UPA-USB script for eeprom data recovering in the BCM of the Jaguar XF car with MC9S12XET256 Motorola MCU inside in the BCM.
If you have a Jaguar XF car (old and restyle), then you are doomed — a strong voltage drawdown or disconnection of the battery terminals, your BCM unit will most likely not survive.

Jaguar XF cars of the first generation have two BCM units installed:
1.Main — BCM(CJB) is located in front of the passengers legs (ids dx23-14B476-xx, cx23-14B476-xx).
2.Auxiliary — BCMB(AJB), located in the trunk on the right (ids dx23-14d628-xx, cx23-14d628-xx).
Both of these units have the same breakdown-the processors EEPROM memory can fly off with a strong discharge of the battery or when editing the configuration.
Both of these units control almost all body electrics and are part of the immobilizer of the car.
In case of memory problems, any glitches with electrics are possible:
1. The ignition turns on, but there is no start
2. The windshield washer stops working.
3. The central lock stops working.
4. "Loss of the key" and the inability to start the car.
At the same time, the keys are not lost anywhere, they are registered in the KVM keyless access unit (you can verify their operability by pressing the headlights on the key).
There is no need to rewrite the keys in this situation.
Restoring the block and memory layout is the only solution.
Buying a new unit does not solve the problem with the next voltage drawdown.
Owners of this car need to monitor the condition of the battery and avoid removing the terminals from the battery.
To run the script, an ORIGINAL programmer UPA USB is required. The script does not work with fakes!
When purchasing the script, please provide the serial number of the programmer. The script will be tied to it. You can always find the serial number in the lower window of the Uuprog program when the programmer is connected.
1. No Refunds or Modifications for Digital Licenses
Activated modules or licenses cannot be returned or refunded.
If an incorrect key or device number is entered by the customer, the purchase is not eligible for return.
Licenses cannot be modified, transferred, or reissued for another device under any circumstances.
2. Irreversible Order Processing
