This response code shall be used if internal conditions within the node (ECU)
prevent the clearing of DTC related information stored in the node (ECU)

RCR-RP
This response code can be sent if the ECU is not capable of processing
additional diagnostic requests while the DTC clear is taking place. In this case,
the final positive response shall be sent upon completion of the DTC clear or
once the ECU can accept further diagnostic requests (prior to the finishing of the
DTC clear). The ECU shall also reset and temporarily disable the P3
C 
timer (if
the P3
C 
timer is active) for the duration that the ECU is performing the DTC
clear and is not capable of receiving diagnostic requests.
