Appendix: if you got here because you've no keys that can make the transponder ECU work, instead of removing the system, find a better locksmith familiar with transponder chips and their documented flaws.

So after all that, if your 1996 diesel is cranking but refusing to start, it's almost certainly the transponder immobiliser either not reading the chip or some power gremlin to that system. If the solenoid was then revealed by removing this Bosch cover, one would still need to think how to...

Salvage units appear to have some circuit under this cover. I'm betting the signal from the transponder computer is binary to this item, which then decides to pass voltage to the solenoid it is hiding. Otherwise you'd just be able to tap one of the three wires to get it to start which would make...

They look to be just an armour cover that looks conductive, and not a fuel solenoid itself Bosch Steuergerät Magnetventil 0281005002 , 9947151 , 0 281 005 002 | eBay - [Leaving Land Cruiser Club]

These Bosch units seem to be called a similar thing 'BOSCH ANTI-THEFT SOLENOID CONTROL VALVE' https://dieselpartsdirect.co.uk/bosch-anti-theft-solenoid-control-valve-0281005046-genuine-unit.html So is it just a dumb voltage wire to a solenoid or what?

So fairly sure it's to do with T22 Transponder Key Computer via Pin 10. Pin 11 to the ECU appears to only apply to Petrols (*12). And the only input the fuel cut valve gets (which I think is the name for the armoured thing) comes from the Transponder.

Yup, appears so. Here is the Toyota GB guide on how to fit TVSS. TOYOTA TVSS IIIB INSTALLATION INSTRUCTIONS MANUAL Pdf Download - [Leaving Land Cruiser Club] 2 and 5 are on by default, which relates to (via a Celica manual...

Putting this down to a hot engine, without the exhaust manifold heat shield fitted, warming up the vacuum sensors / lines immediately above it, to the point they started to read funny. This code indicates an issue with a system that may no longer have any impact on my particular vehicle, so if...

All credit to this chap for uploading the Toyota document, which I duplicate here incase of future dead links. gilmorneau - [Leaving Land Cruiser Club] My code was 71 aka EGR bits.

I think the glow indicator is trying to tell me something else. I'll see if I can read the code, should still be stored (codes on an 80?! ) De-smogging a FT - injection pump question - [Leaving Land Cruiser Club]

As there was no performance impact, I presume not? I would guess 600W of heater into the intake would have been noticeable especially as the engine was already loaded, and I recall the dash voltage meter being at its usual position. Frustratingly it is intermittent and I am unsure how to...

Had the glow plug light come on for the first time ever, in 14 years, and whilst driving. Stayed on. Toggling the ignition a few times when parked eventually made it disappear after a fuel stop. My understanding is that the glow screen runs on a timer influenced by the coolant temp, and it...

I have a late model 80 with factory TVSS alarm immobiliser. I recently needed to troubleshoot the fuel cut solenoid, but found that I couldn't see it as it was under a cover. I suspect this is a physical protection for the immobiliser function. (edit: immobiliser is factory and separate to TVSS...

I rebuilt mine a few weekends ago. Pretty simple albeit fiddly, you'll need RTV sealant and grease to hand as well as a few fine tools for keeping commutator springs in place, a multimeter, and a nice to have is a bench PSU or 12v battery to test the motor works OK. This pdf Repairing...

Well this is the part that didn't make sense to me either about failure points. And if it did, worst case is that the truck would breathe as it were designed to. Thanks I'll have another read. Such a rabbit hole

Theoretical question time. 1) I've read if you add any type of intercooler to a 1hdft one gets a modest performance increase eg +15hp, even if you don't tune the pump in any way. Like when the truck is cold it goes a bit quicker and is a bit crisper, it stays like that instead of a bit sluggish...

I had the ACSD removed on my HDJ80 due to an air leak allowing fuel to drain back to the tank, preventing a start when parked uphill. After removal it started in London's winter (-3C) but was certainly a bit lumpy at 4-500 rpm and required a bit of throttle or hand idle to bring up to smooth...

Not alone in that regard, unfortunately. I highly recommend a basic google / forum search on any workshop - as well as faith that people are open about their experiences vs being silent just to maintain some kind of working relationship in future.

My take on this is that £12.50 isn't enough. Clearly I'm not going to scrap the FJ80 for £2000, nor does spending let's say 60K on an equivalent vehicle make any sense to avoid an occasional £12.50 charge. So it is not enough of a penalty to invest in avoiding. I genuinely can't think of a ULEZ...

Yup, though that's ~£130 in Australia, but £516 in UK. So that's quite a markup of 4x. And if that was the correct price, on what planet is that a reasonable amount for items that at worst cost less than £100.

As mentioned, the code is used for the insurance to essentially confirm that your licence (and that of the named drivers) is as you have declared it. IE correct number of points etc. Rental companies do this too. The request can be triggered by as little as using a comparison site to 'simulate'...

On the off chance this is useful as a troubleshooting step, my 80's ABS doesn't try to work when the vehicle is moving backwards - and if I recall it's regardless of being in reverse gear or not, implying the sensor/unit can't do the negative maths.

Well... a dirt bike's rear disc is often single skinned so they do overheat... I think the stock rotors on an LC80 are double-skin / vented, but not drilled or slotted, hence my curiosity towards the latter two choices.

I'm curious regarding drilled / slotted rotors. In the dirt bike world people intentionally run solid discs to keep the mud etc out and eating pads - is that not a factor for LC80s?

Thanks @uHu So for an air heater, using Eberspacher S2 D2L as example, 31W at 12V makes 2.6A amps on full chat, with an 'off' drain of 0.34A until it depletes to 10.5V. For 2x100Ah Yuasa, in theory this runs for 200/2.6 = 76.9hrs. But that's not the reality. One could halve battery power in...

Am I correct in thinking that a coolant heater (eg Webasto Thermo Top) would require the cabin fans running via relay, and therefore likely to run down the battery, if used throughout the night e.g. 8 hours?

A blast from the past, but I did 12000 with no ill effects according to an oil analysis: 1HDFT oil change interval and analysis - [Leaving Land Cruiser Club]

I too went down this thought process. My conclusion was to leave the car as it was, and buy a portable power station with built in invertor for the 'house' stuff. Charge that off the car when driving, and use it in the car or around the camp when stopped. An extra battery + wiring + changes to...

I would recommend a bodyshop in London, but that's the wrong side of the Atlantic for you :sweatsmile:

With regret I'm unavailable; certainly seems a fitting send-off.
