Hey guyz ...some of you know me here and i have this problem come up after driving for almost 3000 miles on a long road with sandstorm and i got this error it says check pcs and it wont go .....in the city i used to get it but it used to disappear but now its just there permanently and it wont go even after cleaning it so many times and yesterday i tried to on the cruise and it wont work because of this pcs error ....

its a 2005 ls430 ultra luxury ..please help

 

I don't have the PCS, but with my laser cruise on my CL trim, that error usually for dirty cover, but if you've cleaned it... then something else is up. So the clear protective lense and the inner part are both clean?

 

i have gotten this a few times but only when snow and slush is building up on the little L plastic window on the front of the grill. what different parts of the world we live in huh ??

 

There's another thread going on right now on if the plastic cover is needed and somenoe posted that the piece actually plays a more important function than just protecting the sensor from gunk. It actually does something with the frequency and such, so if you've gone through some extensive sandstorm, perhaps the cover has gotten scratched (although it's clean) and the sensor is not functioning correctly now.

 

Exactly i have gone through extensive sandstorm and i have cleaned the black box behind da grill which is known as the radar detector lol but the message still wont go and i hate it ..i just want to get rid of the message and wont the pcs to work again

 

Sounds like you have a problem... going to cost you some money to fix too. As others have said... search the forum for "Check PCS" and you'll find what you need in there most likely.

 

Thank you and i will look for the post hoping it wont cost me anything

 

have you tried cleaning the BACK of the emblem also?

may be some dirt got stuck back there and it's blocking the signal?

 

Thank you but i will try to clean it once again and check...my grill doesnt have the pcs glass though :/

 

To rule out a simple problem, you need to return the grill back to stock trim. The glass is there for a reason. Are you sure you have a UL with PCS?

 

I agree. There was a thread regarding that issue that it's not a fancy plastic piece.

for those who haven't seen what a pcs looks like behind the emblem

 

Can anybody really confirm that this plastic isn't just plastic?

 

I cannot confirm that it is not just plastic, but IF it looks pitted, or dull, try Meguires Plastix on it to polish it. The stuff works wonders on the plastic gauge cover, headlights, AND I even use it on the coated wood trim inside the car. It has UV protection in it as well. I would venture to guess, having worked on these cars for a long time, that the outer cover is clear plastic. If anything is a "special material" Lexus would have it behind the clear plastic. If you drove through a sand storm, It probably looks like it has been sand blasted. Try the Plastix with a buffer and see what happens. It cant hurt anything.

 

Thanks bro yes and i do know my car is an ultra luxury and i have been driving without the glass pcs grill and never faced such error for so long but had gone through alot of sandstorm lately since then i have my cruise control not working
