can you help on this error code C21A909 for the Radar Module -Front center (MRR)???
It appeared after a front window replacement - and since caused issues (=fully down) of front collission assitant, lane assist, traffic light status indication
DTC report after my recent FCM calibration attached: ECU resets of FCM+Hydra+MRR, finished with a deep sleep . Software versions as well (MRR doesn't show up there)
Is it rather
a) a calibration issue?
or
b) a connection issue of wires/plugs (e.g. water in a plug; or simply plug was disconnected in a repair, but not properly reconnected)?
or
c) even a module hardware failure?
or maybe something completely different?
The interesting thing is that after calibrating the FCM with Freesker tool, the front collission assistant (including braking in close situtations), the lane assist, the traffic light status indicator started working again - so I was wondering how a front collission assistant incl braking could work without the Front center radar module, i.e. I think this module does work actually.
Nevertheless, these warning symbols keep on shining, and the error code C21A909 still remains :-(
Any hint and recommendation what to do next?
Thank you so much in advance!
My FO keeps showing the same faults again and again after a reset: CMRR RL and CMRR RR, specifically MRR Online Calibration Error (DTC C228E00).
Unfortunately, I can’t calibrate the CMRR/CMRR because this function is not enabled/activated in my system.
In addition, while driving, the yellow blind-spot warning indicators in the driver display keep lighting up repeatedly.
This is very distracting and especially bothersome at night during driving.
Is there a way to use Freesker offline? Many Fisker owners keep their vehicles in garages or underground parking lots with no internet signal, so there’s no way to clear errors or perform a reset there.
An app for Apple iOS users would also be of interest. Thank you very much for your reply.
Was able to deleted missing FOB#1 add a new FOB#1 to the car but none of the buttons will work. the NFC of the FOB works fine. Tried new Battery in FOB verified it has correct PKC seen 110A and confirm the buttons working using RF Connect Scanner app on phone. Tried Un-Pairing and Re-pairing. Tried PKC reset- No Luck. Still sees NFC but no buttons work--- Any Suggestions?
