(Navigation)

Navigation - introduction
The manual contains the diagnosis for the following system:
PCM2 navigation

General instructions/safety instructions
The following points must be observed during vehicle diagnosis:
- 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 the battery has been connected, the instructions in the assembly must be observed.
- Deactivate the "automatic traffic announcement" before beginning the diagnosis on the PCM2. If this is not done, the system will crash (applies only to software version < 03).
- When working on the optical waveguide, please observe the instructions in assembly Optical waveguide - MOST bus.
- After troubleshooting or repairs, erase the fault memory with the 9588 Porsche System Tester II and carry out a test drive.
- After the test drive, read out the fault memory with the 9588 Porsche System Tester II again.

DANGER:
Danger of injury through triggering of driver's airbag.
- 9588 Never hang the Porsche System Tester II over the steering wheel.

CAUTION:
Danger of damage due to improper handling of the battery and the control unit connectors.
- Never disconnect battery with engine running.
- Never start engine unless battery is connected securely.
- Never pull off or push on plug connections for the control modules or other electronic components when the ignition is switched on.

General information on the fault memory

Fault code setting conditions
Fault codes can be set in several circumstances, e.g.:
- battery disconnected
- plug connections disconnected
- power failure

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 [F4] 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.

Fault type - Frequency counter/Temperature/Voltage; Speed/Time of occurrence

Fault type The display shows which fault type has occurred:
- No GPS info
- Gyroscope faulty

Frequency counter When a fault first occurs, a fault entry is made in the fault memory and the counter is simultaneously set to 50. If a fault is present, the counter is incremented by 1 for each "ignition on". The maximum count is 100. The counter is decremented if the fault is no longer present. The fault memory is erased automatically when the counter reaches 0.

First occurrence (month, day) The date (month and day) on which the fault was first detected is displayed.

Temperature - first occurrence The value indicates the temperature (temperature sensor in the gateway) at the time the fault occurred. The temperature of the fibre optic transmitter is monitored: max 85 °C.

Speed - first occurrence The value indicates the vehicle speed at the time the fault occurred.

Supply voltage - first occurrence The value indicates the voltage at the time the fault occurred.

Hourmeter - first occurrence The value indicates the operating hours at the time the fault first occurred.

Last occurrence (month, day) The date (month and day) on which the fault was last detected is displayed.

Temperature - last occurrence The value indicates the temperature (temperature sensor in the gateway) at the time the fault was last detected. The temperature of the fibre optic transmitter (FOT) is monitored: max 85 °C.

Supply voltage - last occurrence The value indicates the voltage at the time the fault last occurred.

Hourmeter - last occurrence The value indicates the operating hours at the time the fault was last detected.

Vehicle hand-over
The PCM2 is converted to delivery mode (low-current mode) in production. As known from other systems (alarm system, instrument cluster, roll-over bar), the PCM2 must be activated with the 9588 Porsche System Tester II.

1. Connect and start the 9588 Porsche System Tester II and switch on the ignition.
2. Select 'Special functions' in the Vehicle type menu and confirm with the [>>] key.
3. Select 'Vehicle hand-over' in the function selection Special function and confirm with the [>>] key.
4. Follow the instructions of the 9588 Porsche System Tester II.

Control module replacement - PCM2
The PCM2 is provided in 'active production mode' in new vehicles and as a spare part. Each time the vehicle is started, the model range code that is stored is compared with the code in the instrument cluster. If no match is found, the device switches off after 30 seconds and the 'PROTECTED' message appears in the display. The device is not operational.

If a match is found, the device is operational. No further checks are made while the device is connected to the vehicle electrical system.

Coding PCM2
1. Connect and start the 9588 Porsche System Tester II switch on the ignition.
2. Select 'Boxster (986)' in the Vehicle type menu and confirm with the [>>] key.
3. Select 'PCM' in the control modules selection and confirm with the [>>] key.
4. Select 'Navigation' in the PCM2 function selection and confirm with the [>>] key.
5. Select 'Coding' in the Navigation function selection and confirm with the [>>] key.
6. Select 'PCM2 code' in the Navigation coding function selection and confirm with the [>>] key.
7. Take the PCM2 code from 'IPAS', enter it in the form and code with the [F8] key.

Country-specific tuner settings

The following selection is available:
- Europe
