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.
The following components are subject to cyclical monitoring when the ignition is on and the shift lever is in reverse gear:
- Control module supply voltage
- Sensor supply voltage
- Function of all sensors
- Function of control module (transmission and reception pulses, EEPROM)
NOTE:
External environmental conditions such as ice, snow or dirt can also adversely affect the function of the sensors and lead to a fault being stored.
The four sensors are connected to the control module via a wiring harness incorporated in the rear spoiler. To replace the sensors or to perform tests, the rear spoiler must be removed.
