Fault Information

Fault Code Description
The fault is detected when following fault causes occur: Wheel detection not possibleRadio link interference caused by external influenceWheel module from incompatible manufacturerWrong-generation wheel module The individual fault causes are stored in the corresponding types of fault. Fault entry condition for corresponding type of fault: Types of fault: wheel detection not possible/too many wheel electronics: RDC control unit cannot learn the wheel electronics in the vehicle within 9 minutes (EU) or 12 minutes (US) of driving time.Type of fault: external influence: The RDC control unit determined a fault in the radio link for at least 10 minutes. The display is cancelled after terminal change.The type of fault is an incorrect wheel electronics generation: At minimum one of the four wheel electronics feature an incorrect generationIncompatible wheel module manufacturer fault: at least one of the four wheel modules is from an incompatible manufacturer.

Service Plan
Possible fault causes for individual types of fault: Type of fault, wheel recognition not possible: Radio interference on vehicle (e.g. worn carbon brushes in alternator)Wrong or no wheel electronics installed Type of fault, wheel recognition, too many wheel electronics: Remove additional wheel electronics units from the vehicle. Type of fault, radio link interference caused by external influence: Check whether fault is caused by other radio systems in the vehicle (wireless headphones, baby-phone)If this fault also occurs in other locations with no other radio systems in the vehicle, perform a reset of the following component according to the test module (ABL): RDC control unit Wrong-generation wheel module fault: Carry out pressure coding to locate the wrong-generation wheel module. Incompatible wheel module manufacturer fault: Carry out pressure coding to locate the wheel module from the incompatible manufacturer.

Service Plan

Possible fault causes for individual types of fault:

Type of fault, wheel recognition not possible:
Radio interference on vehicle (e.g. worn carbon brushes in alternator)Wrong or no wheel electronics installed

Type of fault, wheel recognition, too many wheel electronics:
Remove additional wheel electronics units from the vehicle.

Type of fault, radio link interference caused by external influence:
Check whether fault is caused by other radio systems in the vehicle (wireless headphones, baby-phone)If this fault also occurs in other locations with no other radio systems in the vehicle, perform a reset of the following component according to the test module (ABL): RDC control unit

Wrong-generation wheel module fault:
Carry out pressure coding to locate the wrong-generation wheel module.

Incompatible wheel module manufacturer fault:
Carry out pressure coding to locate the wheel module from the incompatible manufacturer.
