How do i reset the Jaguar XF battery monitoring system?

Let's walk through resetting the Jaguar XF's battery monitoring system (BMS). First, make sure You've got the radio code for Your XF before You disconnect the battery, as well as an accurate clock handy. When You've got the new battery installed, set the time and enter in Your radio code. If You don't have one, just put some random stuff; after three times, the display will show PLEASE WAIT, and You can use the backdoor code: press ">>", "PTY" and ""A.MEM" at the same time, and wait for 2-3 seconds: Your radio should turn on. Now You'll need to reset the EPB: Start the engine, and You should see a message stating NOT CALIBRATED or APPLY FOOT AND PARK BRAKE on the instrument cluster. Lightly press the foot brake, and apply the parking brake using the EPB switch. Release the foot brake. NOT CALIBRATED should no longer be displayed. Apply and release the EPB 5 times to ensure no error is present. After this, the BMS itself should be functioning properly, and the ECM should not be displaying any DTCs.
