SPC560xx MCU replacement on JLR RFA/KVM modules (JPLA, K8D2, J9C3, M9R3) and bench configuration writing with ABPROG

This is what you need when the RFA/KVM module has a locked or damaged SPC560xx processor: instead of replacing the whole module you fit a new SPC560 and write the configuration straight onto the PCB, on the bench, with ABPROG. Compatible with JPLA, K8D2, J9C3 and M9R3 modules from 2018 to 2026 on Defender, Velar, Evoque, Discovery and Range Rover.

Procedure

1. Remove the RFA/KVM module from the vehicle.
2. Open the module and remove the original SPC560 chip from the PCB.
3. Fit a new (virgin) SPC560 chip onto the PCB.
4. In the JLR Online software open "Special Functions" and choose "MCU (SPC560xx) replacement of KVM/RFA".
5. Select the exact type of RFA/KVM module you are working on (JPLA, K8D2, J9C3 or M9R3). Once selected, dedicated buttons appear.
6. Press the wiring diagram button to see how to wire that specific module.
7. Connect ABPROG to the PCB points following the displayed diagram, then connect ABPROG to the PC.
8. From the JLR vehicle menu in the software, start writing the configuration data to the new processor, on the bench.
9. Wait for the write to finish without disconnecting anything and without cutting power.
10. Close the module up and refit it to the vehicle.
11. Reconnect the AVDI to the OBDII and check with the diagnostics that the module responds and has no leftover DTCs.
