Steering controller failed after 12 months cost €3400
Ram snapped
Lift height measuring system very bad design, so easily damaged
Accel pedal badly designed, dirt building up under pedal and causing faults
Cold store application disaster
Latest on truck only 18 months old and controller crapped out
One went down under warranty took Toyota engineers (3 of them 1 month to diagnose and repair)

Just a sample. Bad design bad back up. In my book that equals troublesome.

8 series 3 wheel c/balance 2 months old went down, Toyota took it back and just returned it after a 2 month repair in their workshop. Oh yes brilliant machines, Not!!

I've been looking after RRE's since they first came out back in 2009, yes the early ones had a few issues but BT soon fixed those & rectified the earlier effected machines.

I can't except there troublesome machines as I have several customers with RRE's of different ages, configurations & sizes, some have nearly 20k hours on & its very rare to get one in the workshop for a breakdown.

Have a customer with a fleet of RREs and a few 8 series counterbalance just to make it even worse. The RREs are very troublesome machines compared to the older 5 and 6 series and other brands. Dealer technical knowledge is poor and response time to trucks under warranty outrageously bad.
I've helped one of the head tech guys in Europe numerous times with technical issues on other brands and when I look for support they usually have to go back to R&D group for answers which doesn't inspire much confidence.

Thanks Forkingabout as usual that's all good info.
I'll chat with the dealer tech guys and see if they are aware of TSB's etc. being on their tablets, and try and encourage them to send feedback to BT if they are not doing so. Hard for BT to address a problem if they don't know about it.

TSB are uploaded to the BT Toyota online portal & any BT Toyota technician should have instant access to it anywhere in the world via there BT Toyota issued laptop / tablet.
There also held on the device memory IF the technician remembers to update it for offline working.

As for tech support, here in the UK where I'm based, we have UK tech support that we can contact if required but if its something that they haven't seen or it needs feeding back to the factory then they would contact tech support in Sweden.

As for product training, in the UK the RRE is a core truck & the training for it is given when you join the company in a service position - its a 2 day course just on the RRE.

Oh - I'm sure there's going to be a warranty claim. This problem tied up 4 different dealer techs for the better part of a week. Between the wrongly placed cable on one unit and code 4:195 ( on all 3 new units)which finally went away after a complete mast re-calibrate.
These techs are claiming that they have absolutely NO contacts at BT/Toyota that they can reach out to for tech support?? If true I find that absurd. I know at least this dealer, does not sell many of these machines , and I'm led to believe that there are not that many sold in all of Canada.
I have NEVER seen a TSB (technical service bulletin) in their hands and the training they received is years old and not really applicable/relevant anymore.
The salesmen of course would never admit this is so, but I feel they don't think the training is warranted given the small fleet they have out here.
So as an end user we are left with brand new equipment that doesn't work and no where to turn.
It's a little scary.
My only recourse, once off warranty, many times, is this forum, and the good people who bail me out with all their help.
If anyone can shed some light as to why this dealer cannot get tech support (if it exists) I would sure like to here it.
In this day of modern communication methods surely the distance between Sweden and Canada can't be that big a deal.
Your thoughts please.

Make sure the dealer tech feeds that back to the factory - puts a warranty claim in.

New heater - same issue. BUT.... dealer tech discovers heavy cable ( #160 ) that feeds the heater was installed at factory on wrong terminal of the main contactor. Should have been on B+ cable side. Verified by looking at another unit. Moved the cable - coding diarrhea stops. Life is good !!!
Good catch dealer tech !!!

Different "trusted" battery - sadly - same results.
It starts fine with "fan on "only but will not with fan and heat activated. I realize that the toaster grids won't turn on without the fan just saying it's the toaster grids that are causing the grief. And like I say - once the truck starts you can fire up the heat and it works just fine. Have a brand new heater assembly sitting here - techs may install it and see if problem goes away. That will at least fix it or eliminate the heater itself as the culprit.

Battery is brand new like the lift, not that that guarantees it doesn't have a problem. Checked and double checked the fuses, fuse boxes/holders, cables, cable connections everything we can think of. I'm going to switch out the battery today and see if a different battery produces different results.
What you're saying makes sense so will re-check cables etc. once more.

What condition are the batteries in?

A large current draw on the battery ( from the heater ) will upset the CAN systems on the RRE.

I take it you have checked all the cables, connections & fuses for the electrical system?

Have discovered that the series of codes occurs ONLY if you start the truck with BOTH the cabin heat and cabin fan in the on position. If you shut them off, start the truck and then turn the heat and fan on the truck runs fine. Seems the truck doesn't like the extra power draw from having the heater engaged upon start-up OR the heater is screwed??
