Default Restricted Performance with U0426 and P2601

My 2006 XJR developed Restricted Performance. Actron Code Reader indicated U0426 Invalid Data Received From Vehicle Immobilizer Module and P2601, I have not been able to find a definition for P2601. I cleared the codes, but when driving a short while later, got the codes again. Miles are 160,211

Any thoughts?

It seems that it's a problem with your intercooler pump.
