Have you had the battery checked for condition and charge as this can cause the systems to go offline

Is the vehicle battery in very good condition and have a full charge?

Have you tested for exhaust leak (air being drawn in before or immediately after the cats? Smallest amount of unregulated air can cause this symptom Measure the oxygen content at the exhaust = should be zero (0) in O2 content Also briefly block the exhaust with a rag and listen for any hissing from the exhaust components

It seems a common fault around the world as long as there is scrap value in the precious metals within the cats. There are stocks of cats in some aftermarket companies and I believe some use different materials to achieve the same catalytic conversion which will help in the long term as no value to theives

Worth checking the wiring as it goes into the tailgate from the body as this can cause breaks in the wires as the tailgate opens and closes and articulates the wiring loom

Battery condition poor, low voltage and setting the alarm off?

It may be worth looking at the wiring loom that comes through from the bulkhead area (A post) into the door as this articulates when the door is opened and closed and could have broken a wire?

I would be looking at the thermostat area as this is what has been recently disturbed Let us know what you find

It may be possible through dealer level programming but not sure there is any other way (insurance purposes I would imagine)

Wow! had to look that one up as never seen one before, looks quite unique Somewhat like the Ford P100 camper of a similar era

Thanks for sharing the information it certainly looks good and not too blinding for oncoming motorists

Hi TimB ...welcome to the Club Let us know when it arrives and look forward to seeing some pics of it Good to have you onboard!

Any more development with this issue?

Hi Mike....welcome to the Club Good to have you onboard

Is the servicing up to date and even tire pressures make a difference to the economy

hi and welcome to the club what an absolutely superb Supra, brings back memories of when cars used to look different and were instantly recognisable when driving past Good luck with servicing and keeping it on the road

Sounds like there is an intake leak from the engine and you are losing vacuum for the brake booster and also engine performance relates to this fault as well

Most manufacturers artificially increased the economy claims by various means and although the vehicles can obtain the higher figure it does take a lot of doing, e.g. at night, with no traffic, less fuel in the tank, no passengers, etc, etc

I would definitely take the car to the Toyota dealership to diagnose as you are dealing with Hydrogen gas which although not necessarily unstable within the fuel cell would still need to be checked to be on the safe side

There were issues with Toyota sourced airbags (from China) which resulted in a massive recall (in Europe) of many vehicles from different manufacturers all using the same sourced airbags. This may have led to difficulty finding the new supply of airbags that hadn't been earmarked for recall Used Airbags (e.g. not deployed or been damaged in accident - so stolen/recovered, etc) are acceptable for re-use in Europe (certainly in the UK) and there are dealers who legally trade in them

Hi Tim Flx ....welcome to the Forums You certainly are an avid Toyota collector and fan of the brand Good to have you onboard!

Hi Pat....welcome to the Forum How is the rebuild going? The ES will probably go on for many more miles as that was a good year for automobile production, I think post 2007 models started to show some issues. Good to have you onboard!

I would remove the thermostat to see if there is an even flow of coolant. If so, then chances are it is a faulty (albeit new) thermostat Air can be very difficult to remove from a cooling system occasionally but always check the obvious things first. A coolant pressure cap is a prime example of when it fails for the pressure to drop and lead to overheating and also a source to introduce air into the system......very cheap part to replace

Sounds like a wheel sensor is sensing some wheel slippage....check tires (tread, pressure) and also that the area where the wheel sensors connections aren't clogged up with dirt, etc.
