P1651 (Fan Control Relay) and P1652 (Power train Induced Chassis Pitch Output Circuit)

Fan control relay may be according to some research a broken wire, you may have to do a continuity test down the loom, the other is something i have never come across and i am struggling to find any info on line, you may have to ask a dealer about that one.
