An Renault Kadjar 2017 spare key job was attempted using an Autel MaxiIM IM608. The user started the procedure to read the PIN, but the process failed. The ISK is unavailable, and the BCM is now in a virgin state.
The DFlash (64 KB) was saved by the IM608. When the DFlash was later read using SMOK UHDS, the data appeared different from the original file saved by the IM608.
Attempts to repeat the key learning procedure and add a key were unsuccessful. The BCM MCU is SPC5606B (0N13E), and it is locked for both read and write.
The immobilizer status currently shows:
-
Keys: 0
-
State: Virgin / not learned
When trying to retrieve the ISK with the SMOK tool, it reports “ISK target not found.”
Is there any solution to recover the BCM or complete key learning in this situation?
Note that:
Renault after 2016 are the worst card to work on. You must fully charge car or user additional power supply. Kadjar is much more dangerous because it cannot be backed up after a failure.
Solution:
Once dflash is virgin state, Renault server can bring it back to life. You can learn UCH online. Someone with an online account at Renault (who works for the dealer) can relearn the UCH and reprogram the key. Online renault should adapt it to car and you retry to learn. Once you will learn uch and relearn original card – after that you can start once again with adding spare card.
Option solution: Autel support (for Autel device only)
The car is back to life.
If this happen to anyone don’t waste time trying to restore this with available tools on the market.
Read ecu in boot mode sid310 and get someone to extract ISK is not working.
Only way to code this car is 32 digit pin number that sofar im aware its only available in BCM or available with Renault.net.
Ecu sid310 holds ISK number but its not 32 digits. Its 16 and its used to virgin ecu I believe with different tools…Not for programming immo..and I can’t see any available tool that can extract 32digit pin from sid310.
Bcm is locked for reading on bench. I make up jtag connection and tried with Smok ..CPT ..VVDI.
Smok and CPT can see mcu ID but then a message appears mcu no connection or locked for reading.
So can’t even backup data before key learning.
So don’t waste time taking it out.
Bcm Mcu mask 0N13E spc5606BK.
Found source to get pin through Renault. But Autel support was quicker.
Once I opened thicket through Autel.com and report my issue. Few days after guy emailed me to upload logs from fail to add key.
1 hour later he emailed me back that data is corrected now on server for my car.
Try add again and 32 digit pin was displayed on im608.
Continue make dealer key and add two keys successfully.
No additional coding needed it. car started as normal.
Autel support fixed the file on their side and that allow me to continue the job with Autel im608 and finish the learning procedure.
They adjust the data on the server. maybe the software version of this bcm was the problem and they just add it to server manually.
I am happy that the problem has been solved, the truth is that it encourages us to continue using the Autel device.
