Fault memory Info key "F8"
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.
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
| Supply voltage fault type | The display shows which fault type has occurred:
|
| Frequency counter | When a fault first occurs, a fault entry with the status present is set in the fault memory and the counter is simultaneously set to 50. If a fault is present, the counter is incremented by one whenever the system is booted. The maximum count is 255. The counter is decremented if the status fault no longer present is entered and the fault does not occur again when the system is booted. The entry in the fault memory is erased automatically when the counter reaches 0. If the error occurs again when the counter is between 1 and 49, the counter is reset to 50. |
| Temperature: | 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. |
| Voltage | The value indicates the voltage at the time the fault occurred. |
| Vehicle speed: | The value indicates the vehicle speed at the time the fault occurred. |
