Hasn't done much good. C-5 seems to fall apart after 4 years. Besides the water pump. That goes in the first year.

The **** RST was the protype for the c5.

It was available to customers for 5 years before the c5 went on sale.

Their not that sophisticated yet... I think crown just hasn't gotten its act together on lpg trucks yet. They're still in trial and error phase. You'll need to call crown dealer for program update.

Crown is going the way of tesla.

In the future, if you do your own repairs/don't do enough service call business with crown, then they will retaliate by reducing engine performance, removing functions, stc.

HI GOOD NIGTH I NEED REPROGRAM A CROWN C-5 ECU IF IS POSSIBLE HELP ME WHO DOES THE REPROGRAMMING

Update. Software upload by Crown worked like a charm.

Yes. Thanks for the info and thanks for helping. Will tell the customer to call Crown and will report back.
Thanks again.

Its technically not a recall, the symptoms do not effect every truck in the production date requirements. Not all trucks show those symptom and is not always necessary. Its also effects trucks depending on how the customer is using them, running periods, long idles, and other events. The software is also proprietary I believe and crown wont give it out to just anyone I don't think. They did have a software update on pallet jacks not long ago that was considered a recall. They contacted every customer who was sold one and did the updates for free. Hope it works out for you though.

Thanks. I guess will have to call Crown (sigh).

Gee, love how they call it a service bulletin instead of a recall. This way customer pays for it...

If the truck was built between 11/11 and 11/13 there is a service bulletin for hard start or no start symptoms. The access 3 ECU software must be updated.

I have one doing the same. Did a tune up, regulator, mixer, throttle body all replaced. Was told there is a possible software issue with access 3 and may need upload or replacement. I'll post final if it works. Good luck!!

Any idea?
