P1582 Flight Recorder data is stored if any of the following occur:

 

1. Inertia Switch is activated
2.Throttle 'Limp Home' mode
3. Engine starts and stutters
4. Engine fails to start
5. Engine stalls

 

If any of these have occured, the stored code is showing that relevant data is stored. Dealer level diagnostics is required to interrogate this data. 

 

If non of them have occured, check:

 

1.Inertia Switch to ECM circuit for a short circuit to B+ voltage
2.Inertia Switch failure

 

If you clear the code and it doesn't return, then a temporary out-of-range signal has been the most likely cause.

Trust Me same code, same explainatrion for a jag but couldnt find a specific one for Jag.

by the way that code isnt listed in Autodata or anything like it, they expect P1*** to only be accessed by Jag main Stealers
