If I do a hard reset for 30 seconds, probably don't need the radio code? Many different answers on line (picked the Jag Forum ones). One said no code needed on US cars. True? Several said no problem. Looked thru my owner's manuals, etc. No radio card, no handwritten note. I ask because went thru this w/ a battery change on our Honda Pilot which decided it needed the radio code. Major PIA.

New battery isn't charging. At idle, alternator putting out 14.4 (measured at battery). After full charge w C-tek (12.9) battery was 12.6 after sitting for more than a week. I drove 10 miles. Still 12.6. Maybe BCM issue. Hoping hard reset will solve the problem. Suggests appreciated.

 

The X150 does not use a radio code.
Also, BCM is self adjusting… drive it more ;-)

 

Excellent. Looks like I need to plan some long trips. Thanks for your help.

 

I wish I had 12.6V.

 

You don't??

 

For a year it has been at 12.3V. Summer and winter. The 6 amp charger tries to pump in 2 amps for hours, but the best it will do is 12.5V, maybe. Its a H8, group 49, AGM battery. But it spins over the engine at a high RPM. Now I am using Murphy's Law. If something is not really broke, don't fix it!

 

How old is the battery? C-tek has a specific setting for AGM. Does using a standard charger (no AGM setting) cause any problems?
