System description: Diagnosis
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.
