The following components are monitored at cyclical intervals with the ignition switched on and reverse gear engaged.
- Control module supply voltage
- Sensor supply voltage
- Functioning of all sensors
- Functioning of control module (transmission and reception pulses, EEPROM)
NOTE:
External weather conditions such as ice, snow or dirt can impair the functioning of the sensors and result in an error.
The four sensors are connected to the control module by a wiring harness installed in the rear spoiler. The rear spoiler must be removed to replace the sensors or take measurements.
