Check VSC/Engine light on - safe to use Carista OBD2 code reader?

Recommended Posts

Hi, my engine light + TRC light as well as Check VSC have all come on today.  
I have an old Carista OBD2 code reader and app that I used for my previous car (Skoda) and I was wondering if it is safe to use to read codes on my 2006 Lexus LS430. There are no defects when driving apart from features that use the VSC system (radar cruise control etc...) not working.


I have also read online that things such as the fuel cap not being shut properly can cause issues like this but this happened just before I was getting fuel and the tank must have been fairly empty as it was quite a few miles after the "low fuel" message when checking the estimated miles to empty.

Yes, it is safe.

OBD2 is an industry standard, not something specific to Lexus, so there should be no problem at all.

Cheers, I knew they’re not specific to lexus but just wanted to make sure as i’ve seen posts where an independent garage has scanned them and somehow it led to more issues.

1 fault found and it is indeed the reasoning for the lights; PO430 "Catalyst System Efficiency Below Threshold (Bank 2)".

It's obviously something to do with the exhaust system and reading online it appears that it could be a hole in the exhaust, typically found around the Y-section. I have cleared the code for now and took it for a short test drive and nothing reappeared, all features including radar cruise control working as intended.

I imagine the lights will come back sooner or later but for now I will see how it goes as there is no obvious signs anything is wrong whilst driving (although there may well be a small blow in the exhaust).

I had a big couple of blows from my Y section and further up…nothing deemed an MOT failure which I found staggering. They were proper holes.

I’d recommend fixing the exhaust…maybe an O2 sensor is failing…

My LS400 failed an MOT 2 years ago on emissions at idle. I replaced the air filter and ran Cataclean through on 1/4 tank of fuel. 
Passed on retest and no further problems.

Y section was a later issue.

    • 10 years of Lexus design: from spindle grille to spindle body
      After 10 years as a defining style feature of every new Lexus model, the famous spindle grille is undergoing a transformation. In tune with a new era of electrified vehicles, the distinctive shape is evolving into a new “spindle body,” as seen on the upcoming new generation Lexus RX SUV and the all-electric RZ.

      The spindle grille has been an unmistakeable Lexus feature since it was first revealed on the LF-Gh concept model of 2011, the basis for the fourth generation GS executive saloon that was launched the following year. Since then, it has been constantly adapted to suit the character of each successive Lexus model, with different mesh patterns, dimensions and finishes.

      Speaking at the time of the grille’s debut, the then Head of Lexus Kiyotake Ise said: “You should be able to identify a car as a Lexus immediately… Instant visual recognition, for example, is the reason behind our spindle grille. It may look aggressive at first glance, that’s intentional, but it also conveys its boldness with sophistication and elegance.”

      It has progressed to become a hallmark expression of Lexus’s L-finesse design, adopted not only for road-going cars, but also incorporated in the futuristic Skyjet spacecraft created for the Lexus-supported movie Valerian and the City of a Thousand Planets and adopted as a design motif in the Loft, the award-winning Lexus and Brussels Airlines lounge at Brussels Airport.

      Today, the original grille concept is the starting point for a more radical application of the spindle shape in which it becomes an integral part of the vehicle’s overall design. This “spindle body” approach is part of the Lexus Next Chapter design for the all-new RX, where the grille is reinterpreted as a seamless unit that flows into the bodywork. The lower section retains a mesh pattern, while the upper section takes in the lower edge of the bonnet; the Lexus emblems sits at the centre of the spindle’s high pinch-point.

      The same concept has been applied to the RZ 450e. As a battery electric vehicle, this requires less cooling than a car with a conventional engine, so the grille has been dispensed with, giving the designers greater freedom. Nonetheless, the spindle shape remains prominent in a central front panel, finished in the car’s body colour. Its impact is heightened by the adjacent frontal areas being contrast-finished in black, the low bonnet line and more boldly shaped front wings.

      On both models, the spindle generates lines that flow back from the front of the car through the bonnet and headlamp units to create a strong and distinctive frontal appearance, reinforcing the brand-defining ambitions of the original concept.
