Disconnected the battery of my 2004 XK8 to work on passenger seat module. On reconnecting the battery, my radio is dead! Worked great before so I checked fuses and all seem to be OK. Help please!

 

Try inputting the PIN code, even tho it's apparently not asking for one.

 

Jetjock, Look in your paper work for a radio code. A four digit number, If you have all the paper work with the car it will be on a card, I have found them written up in the corner of a page that shows how the radio works. A Jag dealer can give you the number if you go there and show proof of ownership and the VIN number.

Thnx for the suggestions but unfortunately did not receive original paperwork fromthis US car when imported to Canada. Radio seems dead so not sure if entering a code would work. Looks like I should try the battery reflash procedure where the ground wire is connected to the positive terminal for 10 secs than reconnected. Sort of like a reboot!

 

That's a hard reset. A reflash would involve reinstalling the software.

 

Again many thnx for help. Will try a hard reset and hope!

 

Well, . . . there are only 10,000 combinations in a 4 digit code.

Just kidding. Hope you get it fixed.

 

Well looks like this radio wants a code. Will try the local dealer nest week and see if he can help. The car was in for service recently and itlooks like the battery terminals were cleaned and coated so someone must have reset the radio code. The search begins!

 

Do you mean DEAD as in no signs of life or is it powering up and displaying the word CODE?

Coded radios are very rare but not unknown in US market models.

No signs of life. No audio and the display is blank. Checked all the fuses in the fascia, trunk and under the hood and they are all good.

 

Then a code is not not the issue. The display will say 'code' if you need to enter one.

It is easy to miss a hairline break in a fuse, especially if you are looking at all of them. I suggest replacing fuse F9 (10 Amps) and F12 (5 Amps) on the passenger side of the dashboard, or at least checking them with a multimeter.

 

Thanks for the tip. I have checked all with an Ohmeter and they all passed but I'll try relacing the two you suggested. It sure looks like a fuse to me too. I guess there isn't an inline fuse for the radio?

 

There would be only if your car has an aftermarket radio installed.

 

Well, I replaced the F9 and F12 fuses in the passenger facia panel and no change.

 

If you gave a DMM, set it to volts and see if you have about 12 volts at the exposed metal on the top of each side of both those fuses, with the ignition on.

 

Success sir! Not really sure what happened but when checked F12, it showed no voltage. Re-installed and bang the radio lit up! Will clean all the connectors with contact cleaner but dirty contacts looks like the problem. Thank you very much for your help and patience.
