Thanks! So, I should buy the EU verion of ECM probably. I think it will be pain in the ass to bypass HISS, CARB and PAIR systems at the same time
But $200 for US vs $500 for EU ECM makes me cry.
Called EU honda today. They said that it could be the mechanical malfunction too. They can`t diagnose "by photo". So I plan to check the clutch, clutch relay, the
swash plate motor, angle sensor and the HFT free turn too. Just to be sure.
But I still don`t understand how it`s possible could be related.
Step-by-step:
Bike stopped on highway. Spark plug melted, rear injector dirty (error code checked). Does not hold idle.
NO SIGN OF BLINKING "-".
In garage (disassembly):
Still NO SIGN OF BLINKING "-". removed gas tank, removed ECM, removed air filter housing, removed injector, cleaned injector. Cleaned IACV.
In garage (assembly): Installed injector, air filter housing, ECM, gas tank.
And now "-" blinking.
The only possible reasons I can see: before disconnecting ECM, I surely switched off ignition, but did not diconnect the battery. It SOMEHOW caused some short circuit or so, and SOME electric (or electro-mechanic) part died.
TCM replaced, so it`s not it.
Reasons for ECM: 1) it was disturbed while injector cleaning.
2) The
third party motorcycle diagnostic tool could not connect to ECM with first try. Sometimes it needed about 50 tries to connect. And it could
not read the DN-specific sensors information.
Reasons against ECM: 1) Engine is working perfectly. All lights (N, oil, ABS etc) come on and off when it needed to. And ECM can detect errors if I try to disconnect ome sensor
2) The blinking "-" is related to HFT (TCM) but not to ECM. To ECM related "check engine"
MIL blinking.
Reasons for n/d clutch (or it`s relay or swash plate control motor/sensor etc): 1) Can`t shift N/D
2) It is mechanical, so may be no error code.
Reasons against n/d clutch (or it`s relay or swash plate control motor/sensor etc): 1) It was not disturbed. 2) For some problems there is error code exists.
