Help to active LKA on FF3

[gonghao]

Hi,

I met a problem that the ACS has been active and works well, but there is something wrong for the LKA. The traffic sign recognization works perfectly, but the LKA is not working. In IDS there is no error related the IPMA module, and when I power on the car, everything is well, I can use the LKA switch to choose the mode, but when I start the engine, there is an error shows, it said that there is something wrong for the LKA. I don't know why.

I've edit IPMA configurations via UCDS for DE00 part to fit my car, but nothing happened. In my IPC, I can set the strength and sensitivity for the LKA, but when I changed the value, the value cannot save, the default value is NORMAL, and I changed to HIGH, but after seconds the value changes back to NORMAL. I think this may a problem. I don’t know why. I also look the configurations in PSCM, I found some configurations about LKA is DISABLE, but I cannot change to value to ENABLE. I don't know is it related.

Do you anyone have any idea about this situations? Is it related to BCM configurations?

Thank you very much.
