[andrassh]

Hi! I need to change the ECM on Opel Corsa B, engine X 10 XE, and I need the securit code! OP-COM cannot read, said that the EEPROM is locked!
Can I read out the eeprom with programmer?
Thanks!

This is immo1 with HC05B6. Read with UPA or xprogm

Cannot read! Upa said "Vpp out of range"!
Need help!

You must cut 2 circuit in order to read with upa.

Isn't the same module! I see you are from Romania.. Can we talk in romanian? I could explain better! I put some pictures of my module!
Mersi astept raspuns!

[lupu_sandu]

Is same shit. Post picture of back of board.
In romanian we talk only on PM, not here

[andrassh]

Here are the pics! I think is a difference between the two panels! look where the red arrow is(left side, down)!
Thanks

Put external power on immo:
- pin 5 +12V
- pin 9 +12v
- pin 4 GND
Do not connect pin 9 and 5 from upa anymore.
Try to read again without lifting any pins.

[andrassh]

still cannot read... even with power supply

>>Do not connect pin 9 and 5 from upa anymore.
upa-Pin 5 to hc05-Vss must be made, it's GND!

Can you read inmo memory on ecu? maybe can you find inside.

[andrassh]

Ecu will be replaced anyway! I found a blank immo so problem is solved!
But I am still curious how to read out that HC05B6 onboard! Next time I will take it off!

I think you should not bother yourself about how to read that MCU in-circuit... Just desolder it next time and use Universal ETL Programmer. I think that would be much easier way for you... ;-)
