Prius Classic

Welcome first time poster. What country is UAR?

Without the diagnostic trouble codes (which perhaps your Toyota shop can obtain?) it would be hard to pin down the warning lights you see. Usually recommended are cleaing the throttle butterfly, consider replacing spark plugs, and consider replacing the hybrid vehicle ECU with a newer version.

If it has ever previously received contaminated fuel (which is ipossible to know) A bottle of high-quality fuel injector cleaner might be helful.

For the following we need to be sure that your Prius has NHW11 prismatic cells in the HV battery, as opposed to the NHW10 cylindrical cells. Perhaps I overstate the possibility that it might have cylindrical, but of you could remove the lining material from the trunk (boot) and photograph the HV battery aseembly itself? The point is that the cylindrical cells were much more likely to wear out and show the turtle.

Otherwise as far as replacing the HV battery, there is no typical lifespan. It is not desireable that you see the turle a lot, but it does not necessarily mean that your HV battery will soon fail.

The 12 volt battery should be about 28 amp-hours. Weakness there can lead to unexpected fault reports, so it would be good to confirm that yours shows a adequately high voltage, and that all its connections are free of corrosion. The original battery comes with a vent tube, and direct replacements (other than from Toyota) with this feature are relatively rare. In a pinch, I wouldn't mind if you used an unvented battery. Some others are more strict on this matter.

I understand that you want different wheels? of the same size? A direct replacement steel wheel is on the Toyota Corolla, from about 2000-2004. That date range may not be exactly correct.

As your experience with the car grows, you can tell us more about the circumstances under which you see the warning lights. With a newly acquired used vehicle, please change the engine oil and filter, and the engine air filter unless you know they have been done very recently.

 

That's an ORIGINAL model, not a CLASSIC.

The clue from the photo is the fact that the Multi-Display has buttons underneath it, since touch-sensitive wasn't introduced the upgrade.

In other words, it is indeed a NHW10 with cylindrical cells.

Thanks for clarifying Karachi. If any of the wheel speed sensors is not reporting data, the ABS light must show. The magic button in the trunk controls a recharger for the HV (288 v) battery from the 12 volt or additional 12 v batteries. Only the NHW10 has this.

As it's now clear that yours is NHW10, I must inform that those batteries failure rate is areal issue. The individual cylindrical cell is D sized 6.5 amp hour NiMH, so it is not beyond hope to replace them from other sources. However they are spot-welded together and all those ocmplications.

Among the yahoo groups there is Mk1_Prius, which probably brings together the largest internet community of NHW10 owners and watchers. They may have further advice about your situation.

km/L seems like an odd unit until you realise that this has to be a Japanese grey-market export - NHW10 wasn't sold outside Japan. There are some around in the UK as some owners imported them from Japan (right-hand drive, of course). There are some classifieds on eBay with a surprising value still attached - £2,800 for a 1998 with 60,000 miles! Someone's even asking £5,000 for a 1998, although it only has 43,000 miles.

To be honest I'd be inclined to think that unless conditions were pretty much perfect, the fuel consumption calculation is inaccurate. My car reads 2-3% high compared to what my own calculations reckon.
