Hello John,

How to Reset the Computer on a 2004 Jaguar XJ8

Step 1

Start with the ignition key in the "O" -- ignition off -- position. Press and hold the rear fog lamp switch.

Step 2

Press the "Start" button -- as though trying to start the car -- without putting your foot on the brake; this will put the car into "Power Mode 6." Immediately release the fog lamp switch.

Step 3

Press and hold the computer display cycle switch, then press and hold the rear fog lamp switch again. Continue holding the two of them while the system resets.

Step 4

Look at the display. If the process has been successful, the message center will display "Resetting Service Mode" for 10 seconds. After that time, it will read "service Mode Reset."

Step 5

Release both switches and remove the key from the ignition.

Hi Aubrey .

Thanks for you info on rebooting the electronics.

My XJ8 does have an ignition key but does not have the start button you describe in your text. Therefore I cannot follow the process you have described.

Am I missing something.

Hi Leccey,

Sorry I am unable to find any info at present on that.

Can I check is it XJ or XK as on your profile?

Cheers,

Aubrey.
