It is usually 100000klms . But they don't clean injectors these days. They remove/replace the nozzles, test them and reinstall. I'm pretty sure your type has to be programmed or calibrated somehow via a computer. I You don't have to get it done at Toyota anymore, any large diesel fuel injection workshop should have the software.

Thanks roscoFJ73 for the info. I am going to have a diagnostic check of my fuel system to determine if there are any issues. At $150.00 it's cheap compared to replacing injectors at $500 each times 8 plus fitting. Even the pump is well over $1,000 plus fitting makes the maintenance an expensive operation.
