Reading Ford 2021+, Nissan, Fiat and Renault BCM/HFM with the ZN085 for key programming (AKL)

The ZN085 reads the BCM and HFM modules of Ford (2021 onwards, with RH850 MCU), Nissan, Fiat and Renault. The read is uploaded to the Abrites servers and the key programming is then finished off in the brand-specific software.

Procedure

1. Identify the module you're working on (Ford BCM 2021+ with RH850 MCU, Nissan HFM/BCM, Fiat BCM or Renault HFM/BCM) and check it with "Check by Part Number".
2. Make sure you have the right licence for the job: FR011 for All Keys Lost on Ford with RH850 BCM, NN010 for Nissan HFM/BCM, RR026 for Renault HFM/BCM, FN024 for FCA key programming from an RH850 dump.
3. Strip out the module, open the programmer software, select the MCU type and then the unit from the list (the manual's example uses a Renault HFM).
4. Press "Wiring" for the connection diagram and solder the CB501 cable to the points shown on the PCB, desoldering the capacitors first where required.
5. Check the connections with a multimeter, particularly the absence of any short to ground at the grey wire point.
6. Press "Read MCU" and wait for the read to complete: the data is uploaded to the Abrites servers.
7. Save the backup file of the read.
8. Open the corresponding brand software and finish the key programming from there: Ford Offline for Ford, Nissan Online for Nissan, Fiat Online for Fiat, Renault Online for Renault.
9. Remove the CB501 wires, resolder the capacitors without shorting them and refit the module to the vehicle.
