I got a 97 Ultra injected and I am getting a check engine light coming on every so often. All my guages are reading OK and the bike is running OK at all times. My question is is there a way to make a test light or jumper wire up to make the ECM/Data link connector&nbsp\\;give up the troble codes that it has stored? The factory&nbsp\\;shop manual I have only gives instructions how to check using either a scanalyzer or diagnostic test lamp that you buy from Harley. I know there are other post s on here on how to do this test on newer bikes&nbsp\\;using a jumper wire and getting the dash light to flash the codes.&nbsp\\;

 

&nbsp\\; on my 1998 road king classic with fuel inj. you can read the codes doing the following:
1-turn ignition key switch to ignition and then turn off 1 second after fuel pump stops.
2.repeat #1 again..remember 1 second after pump stops
3.turn ignition key switch to ignition and wait about 8 seconds for a bunch of flashing of the check engine light
it will then stop for 2 seconds..get ready... these are the codes you must count:
it will slowly flash 1,2,3,5....there is NO 4....this is the first digit of the 2 digit code ..so it can only be 1,2,3,5 &nbsp\\; __ __
then a 2 second pause...then you will get second digit of the 2 digit code..it can only be 1,2,3,4,5,6
remember after the complete 2 digit code is given you will go back to the rapid flash sequence..
there are a total of 15 codes available with this procedure
examples
52,53,54,55 bad news ECM replacement
56 crank/cam sensor
11 throttle sensor
12 barometric
23 and 32 are injectors front/rear
24 coil
33 fuel pump relayin this case you would not hear the pump but instead waited 3 seconds after the on / off sequence

in order to erase any codes you must disconnect the battery or wait for 50 on and off riding cycles
