I have a 2008 XKR. I received a number of restricted performance (limp mode) warnings when I pushed the car a bit. OBD II gauge showed P2601 fault code. I replaced supercharger coolant pump with a Bosch 010 pump as advised on this forum, but the problem persists. Next step is to check the relay and wiring. Does anyone know where to find the relay for this pump? All other suggestions welcome.

 

From another forum: "Try relay R12B and fuse F24 15A in the power distribution box.".

 

Thanks.

See attached photo. I have found fuse F24 15A, but not relay R12B. The relays in this box run from R1 to R8 (R1, R2 & R6 are empty). Am I missing something?

 

I see you've replied to the original answer poster on the other forum. Hope you get it sorted out.
