Default No back up lights or Rear Fog

just checked fuses and nothing looks blown in the boot fuse panel. Anything else to check or is this the dreaded SCLM? My other Jag the brake lights went and I rigged, but this one everything was tip top and now this.....any suggestions appreciated guys!

Looks like 2 possibilities:
I know you checked all the fuses, but try replacing fuse number 1 (10 amp fuse) in the trunk (luggage) fusebox.

Luggage fusebox - fuses table:




The relays in the trunk fusebox diagram has shows "heated rear window" R2 also "tail and number plate lamps" R3.



If that does fix it, then it probably is the SCLM module (Rear Fog Lamp Supply BT1-4 pin -- wire is orange with yellow stripe) and (Reverse Lamp Supply BT1-5 pin -- wire is orange with green stripe).

I did try the fuse number 1 but did not look at the relays. Will look tonight.

On the R/H hinge, remove the plastic cover and examine the wire harness. It is very common for the wires to break over time. Think of it like bending a paper clip back and forth over and over, the wire hardens and eventually breaks.
