Check Vsc , Trc & Warning Triangle.

[Kineavy]

Hello Folks,

I have a LS430 on 05 plate. The car has come from the Rep. Ireland and once it's on UK plates it will be for sale.

The mentioned lights came on and both o2 sensors have been changed. I tried disconntecting the Battery , the paperclip trick and pulling the fuse but the lights are still on . There is no EML on. Just the VSC and TRC.

Has anyone got a solution? Does it need resetting and checking for more faults with a Diagnostic machine?

Thanks in advance.

If the Battery has been disconnected for a period of time this may happen but usually everything resets once the car has been driven for a while.

If this fails to work then you would need to have the fault codes read, doesn't have to be Lexus just a good garage with a decent code reader.

Please also be aware that you may not offer items for sale on the LOC UK unless you are a paid up gold status member :)

Cheers for that. I was not offering the car for sale. Just introducing myself and how I aquired the car.

Each time those warning lights have come on in my mk4, it's always been after the Battery has become a bit flat. A charge up or a good run should see you right. (Or a new Battery!).

yes agree with the above - weak Battery can create all sorts of gremlins - recently my smart key for my 430 wasnt working properly (keyless entry etc) - even after changing the Battery it was a bit of a hit and miss - somtimes it would lock and lock - sometimes it would take 2/3 seconds.

eventually it settled down on its own accord after 2 days and is now working perfectly.

No problems with Battery from what I can tell. Granted the car has not been driving for long periods over the last 2 weeks but starts on button. 20 minute max run at the moment.

Even though the Battery has enough power to start the engine, I believe it needs to be holding a full charge in order for those warning lights to go out. I was doing some DIY for quite a while on my car once and I inadvertantly let the Battery drain down a bit by leaving some lights on. It started up ok, but the VSC light etc, came on. Once the car had been given a good run the VSC lights disappeared and never returned. This has happened twice in two years when my Battery was a bit low.

What you reckon is a good run? 10 miles? 20?

When you did paper clip did you insert in correct pin's? I did mine by following a link didn't work then i went on to another link they showed it inserting into different pins and it worked for me.

[Kineavy]

I put it 3 from left on top and 5 from left on bottom.

[9690phil]

Thats wrong. Its 2top 4bottom

[Kineavy]

With the wider end regarded as the bottom?

[9690phil]

Dont go of my saying, but im sure your way was wrong. I followed link on youtube on toyota but that was wrong. I found a diagram some were on a lexus forum and that was correct and cured it.

[9690phil]

Yes. I took my obd out so it was hanging

Down found it easier as might eye sight is terrible. But if you got your top wire in say 2 from left. The bottom wire is further over to the right for eg twenty past twelve on clock face. Dont know if makes sense? Were did u get your info from 3+5?

[9690phil]

Try 3+5 but other way round? Cant find the link i used but it should put it out?

Mine came on after being on diagnostic.

[Kineavy]

Got it from another forum. The afs light flashes when I turn ignition on..?

[Titch LS]

James, I would think 20 miles or so.

[9690phil]

Different to mine then, my vsc light would come on soon as i drove about a metre. When stopped and turned engine off then started engine no light on. Soon as drove off light on.

[Kineavy]

Phil that's the same. Drive metre it comes on. Restart engine no light until you move.

[9690phil]

Any luck clearing vsc?

[Kineavy]

Not as yet. Going to take a drive this morning. Failing that I am going to have to get it on a machine and see what the story is.

[9690phil]

Strange should put it out if your putting in right terminal's

[9690phil]

Try 2nd from left on top

5th from left bottom that did mine

[Kineavy]

I am now thinking that maybe the other sensors are knackered. Ones further down the exhaust.

[9690phil]

If its had a full diagognosic check this has prob put this light on?
