I can across a couple in Iowa. The lady's bike was completely dead. No lights, would not do anything. They called HOG they could not get anyone to come out. I asked did you check fuses he said no. I pulled out the main fuse and it was ok. Put it back in and it must of rebooted the computer. Ran all the lights came on, ran. Off they went. Lucky

[@rodgough4581]

Great info. Also on ECM updates on your computer, they do not check automatically (dumb), cost 65 bucks each time WELL WORTH IT!! My bike and a buddies were checked for us by awesome McDermotts HD, Lake George, both bikes missing multiple updates, after which both bikes ran incredibly better!! Ride safe.

Thank you for your video! It looks like he will save my life. Can I do this on my Fortye-Eight 2017? The same process you used in yours? On my panel, the engine problem indication light turned on. I went to do the check, it indicated that the ECM failed. I corrected it, but the light turned on again. I believe I will need to do this reboot in mine. Thanks!!!

Just bought a new low rider s and hopefully it’ll get updated along with all the other stuff they’re doing in the shop. I wonder how often these updates are done? Hopefully not too often like Apple for instance, which are about every month or two.

[@RoadRushNation]

They don’t occur that often. Thank goodness. You have to ask your dealer to perform them since many don’t do them automatically. This can be due to customers using other tuners and it can mess with that tune. So just ask your service manager. Ride safe my friend

Thanks for the tip! Subscribed. What caused the issue on your 2021? About to take my first long trip.

[@RoadRushNation]

Thanks for subscribing and welcome to the nation. It’s was an issue where the throttle body has a sensor that loses what speed the bike is and the ecm shuts off the bike. Just make sure your dealer has done all the rest updates to the ecm and you won’t have an issue. Harley did the update last summer. Ride safe my friend

[@tomjones4093]

You can also put your bike into the diagnostic mode and just clear the codes (lots of KZbin videos on this trick). Another way is to pull the main fuse out for about 5 minutes, and it too will reset your ECM fault codes.

[@RoadRushNation]

Yes there’s many who show you how to clear codes. Bad thing about that is if you take it to the dealer now they have no codes to diagnose what happened and what is needed. This is much easier than pulling a fuse. Ride safe my friend

[@-MrRichBiker1967]

Correct for a Dyna or a bagger. Not a softail

Don't know anything about a Softail, but I'm thinking the video I watched from Doc Harley said ECMs all clear the same way. Could be wrong... don't know @@-MrRichBiker1967

Even if you just wanting to do this to your bike just to do it to update the ecm will it hurt doing this anyways to my bike or do I have to wait for their to be a problem with my bike

[@trueman1326]

Will it erase the prior Dyno Tuning after you do this reset procedure ?

[@RoadRushNation]

No this will not impact tunes. Ride safe my friend

[@user-qz4do2qq6e]

There is an easier way to reset the ECM and find the fault code that caused the problem 1) with the bike off push and hold the trigger switch top back left switch control above left grip. Turn on bike it will show diagnostic in display push /release switch it will show fault code. Check website for code if not important ( low tire pressure) push and hold switch until it reads clear. All done.

[@RoadRushNation]

That clears the codes which you don’t want to do if you’re taking it to a dealer. If the code has an H behind it. That means it’s history and the bike isn’t currently having the issue. If there is a C behind the code it means it’s a current issue. If you clear the codes a mechanic has no idea what is happening with your bike. This doesn’t reset the ecm just the service codes.

Does anyone know if doing this will mess with your Dyno Jet tune? We installed a cam and did a tune through DynoJet but I do not have a module attached to the bike. I bought a DynoJet license for the bike and my mech did everything with his equipment. If I do this, will it erase the tune that's in the bike? I'm new to Harleys. Well, new to new Harleys.

[@RoadRushNation]

No it won’t erase the tune. It just resets the TBM back to center to start your bike. It’s doesn’t wipe out the eco

Here's the process...I'll keep you posted.. Harley ECM Password Learn Procedure When installing a new ignition or ECM on a security-equipped Harley there is a "Password Learn" procedure that must be performed. This applies to all Twin Cam and V-Rod models with factory security but may also apply to Twin Cam's with EFI. The TSM/TSSM and ECM have "learned" passwords that synchronize the control module with several other components. Once you remove a component from this chain the module shuts down and won't start. This is reported to only occur with EFI models but the new 2004 carbureted models demonstrate the same shut-down when changing the ignition module.

The engine will cough once in an effort to start but will fail when the module shuts off the fuel74% off the fuel. Special Note: During the Password Learning procedure the ignition will remain in the "On" position for an extended period of time (30+ minutes). While "On", power is supplied to the headlight thus draining the battery. If the battery charge drops below a certain level during the Password Learn procedure the process will cease and you will have to start over. To avoid this connect a trickle charger to the battery throughout the procedure. Download the Password Learn procedure in PDF for printing. Step Action Confirmation Notes 1 Set Run switch to Run 2 Turn Ignition key On-Off-On-Off-On-Off-On and then toggle the Left Turn Signal switch twice. 3 Turn Ignition key Off-On Verify the Check Engine lamp and Security Lamp illuminate briefly and then turn off. Security lamp will not illuminate on non-security (TSM) Twin Cam models. 4 Attempt normal start one time. Engine starts and stalls immediately. check engine lamp stays on. Password has not been learned and sets trouble code P1009, thus stopping fuel flow. 5 Wait 10 seconds Security Lamp remains lit for V-Rod and TC88 with TSSM. Lamp will not be on for TC88 TSM models. ECM enters Password Learning mode for 10 minutes. Do Not cycle the ignition or disrupt power. 6 Wait until Security Lamp turns off or a minimum of 10 minutes has passed. 7 Quickly (within 2 seconds) turn Ignition key OFF-ON Security Lamp remains lit for V-Rod and TC88 with TSSM. Lamp will not be on for TC88 TSM models. 8 Wait until Security Lamp turns off or a minimum of 10 minutes has passed. Password Learning mode for 10 minutes. Do Not cycle the ignition or disrupt power. 9 Quickly (within 2 seconds) turn Ignition key OFF-ON Security Lamp remains lit for V-Rod and TC88 with TSSM. Lamp will not be on for TC88 TSM models. 10 Wait until Security Lamp turns off or a minimum of 10 minutes has passed. Password Learning mode for 10 minutes. Do Not cycle the ignition or disrupt power. 11 Quickly (within 2 seconds) turn Ignition key OFF-ON Security Lamp light and then turn off. Lamp will not be on for TC88 TSM models. 12 Turn Ignition switch OFF. Wait 15 seconds. Turn Ignition switch ON and start engine to confirm the Password Learn Procedure is successful. Engine will start and remain running. If engine immediately stalls and fails to restart the procedure was not successful. Start over at step 1. The above steps must be timed and performed exactly as described. Anv deviation will require vou to start again from step 1.

If you want to check codes what you need to do is have the kill switch on then push in the trip reset button hold it in while turning the ignition switch to on. Then copy any codes that will show and you can then look them up

That process resets the TGS to "0" - See: TT380A- October 16, 2008 - High Idle Complaints on 2008 Touring Models and later. "It is a necessary procedure anytime you replace ECM, TGS or Reflash the calibration to cycle the Ignition switch 4 times, waiting 10 full seconds after keying off between cycles, to relearn zero TGS position. Failure to do this may result in decreased throttle sensitivity." One way to avoid this is to allow the Motorcycle to go to a complete idle prior to turning it off on 2008 and later Models.

You don’t clear the codes. That’s different than resetting the ecm. This doesn’t clear the codes. The codes will be there for the tech to read and see why the ecm had an issue.

Does Harley Davidson have a permanent solution to fixing that problem that gurontee your bike won't shut off. If not then screaming eagle needs to make one that stays in the on position when you are in traffic and is guronteed never to cut off the ignition.
