Fehlercodes C5

[Thomas V]

hast Du überhaupt Reifendrucksensoren bei Deiner C5 verbaut?
wenn ja, einfach mal neu anlernen.....

nebenbei: im 2004er Service Manual finde ich diesen Fehlercode gar nicht


okay....

für 2002er habe ich folgendes gefunden:

A newly replaced RCDLR will set DTC C2121 upon the first ignition ON cycle. If this DTC is set, refer to Tire Pressure Sensor Learn .
Loss of, or low system battery voltage will cause all of the sensor Id codes to be erased from the RCDLRs memory and set DTC C2120. If this DTC is set, or this condition is suspected, refer to Tire Pressure Sensor Learn .
If the vehicle is stationary for more than 15 minutes after being driven the sensors will go into stationary mode. Always test drive the vehicle above 32 km/h (20 mph) to ensure the sensors are in drive mode before viewing tire pressures on the DIC.
If there is an open in the serial data circuit to the receiver, the DIC will display dashes for all tire pressures and the SERVICE TPM SYSTEM message.
Occasionally sensor transmission will not be received by the RCDLR due to vehicle level RF interference.


also wie oben schon geschrieben: probiere mal mit Anlernen der Sensoren, ist zunächst das einfachste.
