I have a troop carrier HZJ78R(2002 model) and the timing belt warning light came on at 120000km's. I want to reset it but have been unable. I got some notes from this forum about changing them on a UXJ100 and HZJ105. While it seems to make sense it does not work on my truck and I am thinking that either the notes about changing do not relate to my vehicle or there is some missing information. Can anybody help me with this little problem?
Thanks

wouldnt be a bad idea to change it - but that wasnt the quistion, Have a look at your speedo and there should be the knob sticking out to reset your odo. near that there is a rubber grommet. Remove gromet and using something thin and long (no no not that!!! maybe a knitting needle) try pushing the button you can see through the hole. (I have never actually done this so am unsure if it is a button or actually something that needs turning)

Thanks Davoe, the timing belt is easy to change but the light is not quite so easy... sigh!
My last truck(75 series) did have the grommet but this one does not and has a LCD Odometer. Any other ideas???

It seems strange that your timing belt warning light came on at 120000 kms. for a 2002 troopy as the book says change at 150000.Hope you din't buy it second hand and the odometer has been tampered with.

Thanks Rambler,
This was my thinking exactly about the change time and I did buy it second hand. But there must be someone who knows how to change this bloody thing.
see ya

Yeah mine came on at 110k instead of 150k (I presume it was supposed to be 150k) and the car had 45k on it when it was imported so I can only assume it had 40k wound off it. No biggy really, means I've done 150k instead of 110k. Still worth the $10k saving on comparable models and being diesel it's really stuff all.

Mine had the gromit, just pushed in and presto. Mine also came on at night and it scared the begesus outta me. Driving along and notice bright orange light on the dash that's not normally there!! ARRG, oh ok.
And just for a point of refference I had the belt changed by Toyota 10k previous, good to know are following all the procedures.... It has also been done by a Toyota dealer here in Perth at 50k.......

As posted remove grommet, push down and presto. Mine came on while I was driving at night...most distracting.

Footloose,

2002 has the electronic speedo - no grommet.

Hearpro,

My vehicle is an Oct 2002 Build, has the electronic speedo with the two tripmeters etc, and should be identical to yours.

It was probably me who posted the method you've seen for the 100series.

I've used exactly that method on my vehicle and it works (but I didn't do the whole lot, as I've only done 80k). But it took me a few goes to get it to happen. I think it times you out.

I think you just need to try it again, until it happens.

If the light has come on at 120k, its likely that someone has already played with the timing light reset and stuffed it up. Because when you use it, you set how many k's you want the light to come on again.

The method is also posted in the files section on 70scool. If you still have hassles, theres a number of people there with the more recent 78/79series, but probably not a lot have required a timing belt change yet.

If it doesn't work, I'll do it again on my vehicle, and see if theres anything I can suggest. These warning lights are a PITA :-)))

Cheers
Phil

Have a play hearpro and if you cant get it just email me at lonards@bigpond.net.au and I can fax a copy of Toyotas reset programming to you on Monday morning. I won't be back at the workshop until Monday.
I am pretty sure I posted it on this site.
I will do a search.
