ECO Does Not Work

[excash]

I have a car with non-working Start/Stop ECO.
There is only one code in the ESP ECU ABR.
C252900 one or more signals sent from the control unit N93, the central control unit of the gateway on the CAN bus, are invalid.
I have attached the coding data from ABR and CGW, which I took from DTS.
Please check.
Any advice would be appreciated.

If anyone has this problem, I changed the front SAM and everything is fine.

ECO is a function. It is not located in any of the control units. Typically it includes about 7-8 blocks. Also, the prerequisites for running the function must be met. Xentry has a process for polling this feature. Run it and see what's WRONG. Or it can simply be disabled using coding.

In Xentry, on the left panel, you can select your problem. In German, in "Kundenbeanstandungen". Then Xentry connects to all ECUs that are involved in this function. Now you can look in the "Ringspeicher", where you can find the reasons why this function does not work. Most of the problems were caused by faulty batteries.
