P1603: Transmission Control Module (TCM) EEPROM Failure C1145: Front right wheel speed sensor input circuit failure
The P1603 means that your TCM has probably failed. It may have a loose solder connection or the PROM chip may have come out of it's slot. EIther way the TM needs tobe removed from the car and repaired/replaced by a qualified repair person.
The C1145 is for the ABS and it may be related to the TCM failure. I am not that familiar with the Jaguar ABS system, but that code means the signal from the front right wheel is bad. May be the sensor or the "tone ring"...
