H243 Lane Assist change to Last Mode

[Handed3219]

Lane Assist is an safety feature which works fine on a highway but on other roads it's hit & mis. Therefore I want to change mode from reset to last mode.
When connecting with Xentry this option is available within the multifunction camera MFK ECU which is using the MMPC213.smr-d file.

When connection to ECU EZS167 for temp disabling the firewall security level 3B I still can't read out the MMPC213 ECU and results in an timeout.
STAT: The D-PDU API call has failed; DYN: PDU_ERR_EVT_RX_TIMEOUT: Indicates that an expected response was not received within the defined timing window (307) ErrorCode: eRT_PDU_API_CALL_FAILED ( 0x0000D090 )
To be sure I've checked the MMPC213.smr-d version and build, and it's the same as Xentry is using build 02.03.62 date 2021-08-24T0819.

I've followed the correct procedure with first temp disable the firewall and then connection to this ECU but somehow I can't connect. Can someone point me to the right direction? Much appreciated.

Are you using Monaco DTS? You should be able to use the ESZ Authentication button to unlock the firewall and connect to the ECU.
Are you sure you have the correct ECU? And it's not SMPC213.

That's correct and I've changed the following setting which is persistent after hard reset, but it wont go to last mode yet.

mmpc213
007 VANS coding Write - ALDW Reactivation Mode - Last Mode

I would still check for the presence of the module. I still think your ECU is SMPC213.

You are correct, but changing the setting in my earlier post which are persistent after ECU reset wont change it to last mode. Still the ALDW mode is activated after starting the car.

Here is something I found today while using Xentry Sim. There is an option for the dealer to do it! Question is, is this only available through Xentry? I won't be in a position to try on my cars as I am travelling for the weekend.

Ok, I just performed the function and can confirm it changes LDP UI Variant to Variant 10. No Hardkey, Warning On/Off, Intervention Mode, Last Mode. It was originally as Variant 6.

I have it working as last mode finally. I also validated it under DTS and it showed 10. Must be the Security key that needs to be unlocked for that to be changed, which Xentry does for you.

How to get a code for a special mode?

I can make a calculation based on the VIN code.

I did this on my X167 with DTS but there was no result, LDP remained activated while VANS partition was already in last mode. I changed it to SMPC213 because my car doesn't have MMPC213. Any suggestions?
