Immo connections

Unread post by Sponk »

Bypassed the immobilizer in the EUC, I did this a while ago. Have since tried to code new keys without success.

PP2000 write attempt fails no matter how many times I try and no matter what transponder I try with (ID-46).

Tried to "reinstall" the old immobilizer again (95160), and then again tried to code the key, but with the same result.

The key code is correct. The antenna is measured through and there are no fractures.

Is it possible to get the wire information from the antenna connections to the BSI?

Why was the immo bypassed & why are you putting it back on??
Did you write the original dump back to the ECU?
Are you using blank virgin chips? not all ID46's are the same, they need to have the correct logic on them or they may not program.
The antenna wires connect directly to the Comms unit behind the steering wheel then the information is transmitted from there via the CAN, there is no direct connection from the antenna to the BSI.

Because I didn't have the key and because it could be that there was a conflict, since it was bypassed in an "abnormal" way.

Yes rewrote the original.

No, using "remote controls" from other Peugeots.

Ok, thanks for that information 👍

Are the remote controls brand new & unused?

Used. So you are saying that the transponder code is not stored in the ECU, but rather that the code is stored in the transponder?

The transponder locks to the car when programmed, it will only ever re program back into the car it was originally programmed to.
They can be reflashed & virginised with the right equipment but apart from that you need to use new & unprogrammed remotes or chips.
Used remotes will be causing the error message.

Believed that the transporter responded with a code that was stored in the ECU but ok 👍
