Let's more have a discussion on the 3-D's: Dependable/Durable/Dead.
Dependable: You have to agree this is a killer of a bike right out of the crate. No mechanical/electrical/engineering flaw you can point to. That was since the day you owned it. A car on two wheels. Component wise, how many miles are on the car you have? And you are going to change out what?
Durable: It has the same durability as a car component. Whereas, we are discussing the fix it before it breaks v. let it code to tell you. That's the discussion. We are riding a backup-coded bike that gets you home. Knowing that, and say there are 9 running backups to keep running, here is where you change it for argument sake.
What I'm thinking is to know the electrical side of self diagnosing. This way you do not waste your money, the parts are not tampered with. It's a closed loop system in many ways. When it codes it breaks that loop. That's when you inspect for a dropped analog signal at the jobber, and now the ECU duplicates it in a backup. This is now a digital action and the ECU takes over for the analog.
No pun intended, but the key here is key on. That says a clean code-less jobber that is not out of spec. You now think, the jobber WAS sending thousands of signals [analog] a second, but now the jobber is ...
... Dead: The jobber is sending no signal at all [one single digit] and that reads as 0 to the ECU. Thousands of times is the discharge of one saved value. It knows if the rpm/wheels have moved a wrinkle at every fill of that ever changing [analog] signal. But it keeps sending in 0 after the same [digit] of 0 in binary speak. The dash sends in a code number that points to that jobber. Therefore, it's so simple in its complexity, your wife has to know this so she's not snowed at the service drive once the check-engine-light comes on.
I believe this is how the abstract in the service manual is explaining it. They expect you to understand the motherboard parts as to how the jobber fails. So D stands for Digit and that same 000000000 is D E A D on arrival. You may now spend that money on oil and filter changes. Clean is the machine.
Fuel pump wise, I too am guilty of hording parts I may never use. Again, key on is going to make a sound or not. And on its last breath diagnostic wise, it's a get you homer, but if you give it gas it falls on its nose. That's my campfire on this side of the lake, fix it when it breaks.
Signed,
My self diagnosing ride that still gets me home.
