You can download the full list of DTC's in our download centre here https://www.jaguarforums.com/forum/g...r-index-50609/
The X-Type is the X400, there is a section "Jaguar Fault Codes" and the file is "400OBDII_2002MY"
The document is the official DTC list from the JTIS, which also gives a list of possible causes for each code.

i have all data and it says could be :
P1638:
CAN open circuit fault - INST to ECM
CAN short circuit fault
INST failure
ECM failure
what is CAN? what is INST? is ECM engine control module?
P1603:
battery disconnected while ignition is switched on
B+ power supply circuit: open circuit
TCM failure
is TCM transmission control module? what is B+?
