One is called FREYA the otherRACOON. As information and repair ac

9、tivity aboutRACOON is not defined yet, this part is not included in thisService Manual.Notice that both Mechanisms can not be interchanged, soRACOON has to be replaced by RACOON, FREYA byFREYA. As both parts can only be repaired with the help ofCDR-ComPair, the ComPair tool will contain the instruct
