John Deere uses "Service Advisor" software on computers to hook up to their engines. It is provided to all Deere service centers. It can be purchased by others for a fee. It is not sold. To use it, it must be leased from Deere. You are given an ID to sign in and do your own diag., tests and cals. You are not allowed to reprogram the ECU. For that matter, dealers must get a download from Deere each time they have to flash an ECU. It is done by engine serial number. If you don't pay for it every year, you lose access to it. They don't allow anyone to make changes to fuel, emissions, outside of their group.
Any idea of the fees?
You are describing the factory tool - the same functions given as are given to the auto community. Mods to systems are never supported by the factory tools. Mods are rarely supported by factory design. Emissions mods will never be supported as the OE would be seriously fined by the governments for such.
As I wrote earlier, even the tuning guys who are in the business of boosting engine performance are coming under scrutiny by governments for their mods violating pollution standards. Not sure what will happen to the "tuners" as their business model is being attacked.
Owners finding a way to do emission equipment deletes likely can only be caught if there is emission inspections of the machines required. Else, who could know?
Those wanting to repair - again the real idea behind this thread - should be able to repair their own machine. The best move here is to get the manufacturers to standardize on an interconnection method for diagnostics and to provide access to their factory tool online at an affordable and reasonable cost such that the equipment owner can repair his machine.
How can the community get the attention of the OE to provide such affordable access? That is the question.
We know the OE will cite problems for the OE in providing access:
- they do not wish to support untrained users in the use of their tools
- they will find support of the users while fixing their machines expensive owing to lack of training
- they may have a sizeable investment to make to enable the web hosted diagnostic software
- they will fear that they are giving up information to their competitors who could buy their tool and analyze their technology
- they will fear that the service bays at their dealerships will loose business
- they will fear that providing a standard interface connection will compromise what they can do with their diagnostic methods and communications.
These and other barriers will need to be addressed.. The OE must see a benefit for them as well as a benefit to their customer. How can that be shown?
Those that see "Right to Repair" as a right to modify, that will not be supported by any OE or government official. There too many legal problems with that. The right to repair the machine purchased, that will have traction if those seeking that help cite what was done in the auto industry. The precedent exists. My suggestion is build upon that precedent.
