuit to ground in supply lead to outside right sensor.
3. Open circuit in supply lead to outside right sensor.
4. Faulty outside right sensor.

Elimination

Clear fault memory, disengage reverse gear and turn ignition OFF. Turn ignition ON. Engage reverse gear and read out fault memory. If fault appears again, check electrical plug on sensor for open circuit.

If no open circuit, check for continuity between sensor connector, between pin 1 and pin 4. Check continuity between sensor connector, pin 1 and pin 2 also. In both cases, no continuity should exist.

If no faulty wiring is found, replace sensor.

1. Low vehicle voltage.
2. Faulty generator.

Check voltage from battery and generator and replace any faulty components. Using Porsche System Tester 2, select "Actual values" menu Select "Control module supply voltage" and "Sensor supply voltage" menus and check values with reverse gear engaged and engine running. Supply to control module should be approximately 12 volts and supply to sensor(s) should be approximately 8 volts.

After checking actual values, clear fault memory, disengage reverse gear and turn ignition OFF. Turn ignition ON again, engage reverse gear and read out fault memory.
