PCS Light

Only the models equipped with the DRCC (Dynamic Radar Cruise Control) have the PCS (Pre-Collision System), because the Radar is the heart of the system, that being said, the U.S. Prius's are broken up into models, beginning with the II, and progressing to the III, IV and finally to the V. Each model can have packages that can be included with that model. For example, the only way to obtain the PCS, in a U.S. model, is to purchase the model V and have it equipped with the Advanced Technology Package, which includes: DRCC, LKA (Lane Keep Assist), PCS and IPA (Intelligent Park Assist). This is not based on Regions, just on which model you want, and how you want it equipped.

The switch (on U.S. models) to deactivate the PCS, is located under the dashboard in-line with the steering column, nowhere near the footpedlas.

I did the same thing, thought it was broken. Then remembered I had just reset the TPMS (tire pressure monitor system) and the buttons were close together, I had pushed the PCS while fumbling for the TPMS button.

 

GAM,

You little ripper! Thanks a lot for that. My PCS light came on today and I didn't know what to do about it.
I am taking the car in for a service tomorrow and was going to tell them about it then.

I found your post, and tried your trick and it worked! Thankyou

I never knew this button was there!

Thanks again for your contribution!

Cheers,

Lloyd.

 

Re: Blind Guy's post, if the OP cares, Toyota Vehicles : Toyota Announces Prices for 2010 Prius / Toyota was the model matrix for '10 and '11 Priuses.

On the '11, Toyota changed to spelling out the words instead of Roman numerals. The prices also went up a bunch of times from those old prices.

 

My PCS warning light comes on even when the PCS is turned off? Help? Codes have come back clear i don’t know why the warning light continues to come on

 

have you spoken with a dealer?

 

Not since last time this happened which was last year and they had NO CLUE as to why this was happening. The only resolve they came up with was to reset my radar in the front by setting up cones etc to the tune of $700....i can’t believe there are other prius owners who are having this problem?

 

did they check for trouble codes?

 

The PCS light will come on when you press in the PCS switch located under the dash beside the steering column. When you press that switch again the light will go out. Some people manage to press it accidentally. Pearl S' PCS light is on all the time because I choose not to allow the car to brake at bridge expansion joints (which it can do per the owners manual).

To locate the switch purposely you have to almost put your head on the floor and look up (use a flashlight). There are two push button switches under there, one labeled TPMS and one labeled PCS.

 

It;s not the PCS light that;s on it’s the PCS warning light.......i know the switch well, and sadly even when the system is turned off the PCS warning light comes on.

 

Yes they did check for trouble codes everything came back fine

 

have you called toyota customer service?

 

No but I’m taking into a mechanic this week frustrated

 

So, update, took it to the dealership and they diagnosed a problem with the ECU system they made an adjustment and it seemed to have worked until he NEXT DAY when sadly the light came back on.
Now they are wanting to replace the ECU system to the tune of $1500.....ugh
Anyone ever heard of this

 

no, but i would just put up with it for that price, until you can find a cheaper solution.

 

They have offered to cover half of the cost but now the light hasn’t gone back on
They said I have to fix it within the next two weeks or their offer doesn’t stand.....kindof annoying
