GID decoding

[Miriada 4344]

Hi code 5855

[David Lora]

Hi,

Thanks for the code.
I need a bit more help. I could unpair my display module.
I bought a GID display, Seller said it was divorced from the original head unit, but it seems not,
because I can't activate theft protection with my radio.
I dumped this eeprom as well ST93C66.bin

I appreciate your help

Cheers

bad read mate.

[David Lora]

I didn't desolder from the board in this case. Please try these 93C66+.bin93C66.bin
if not readable I will out take from the board tomorrow.

Cheers

The file 93c66+ is ok the other one is not..

The code for it is 1802 with 6 attempts left to unpair with the timer running..

[David Lora]

Something wrong. Im using Op-com.
Just for sure
1. I have to deactivate the protection with code 5855 in the infotainment/head unit ---- succes
2. Replace display module ---Ok
3. click again deactivation in the infotainment/head unit with code 1802? I've got error message "programming failed"

From the post above, it seems like you're trying to deactivate an already deactivated head unit so maybe that's the cause of the "programming failed"?

You could try:

• detach new GID (currently set to 1802)
• reattach old display (currrently with no code aka "delivery state" or "unmarried" - as is head unit)
• program both to new GID's code 1802 via EHU (both EHU and DIS set to 1802)
• remove old display
• attach new GID

Check "mid-speed CANBUS configuration" in both head unit (EHU) and display (DIS) so they have the same entries enabled.
Your GID might have come from a car with with DAB whereas your EHU might not.

Clear fault codes in both units before trying to pair/unpair.
A tell-tale sign that mid-speed CANBUS configuration is an issue is a fault code like "maximum configuration list not programmed".

Alternatively, you could:

• detach new GID
• set EHU mid-speed canbus to only EHU (no display, DAB, etc.)
• program EHU to 1802
• reattach new GID

Personally, after pairing new equipment for my car I like to reset then recode them to the code shown on my security car pass.

Thanks for your detailed answer,but still not good.
I tried what you wrote, but no luck.
Whwn I set the EHU with code 1802, than attach the new display I still hear beep in every x second , the display shows radio safe.
The difference beetwen devices in the measuring blocks the new GID display shows "security wait time" --"running".
The old display and EHU says this "not running". I don't know what does it mean.

Can anyone confirm that this is the right code 1802 from this dump 93C66.bin

Yes pin is 1802

[David Lora]

Thanks for confirmation, I have no idea how can I put this display in delivery state
