Volvo CEM L Help - Hale00 - 15-10-2022
Hi
I have a 2004 V70 AKL, I was expecting the older style CEM with 28F400.
This is the CEM L with 93c86 and Renesas MC32.
I can't get a read on the CEM itself, possible that the mc32 has security bytes I need to get to read. Encrypted.
And also any info that might help in getting what i need to read this, equally if anyone has VIDA online access i will listen to that.
Pin out for VVDI Prog maybe?
As always, I appreciate the help

The 93c86 I can't get anything to recognise the eeprom to make a transponder. For a v70 I only have the 28f400 showing or the newer version 2011+
No coverage for the 93c86, which is why I need the CEM data as with Autel I can do OBD key learning along as I have the dumps first
Can you take a look at the eep to see if you can get recognition?
