Reset check engine light on 2003 s type Jaguar

SOURCE: check engine light code p1603

When I went outside to start my Jaguar X-Type it was cold outside. I was in a hurry and didn't let the car warm up properly. It jumped a bit then the check engine light came on along with a message that said No cruise control. The no cruise light came off but my check engine light is still on. Any suggestions as to what it may be?

you can reset the engine warning light by taking the earth lead off the battery and connecting it to the positive lead, then switch on the ignition,. Reconnect the earth lead to the battery and the light will have been reset. What you are doing is discharging the diagnostic chip to earth, which is exactly what the jaguar main dealer equipment does.This works on all cars.
PLEASE NOTE, make sure you disconnect the earth lead from the battery .

Rent a scanner, read out any code(s), and pursue to repairs. It may be as simple as bad spark plugs and wiring, or worse, fuel problems from the injectors back to the fuel tank. A worn O2 sensor can cause improper fuel/air problems.
