Warning Lights

[blueblitzer]

I put my IS200 in for a service on Monday. They also fitted a new ball joint and shaft, and also replaced the front disks as they were lipped. I drove the car home feeling I had some peace of mind.

Didnt use the car again until the Weds.

Started the car up on Weds morning only to see warning lights come on and stay on. Handbrake, oil, light out, ABS flashing. Also the rev counter and MPG dials were dead.

I took it to Lexus today and they are saying that they cant find the fault and will be charging me for investigating and also any fix costs.

Needless to say I was shocked as nothing like this has happened before on the car and I had just spent £1000 with them, and its no coincidence to me that after thet have been working on it this has happened.

Any ideas what the cause could be? Is it correct that they are billing me?

Im going to see what the come back with tomorrow as they still have the car, if its bad news im going to write to Lexus HQ about it.

Cheers

Hi,

Thanks, sorry should have introduced myself...Feeling a bit stressed at the moment.

Its a 99T plate. No mods. 43, 000 miles, full service history.

disconnect the Battery for 20 mins........have a cup of tea, reconect and see if that clears any codes.

do you know if the car has had a new windscreen, was the car kept outside

[blueblitzer]

Yeah, the windscreen was replaced at my house on the tuesday by the RAC.....is that whats caused it?

The windscreen can cause those warning lights ? - eh .... I never knew that ! :P

Welcome to the Club tooo ! :D

[blueblitzer]

So is this the fix to take off the Battery for 20 mins?

[blueblitzer]

Lexus still cant find any issues, he ECU logs arent showing anything. They want to try and replace the ECU.

Supracharge, thanks for your help. How would the windscreen have caused this to happen?

Any help is much appreciated.

If the screen isn't watertight, odd things may happen when the water gets in behind the dash.

[Monster-Mat]

common problem if the windscreen is fitted badly, water gets down into the Fusebox etc etc.................

[Dave-Ellen]

I had this on my IS........happened once............did the Battery thing never again !

[blueblitzer]

Thanks every1 for the advice. Its still with Lexus as they are trying a new ECU on monday to rule out it out. Just have to wait and see what they come back with . Im gutted, didnt expect all this headache just from getting a new screen fitted.

[blueblitzer]

Any ideas how i will be able to prove the the RAC have made a hash of fitting the screen? Im thinking it might be difficult to prove, then Im going to get stung for even more money!!

[Dave-Ellen]

New ECU ! twill be a fortune.............Hope its not that.....

[blueblitzer]

Its 700 quid.....the manager said he would speak to Lexus GB about getting a discount as the car has done 43,000 and has full ser history.....hope not too cos im skint this month!!!

I've got a second hand one

your for £500

Joke £150.........if it helps :winky:

[blueblitzer]

Sounds like a good deal. How easy are they to fit?

[Dave-Ellen]

Not a clue..............I'm sure someone will be along to tell us !

[Monster-Mat]

firstly.........check the windscreen isnt leaking...........secondly check the fusebox isnt full of water.

Then look at wether the ECU is faulty

If you fit a new ECU you have to reprogram keys, make sure you include that in any price enquiry.

and if you purchase a used ECU from a breakers etc. then make sure it has a master key with it otherwise it will be no use.

Hi Guys,

Lexus fitted a new ECU and the problem cleared. They checked the windscreen for leaks and electrics for water and could find nothing! Im still convinced the windscreen caused this as it was replaced last tuesday afternoon and by the evening the lights were on. Sadly dont see any way how i can prove it! Any ideas?

James at Lexus - Woodford was very good. It should have been £980 all in, but he called Lexus GB and they agreed to do it with 50% discount. It wasnt good having to spend more money but that helped alot.

I still have to programe the 2nd key, they said to put it in the ignition, turn until the lights come on, switch off then open and close the door. Is this the correct method?

Didnt do it yet as needed the car for work and didnt want to be stuck if i done it wrong.

Cheers

[ColinBarber]

There is much more to the procedure than that unless the ECU is still in initial program mode?

Give the method they said a try first.
