Is200 Poor Cold Starting

Hi everyone, I have searched this subject but not really found anyone with exactly the same problem, our IS200 has been fine all summer but now on the cold damp mornings rather than starting within a few seconds of cranking it will fire then stop. Crank again, fire but wont keep running, repeat 3 or 4 times then eventually it runs. Alternatively if I just keep cranking for 10 to 15 seconds rather than letting the key go when it fires, it fires a few times while cranking then starts. Battery voltage is fine and it cranks over at a good speed.

It has done 90k, full service history, cambelt replaced in the summer, the engine management warning light is OFF.

I have ordered an ELM unit and Engine Check software to see what the various sensors are reading, I guess there wont be any stored error codes as there are no warning lights showing. I am new to electronic engine diagnostics but I am an experienced electronics engineer.

Thanks in advance, Martin

when was the battery replaced??

Hi Rob, the car is a late 2002, I cant find a date on the battery, it has writing in Japanese with some English, there is a number on the top label that says 140502G could that be 14-May 02? It has a condition indicator that shows a blue ring.

I will get my test meter and measure the voltage while cranking.

the condition indicator should not be relied on as its not reliable by any means.

a voltage drop should give you and idea but as you know it wont show the battery amps condition. whats your driving pattern - long runs or short trips?

Hi Rob, it does a mixture of either a 20 mile or 30 mile commute 5 days a week, the 30 mile commute involves 20 miles of motorway.

Cheers, Martin

ok just wondering as short trips will not keep a battery fully charged, 20 - 30 miles is plenty for that.

Found it I hope! Battery voltage dropped to 9V while cranking so there is certainly a duff cell! I measured the voltage with a calibrated meter directly across the battery terminals rather than rely on the dash voltmeter.The alternator picks it up to a fraction under 14V so no problems there.

    • 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.
