I retrofitted the alarm on my 2015 BMW F11 car but now I have a problem detecting the ECU, when I run ISTA it shows ECU FZD

But when I run esys the ECU FZD does not appear

attachment: error in ISTA

does anyone know the solution

thanks

Can you provide a bit more information?

Did you change the FZD (A21) from a basic to a "high version"?

Did you install the alarm horn (H1) in the right rear bumper area?

Did you run the LIN Bus wire from the H1 to the FZD?

Did you code S145A option into your FA?

What does ISTA list as your error code for the FZD module?

Yes

No, I have installed Alarm System Retrofit

Did you install the alarm horn (H1) in the right rear bumper area?
No, I followed the instructions I attached for the installation

Did you run the LIN Bus wire from the H1 to the FZD?
I used the original cables that come with the retrofit

Did you code S145A option into your FA?
No, I code S302 in FA

What does ISTA list as your error code for the FZD module?
attached ISTA_ERROR

thanks

This means your issue with the FZD in ISTA, is independent of your alarm wiring.

On page 13 of the installation manual, it does show removal of your FZD module to route your alarm wire to your rearview mirror.

I would recommend that if you did pull the FZD module, to remove it, and try to reseat all the connectors. It looks like the connector that has the bus wires isn't plugged all the way in.

hello M_Bimmer

I only had the opportunity today to remove the FDZ module and I verified that the A21*2B connector does not have the CAN wires that connect pins 9 and 10.

I will have to make this connection between connector A21*2B and connector A16*1B.
