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.
This is a source reference. Confirm exact model applicability in the original material.
