LHRDA and RHRDA?

Left Rear Drive Assist module
Right Rear Drive Assist module

But today i got false brake so... still not perfect. Its also the blind spot modules

LHRDA/RHRDA: i suppose they are part of the rear collision warning system? If I look at the description of the three lka modes, I would expect them to only influence ELK mode ??

Also for ELK

Well, I tested the following yesterday on an 86 km trip.
-all sensor at the rear disabled
-blind spot disabled

Then I used Lane Departure Assist and Emergency Lane Keeping mode with various sensitivities.
Purpose: to test what sensors are involved in the two LKA systems, particularly when going back to the previous lane after an overtake.

In general, both modes worked about similar with either sensitivities. High sensitivity definitely alarmed more often and more often unneccesary.

Specifically, when returning to the lane after an overtake (no cars next to me and ahead of me, car faster than the vehicle overtaken, overtake takes place at least 3 seconds after passing, indicator on before approaching lane markers), both LKA modes still provide audio and visual warnings with occasional steering when going back to the initial lane.

Conclusion: LKA overrides the fully disabled rear sensors / warning systems.
Funny thing is it happens in LDA mode as well. This does not fit the description of LDA at all, which is basically the classic LKA intervention mode using the front camera only.

Hi

Sorry for dumb question but new to MG4.

Picked up a preowned MG4 last week and was told the latest software updates would be carried out but checking later I found the car was in version R40 and understand R63 is latest firmware for Trophy in UK.

I also see lots of posts about SC077 LKA update. Is this part of R63 or something different and what should I be looking for in the infotainment system in this regard to check?

I want to make sure when I contact the dealer service I know what I'm asking for and can check they have done what I've asked for. I read that for the the SC077 update the dealerships are contracting customers to get this done.

Many thanks

The individual modules in the car have their own versions and that information is not accessible to ordinary drivers. (Search for SIPS.) SC077 probably updates a number of modules but i do not believe this includes the infotainment module. R63 is the latest Trophy Infotainment version but you may not get it because MG will only lay for the update if you have what they consider a warranty claim. Otherwise you are at the mercy of the dealer who may ask to be paid to do the update. in your case your dealer is wrong to say R40 is the latest version. Note there are side-effects of software updates

My Trophy is on R33 and as it works ok I am not asking for an infotainment update but will insist on SC077 today at its second service

Many thanks for the info Martin. So I guess from what you are saying I can't check in the car if SC077 has been installed or not.

If LKA doesn't try and kill you ... then SC077 has probably been done.

Pretty sure it's not been done as I tested it and the wheel was grabbed out of my hands in a couple of occasions when I tried to cross the centre line
