The "green ended" one is the ECU check wire - ground it, turn on the key - get trouble codes. the other is the ALDL (Assembly Line Data Link) connector - this is where the ECU's programme is dumped into the bike on the line - and where the diagnostic tool interfaces with the ECU.

How does it display the codes?  As series of lights flashing, etc?  If so, is there a key chart somewhere that we owners could use for troubleshooting?

Hi,

Is there any way to re-set the blink content of the ECU? It seems the ECU stores all error codes even after everything is working perfectly again?

Thanks

Most ECUs, cars and bikes, you just disconnect the battery for a good 15-20 minutes and that will usually reset the codes.

Thanks!  This will now be squirreled away in my new "Little Book of Enfield Knowledge".

Dan, I printed the codes on a card, laminated it and tucked it into the fuse box.

Not the case with the UCE. It stores the codes until they are erased with the Factory code scanner - which no one has. The ECU will display the codes set from last to first with no repeats. Also a code "41" is USUALLY a rotten ground in the system - NOT a bad injector. It's a pretty common code to come up .....

   I can attest to that !      And as was explained to me ^^^^  Before I hung myself from a rafter with a motorcycle chain !  If you have a sensor disconnected, with key and ignition on.... it will through and store a code.  I did this when rewiring the bike and testing.  ... But even though the code is stored, the MIL light will go out when corrected.  So bear that in mind when trouble shooting.... if you start pulling sensor plugs and such.  Don't get alarmed.... just remember what you pulled and whether the key was on or not.
