I apologize for contributing to the thread drift, but the main purpose of electronics on heavy equipment is planned in obsolescence. Much of the complexity is not needed for safe and environmentally clean operation. Complexity often has a motive and in this case the primary motive is to give the banker/manufacturer/dealer more control over their customers, not to give customers more control over their purchases. They seem to want to have every customer financing every piece of equipment for X number of years after which it becomes no longer feasible to keep it in operation (as soon as it's paid off).
It isn't analytical genius that enables mechanics to solve electronic problems on machinery, it is memorized knowledge, memorized information, memorized procedures which in many cases are not accessible to mechanics outside of dealerships. Analytical process and logic stops at sealed modules, unless you are one of the very small percentage of techs who grinds the epoxy off the module and tests the diodes and capacitors etc to trace down the mysterious circuitry.
