Volvo renesas M32C read: VVDI-Prog vs. Londor vs. SMOK

What’s the best programming tool for Volvo CEM R32C R5F64524KFD read?

Xhorse VVDI-Prog?

Londor K518ise?



Look here:


VVDI Prog: Need luck?

Xhorse support: M32C renesas don’t work with vvdi-programmers.

But received some complaints: tried to read Volvo cem from 2013 s60 USA. unsuccessful



Volvo dealer software: Confirmed!

How to use volvo software to read this M32C:

Read 93c86 (nearby M32C)


You can get PIN code for M32C renesas from software log file
But I tried with an Chinese one I got no details
You have to use original volvo software with an official account to get correct logging


Good to know:

The Di-CE uses a Renesas M32C/85 microprocessor which has internal flash memory. This flash memory is used for storage of the firmware image alosng with device specific configuration data. Flash block 1 is used to store, among other things, the serial number and the bluetooth id of the particular DiCE. If you’re getting all zero’s when the Di-CE is connected to your computer then it’s likely the contents of flash block 1 have been erased.


This can happen under unusual conditions, I’ve caused it once by adding a bluetooth card to a clone Di-CE. If you happen to cut power to the Di-CE when it’s in the middle of rewriting block 1 then you can end up with an erased block. In my case it was likely recreating block 1 with the bluetooth id when I turned it off.


One of the other pieces of data stored in block 1 is a “flight recorder” of Di-CE hardware failures. When the software detects there is something wrong with the hardware it logs it in block 1. Again, if you cut the power when the log is full and it needs to rewrite block 1 you can end up with an empty block 1.


I’d be inclined to blame the crap clone hardware rather than malicious Di-CE firmware. The scanner is recoverable if you have a programmer for the M32C/85 and know the programming key, if one has been set.



Londor K518ise: Confirmed

You can read M32C renesas with Londor k518ise and Kprog 2 adapter 
Steps can be:
Lonsdor K518ise – adapter – mcu – renesas – r32c/m16c/spi – read flash – read dataflash

the wiring:


note: cut off the power when wiring.
use needle 1 of the adapter to connect gnd
use needle 2 of the adapter to connect vcc
use needle 9 of the adapter to connect rxd
use needle 10 of the adapter to connect reset
use needle 11 of the adapter to connect txd
use needle 13 of the adapter to connect sclk
use needle 14 of the adapter to connect cnvss
use needle 15 of the adapter to connect busy
remove this chip when reading data. cut off the power supply and wire the chip back after reading data.


Smok: Confirmed!

Smork can read CEM Volvo M32C. attach images.
