Twingo IAW5NR.T1 Renolink

[credoline]

Hi friends. I need to read eeprom in this half hybrid Renault ecu. My question is: it is possible with Renolink (DDT2000) to reset eeprom in ecu to virgin state? If yes, how? I am found some commands for ecu reset but not any of them look to me as immo data reset.
Thank you

no mate. i think. io terminal can do this. or manual.

What is pin OSC for ? SPI eeprom do not have pin OSC.

Try to find on the net about 95160 pin connection. But it is not the best solution cutting those gold wires and read eep.
Iot can't do it. Renolink... maybe... the red one. I did not try.

I know all pins of SPI what are, OSC pin not exist. SPI have CS chip select, SO serial data out, SI serial data in, GND, VCC, SCK serial data clock, WP write protect, HOLD suspends serial input. For reading its needed SO SI GND Vcc CS SCK. On upper picture CLK is SCK, but OSC is what ?

Osc is the pin where the interface that you are reading with sends the clock signal from an internal freq generator. Like a quartz generator
I've tried to make it off once, gathered all info about that ecu, but I have solved it by rebuilding all the solders of pins on the green (normal) pcb. And the car works untill today. That ecu has cold joints. I know, you will have to clean all that laquer on the pcb, to rebuild all the joints. Follow the main drivers and resolder all, as good as you can.
