Thanks Sami, That explains it. When I had the TPMS valve replaced in one wheel 3-4 years ago I had to take it back because it kept showing a 'low pressure' warning. They said they had changed the valve and it seemed OK - until a couple of years ago when the 'Check System' warning appeared. So it is probably the valve playing up again. I'll have a tyre place check it out, but as long as it still does not affect the MOT I can put up with the message.

Thanks for your response. I got hold of an OBD reader and using an app on my phone I found some errors relating to ABS, but nothing for VSC. However, I cleared the errors shownand this seems to have removed the VSC notification. On another note, I also have a 'Check System' notice along with a tyre and engine symbols. These have been displayed for the last couple of years since I had a TPMS valve replaced on one wheel. This has never caused an MOT failure, but wonder if you could suggest how I may clear the message - using the OBD if possible.

The 'Check VSC' warning accompanied by the dash light has yet again appeared on my 2015 GS300. This has been happening intermittently for the last couple of years or so. It comes on then usually disappears again within a few hundred miles, and does not appear again for a few months (sometimes longer). As I understand it this is a MOT fail (if the warning is apparentat test time). Anyone else experienced this issue, or more importantly have any suggestions to try and turn it off.

I recently posted about the power steering on my 2006 GS300 failing after the battery was recharged following it going flat whilst left stood up for a few weeks. The other day, after it stood for a week or so post charge, I started the car to take it to a garage for diagnosis of the problem, but hey presto the power steering was working again. After a couple of more days I went to take the car out and neither of the two key fobs would register - so I had to open the car using the 'key', with the alarm going off and an error on the dash saying no key located resulting in my not being able to start the car. The batteries in both fobs are relatively new, so any suggestions on best approch for rectifying this issue would be appreciated.

Once I start the engine,t he only light that remains on is the P/S light - everything else seems to operate OK,

It is a relatively new battery (18 monthsor so). I tried disconnecting it following your suggestion and find that the P/S is still not operating and the light is still on.

During the recent cold spell I had not driven the car for a coupleof weeks and when I went to use it the battery was flat. I charged the battery and all was well for a couple of days when driving it. Yesterday, after a few days of being parked p, when I started the car the P/S light was on and I have no power sterring. What do I look for first to try and identify the problem. 2005 Lexus GS300

Sorry - meant Techstream - senility at its worst 😕 Hopefully someone close will have it as I don't have a laptop to run my own copy - if I had one.

Does anyone have the Techsmith software and live close to the Newport - Brecon Beacons area of South Wales.

Sorry for the delay in feeding back. It was the battery 👌 What threw me was that I had charged the battery a few days before the fobs stopped working, but when I took it off to take it in for chacking it only had 2.5Volts in it ?????? A local workshop put it on their charger/conditioner for 24 hours and it had 12.8Volts when I re-installed it. The fobs worked and the VSC warning both were resolved and the battery has held its charge for the last few days - so all I have to do is to get the new TPMS registration error resolved and we are back to norm. Thanks for all your input.

Thanks guys. It was brand new only 6 months ago - but I'll get it checked tomorrow. (Someone else also suggested that the 'Check VSC' warning may be the battery asit only comes up intermittently)

Thanks Guys. Unfortunately the batteries were the first thing I checked - and they are both reading 3 volts.

I am hoping someone here cal give me an understanding of what might be going on with my 2005 GS300. I fitted a new Enduroline 069 75AH battery in August 21 - recommended by a friend - and then a couple of weeks later moved house but in the meantime had been using the car regularly. After moving house the car stood for a week or more without being driven and when I went to use it againa I tried to unlock the car using the fob without any success, so I tried the spare fob, and again no success.Thinking it might be the fob battery I changed it in both fobs - but still no success. I used the key to unlock the car, and the alarm went off. The dash display had a message - no remote key found. I closed the car and within a few minutes the alarm silenced and the car locked. I left the car and used my wifes car and when I got home a couple of hours later I tried again. The first fob didn't work, but this time the second did. All was well for a short while until yesterday when, after having used the car a few times last week, I had exactly the same problems with neither fob unlocking the car until after numerous tries over the next 30 minutes, one of the fobs worked. I used the car covering about 10 miles, and on my return parked the car, turned the engine off and locked the car. 2 hours later one of the fobs successfully opened and started the car again, but the second did not. This morning, one fob opens the car but the other doesn't. Any suggestions to resolve this would be appreciated. (I do have another problem with an intermittent 'Check VSC warning which started about the same time, but I'll deal with that seperately)

Thanks guys. I have a jumpstart pack and the neighbour has a spare battery - so sorted. I will of course heed your advice and BE CAREFUL 🤓

I have to replace the battery on my 2006 GS300. What issues am I likely to encounter or should I look out for with the electronics of the car when I disonnect the battery. Any advice??
