Technical Reading Dump for HC11F1FN on IAW16FEK

[Read]

Hello.Friends.
During operation of the engine, bad reaction gas is too rich at idle.
If you try to fault diagnosis, I realized that feedback control of the O2 sensor is not normal.
I tried to replace the O2 sensor, but did not change it.
(., Which had a very painful spending)

After all, it is concluded that failure of the ECU, (connection to the diagnostic equipment've got interrupted!)

I'm decided to repair the ECU.
Reading on the target board of your own is removed from the circuit (Immo data! There is there) the CPU to save a backup of the data.
Here now.
I plan to replace the Xtal with the CPU.

Thanx.

Are you sure it's not just the catalyst failing? Much more likely, I would have thought, than the ECU -- especially if a new lambda sensor hasn't resolved issues....

Hello.
Thank you reply.
The engine is properly output a high load at high rpm.
Idling is stable remains dark mixer. (Exhaust gas I smell)
Such as misfire specific when the catalyst is damaged is not happening.
change the Slow was closed loop in the engine control to the open loop soon.
Considering them, it seems only idling control in such a way have a problem.

And that above all, communication with the diagnostic equipment is interrupted is fatal.
I want you to let the symptoms of when the catalyst, which is a classic you guys is damaged.

And it there any effect on the ECVT? ?


I'm sorry story is long.


Thanks.Kind Regards.
