It is for sure that there are issues in the ABS section and must be checked immediately. So check all the FOUR wheels, check the HUBS, check the ABS sesors and wiring from them., A fault here can cause this error and is most common.
Next check on the working of the ABS main module which might need a check at the service center.
C0550 is the code for the ABS module. It is on the frame under the vehicle around the drivers door area. It is a module with all the brake lines coming from it. Reset the trouble codes and see if the problem returns. If it does, the module is not serviceable and will need to be replaced.
