No MIL signal on E31 in '05 Accord ECU?

[husseinholland]

I wired the MIL in my cluster to E31, following general wiring diagrams. It doesn't illuminate when I get a code.

E31 is shown as vacant in the Accord schematic



Any suggestions? Someone on K20org said it may be that the MIL is handled via CANbus to the cluster, not the same as RSX.

If that is the case, I may have to get an RSX ECU & swap over the end user board. I need to know the MIL will illuminate when I have a code - I've already had several instances where the car ran erratically/jerky after a idle related code was set.

Any advise?

Found a 37820-PND-A63 - which will work with KTuner according to the list (https://ktuner.com/rsx/)



This way I could also get back reverse lockout which I don't have with the Accord ECU.

Do you sell just the header board connectors so I can fit them to the motherboard? I've solder zif sockets to Volvo ECU's in the past, these look easier to solder than that

Accord does not use E31 for MIL.

I have discovered that. The question is, is it handled by another ECU pin?

If the answer is no, can I buy the header board sockets from you so I can transfer my user board to the '05 RSX ECU? If the answer is yes, can you link me to the product?

Dealers sell prepped ECUs if you need one. You'll need to unlock your unit prior.

I don't need a prepped ECU, just the sockets so I can transfer my board.

Just to close this Xenocron will socket the RSX ECU for me.

That also works!
