Hello dears

I am new here

I have a rcd310 it has nec 3358GJ. I tried to read it with a ft232 and pl2303 usb uart converter. I tried couple of wiring diagram.

Rx To tx
Tx to Rx
PDX to mode pin (5volt for read mode)
reset pin to gnd with a push button.

I give 12v to +bat and code pin
I give GND for 12v and For usb uart converter


I wired nec directly or wired from bottom side. I give exact 5 volt to mode pin or I connect 12k resistor +12v to mode pin.

I tried to swap rx tx wires. But No succes I cant read

Software gives INIT failed error 1

How could I solve this problem ? I cant read nec


Thank you

Thank you for answers.

Here my configuretion

Black cable goes to TTL 5v
Right side blue cable goes(RX) Usb-TTL Tx pin
Orange cable goes to (TX) USb-TTL Rx pin
Green cable Goes to usb-ttl gnd
Pink cable switch gnd
Left blue goes to switch

+12v goes to b+ and code
GND connected to chassis

I dont know its windows version issue. I will try xp

Edit: I tried xp No succes

Thank you

- the next time you have to check the model data ( 1K0 035 186AN no 0K0 035 186AN)
- you have to solder a 12K resistor------ like the picture
- you must have a push button and solder the wires (reset) ------like the picture
- solder the rx-tx wires ------like the picture
-run the software to read the NEC
- supply your car radio with 12v
- press button once for 1 sec
- read the NEC

Thank you for your answer I am so sorry Thats my bad. I will check double time everythins after that :)

But. I did your schematic but I cant read nec I dont understand. I will try today and I will share my configuration again.

By the way I have other eeprom dump if it enough to find pasword.

This is not enough for code, you also need NEC processor dump

Merci pour votre réponse, je suis vraiment désolé, c'est ma faute. Je vérifierai tout le temps double après ça :)

Mais. J'ai fait votre schéma mais je ne peux pas lire nec je ne comprends pas. Je vais essayer aujourd'hui et je partagerai à nouveau ma configuration.

Au fait, j'ai d'autres vidages eeprom si cela suffit pour trouver le mot de passe.

​change the RX-TX wires

Sory Wrong GND

Hello again me

I tried everythnig.

I swap rx-tx hundred of times
I tried a few usb-serial converter.
Reset is ok working If I dont connect to flmd0 to high and if I give a gnd to reset yes radio is resetting so its working.
I tried to connect FLMD0 to external 4-5 volts or connected to 12v with a 12k resistor I check the v850 datasheet yes its true. For programming I should pull the flmd0 to high OK I did.
Gnd is okay
NO NO NO I cant read I will go crazy.
I read other eeprom in a few seconds but this nec I cant.

I am an engineer not a noob or newbe.

But I dont understand Why not.

Datasheet says if read prohibition is enabled then yes I cant read But are they doing this prohibition randomly. Lots of people can read this damn chip. Why I am not

Really I will give 220ac to this radio and I take my tea and watch how it is burning..

If it is possible to find first 2 digit of pasword maybe I can do bruthforce but this time I have to wait safe code 2.

Is there a way to bypass code 2 waiting? I saw some tutorials to find first 2 digit from eeprom dump. For second 2 digit I have only 100 posibility.

Another posibility is SPI I saw in datasheet SPI can be used for programming.

Yes you can try first two digit operation...You need icsp programming with soic8 clip + if your programmer have only counter programming option easy decode you radio (example Upausb)
Do not give up

If it is possible Could you explain it? I have tl866ii :) I have already read radio eeprom (95128w) with this tl866ii. What should I do after that.
Also we have code 2 problem.

First connect radio power supply power on wait 1 or 2 hour wait display "SAFE"
Second power supply off read eeprom upload
dump here

I tried 0800-0899 not worked

When I flash modded bin file. Radio not openin only one time flashes the screen backlite. But its changing b50 adress.

orginal bin
AE0 ----- AE1
B1 ------ D1


After mod read

B50 ------ B54
B1 ------ 59


After Some maths. First 2 digit come 08XX but not working.
