Park Assistant PO2

Introduction

General Instructions/Safety Instructions

The following points must be observed during vehicle diagnosis:
- The Park Assistant signals readiness with a short signal tone, provided that the ignition is switched on and the reverse gear is engaged
- After the battery is connected, volatile memories must be reprogrammed. In the case of radio coding and tuning, the customer must be informed of decoding and the deleted tuner memory.
- After troubleshooting or repairs, erase the fault memory with the Porsche System Tester 2 and carry out a test drive.
- After the test drive, read out the fault memory with Porsche System Tester 2 again.

CAUTION.
Danger of damage due to improper handling of the battery and the control module connectors.
- Never disconnect battery with engine running.
- Never start engine without securely connected battery.
- Never pull off or push on plug connections of the control modules or other electronic components when the ignition is switched on.

WARNING.
Danger of injury and damage to vehicle when the vehicle is rolling backwards.
- Reverse gear must be engaged and the ignition must be switched on; otherwise the Park Assistant System is deactivated.

WARNING.
Danger of injury and damage to vehicle when the system limits are reached. The system does not tree the driver from his/her responsibility to be careful.
- Short obstacles such as a person lying down cannot be detected.
- The reflecting behaviour of the system can be impaired by sound-absorbent obstacles such as powder snow or sound-reflecting obstacles such as glass surfaces.
- Very thin obstacles and obstacles with no reflecting surfaces cannot be detected.


General Information on the Fault Memory

Fault Code Setting Conditions

Fault codes can be set in several circumstances, e.g.:
- Power failure
- Plug connections disconnected

In these circumstances, no fault is present in the system and the fault memory must be erased.


Fault Memory Info Key [F8]

In order to be able to assess the fault exactly, the fault memory Info key [F8] must be pressed. This information should be saved using the Save key [F8] and printed out. If a fault code is stored with "not present" status and no other problems are present, then the fault memory must be erased.


Open circuit - short to ground / voltage short / coding / vehicle parameters

Open circuit or short to ground: There is (present) or was (not present) a short-circuit to ground or an open circuit in the circuit to the control module terminal.

Voltage short: There is (present) or was (not present) a short circuit to voltage.

Coding/vehicle parameters: Incorrect vehicle coding or coding not carried out.
