Bcm replaced in 18 at 42k miles
42.1k miles bike basically has a disco party on the dash but still runs. Dealership says now it's the speedo so I replaced that.
60k miles bike shuts off again randomly and won't start. Has weird code (pictured below) was on dash and wouldn't restart. Dealer says ecu this time. Replaced it, 2nd time riding it my daughter's vest popped the zipper on hwy, go to pull over and hit hazards and bike dies. Disconnected battery power for 5 min reconnect and bike comes back on. 2 days later we are riding again and this time red light on dash comes on and bike dies for half a second and comes back on. Did this 5 times and then died and started flashed on the dash again. This time battery disconnect worked once and then bike did red light again and died for good. Messed with it for hours, ended up throwing a new battery in and bike fired and got home. Upon inspection of bcm is it very loosely mounted. Enough to where rock shield and bcm are rubbing on each other and wearing on it. It's also extremely loose in the bracketry. Alot of schematics and exploded views show security and abs (I have neither) but the bcm literally slaps back and forth 1/8 in bracketery. Don't see any cracked or bad wires. Connectors look decent. I think dealer put wrong bcm in from start. See pic below for what they put in.

 

 

Weird code, just prior to ecu replacement.

 

Sadly, it's a little late to save this one. It's cheaper to cut your losses and to start over.

 

That is the correct BCM for your bike in 2018... now they are using the updated part #41000348F for the non-security bikes and the #41000349F for the bikes with security.

Did the dealer do and inspection/diagnostic on your bike and then do the work for each part replacement, or did you install various parts "the dealership" suggested..???

If it was a suggestion from the "dealership", who exactly were you talking to? Were you speaking with a tech who did a diagnostic check on your bike (often good advice), a service writer (often clueless), a salesman (mostly clueless), a parts guy (trying to sell a part), or the kid who washes the bikes after service (expert at putting swirl marks in paint)....???

Anything is possible, but just seems strange to me that in the course of 3 years, after 5 years of good service, a bike needed a BCM, a speedo, and an ECM.... Most bikes won't need any one of those in a lifetime and yours needed all three...??? It sounds like "the dealership" is just throwing parts at the problem instead of correctly identifying the true issue.

If the Dealership actually did an inspection and full diagnostic of your bike before each part was replaced, I would at least be looking for a new dealership.... Even if they are usually squared away, it never hurts to have a second set of eyes on a problem that you can't seem to pin down/fix...

FWIW... Since you found the BCM loosely mounted, it sounds like the first repair in 2018, was substandard.... I would be suspect of any wires, connectors, or other sensors/modules that the BCM has been "bouncing/vibrating" off of for the last 3 years as you rode, to include maybe the BCM itself... But I would do a proper diagnostic/inspection on any parts, connectors, wires BEFORE replacing them...

Good luck on the repair and please keep us posted to the final outcome...

 

Would F have been the current rev for this part in 2018?

The dealership has always done the diagnostic and then told me what part they wanted to replace. After the BCM was put in, I did less than 200 miles before they next "failure" to the speedo. At that time I told the dealership very clearly in email I wanted them to inspect the bcm and the wiring rather than just keep throwing parts at it, and that they were not authorized to do any other work outside of that scope. I got a call said your bike is done. Went in and got told a new speedo has been installed and that fixed my issue. I said I wanted to talk to the shop manager. The shop manager came out I showed him the email between myself and the service writer and yes he is absolutely clueless and said who authorized you to do this work. He promptly puffed up his chest and said I don't listen to youtube mechanics this is what the diagnostic said is wrong, your bike is fixed so why are you complaining.
I'm 36 and have owned an HD since I was 18, with a father who has been riding a harley since he was 20, my grandfather who has passed rode his bagger with my grandmother on the back to Colorado in the 60s. We live in WI. We work on our bikes... we customize our bikes... we don't use a dealership unless absolutely necessary. My dad has 120k on his 03 heritage but was smart and went carb rather than efi because QUOTE " I can fix that on the side of the rode, can't fix the electric crap that way" .
After the incident with the shop manager about my speedo I told them I would never return to this dealership again and I haven't bought an oil filter from them or anything since then. Fast forward to this year, jump on my local interstate start leaving and the bike shuts off maybe a mile down the road on the hwy. I can literally see the dealership across the hwy. I wanted to call a truck and trailer myself and take it to a new dealership, after dodging semis for 15 minutes trying to find someone to go get my truck and trailer without any luck I said screw it, had the dealership come get me. Thats where the 5. 0 picture comes from was the side of the hwy. They pick me up, I said thanks for getting me off the hwy how much do I owe you I'll be back from my bike as soon as I get a ride to my truck and trailer. Mind you same idiot service writer. He said well why would you take it, I said I told you I wouldn't **** on this dealership if it was giving away a free bike. He said well we have a new shop manager. So? New shop manager come out I told him the whole story, how I had been insulted by the last one and how I felt about the dealership as a whole. He basically told me, he would check into the things I said was wrong since 2018 for free, and see if what was wrong this time had anything to do with that. Reluctantly knowing this was more electrical crap I couldn't fix on the side of the road I accepted. I also have a PV2 tuner mounted to my bars and on that day it kept telling me when I would try to run diagnostic check it didn't think the bike was on no communication with ecm. I also made it very clear to the service writer and shop manager that I know my pv2 is married to the ecu and that if they didn't have the capabilities to work with it don't bother. He assured me they did. A week later I get told the ecu **** the bed. I again said if you can't remarry my tuner do not do the work, I would pay for the tow, diagnostic, and ecu but would take my bike to a shop that could do exactly what I wanted, again was told they could do the work. Reluctantly said fine. Got rhe bike back, tuner wasn't remarried, and I was pissed. Wrote the owner of the dealership an email detailing my last 3 years of Sodomy from his dealership and have yet to receive a response. 2 days later I hit the hazards and bike started going nuts again. This time I called corporate HD, told them my story and that I wouldn't trust a dealership to do any work again until I saw the parts myself. I have a shop manual (not electric diagnostic) just the mechanical. And here we are today holiday weekend and I have most of the rear end removed from my bike trying to find a broken wire or ground and that's where I am now, the current bcm bounces around in the mounting plastic and has a wear mark where it has been rubbing the rock shield and plastic mounting bracket. My daughter just finished the riding academy at a different dealership 100 miles away and I showed him the rubbing and a video of what happened the last time the bike shut off (daughter taped over my shoulder as it was dying) new dealership said it looks like the tip over sensor is shutting the bike off that is inside the bcm. My bike doesn't have a security system nor abs brakes. But both of those modules also connect to this bcm mounting bracket. I don't know if those voids need to be filled with something to make it not fit sloppy or if that bracket is just so far out of whack that I need to replace that and the bcm again but it's very frustrating. I am hoping corporate HD will stand up for a guy who's family has been riding these since the 60s and dealt with the AMF years and still rides them but I sure hope so. Any other suggestions would be greatly appreciated though since it's a holiday and no one is open.

Sorry for your experience with that the dealer... unfortunately, there are too many stories such as yours, part of the reason I rarely let a dealer do anything to one of my bikes... the dealer arrogance is reinforced by an army of clientele who know nothing, and trust in anything the dealer says to fix their bikes...


FWIW....

The dealer should have known, if they have any experience at all, that once they replaced the ECM, they WOULD NOT be able to remarry any tuner to a new ECM, without the purchase of another license from the tuner company... For your PowerVision tuner, just like if you were adding another bike to your PV tuner, contact DynoJet, buy an additional license for your tuner at the cost of $199.00, then you can have your tuner married to your new ECM...

As for your BCM installed in 2018... I believe they probably used the current one for that time. The updated parts, as long as they have the same part number but different suffix letter, are mostly the same. The newer letter could signify anything from a running production change/upgrade to the part, to just a supplier change... The part number that they used was for a non-security bike...

There were many bikes without the security alarm or ABS and I don't believe for a second that they were shipped with a loose BCM in the bracket. I suspect something is wrong/damaged with the bracket... the parts fiche doesn't show a separate bracket between the two BCM numbers. It shows just a BCM, ECM, and then the security siren module (where applicable) in that bracket.. I suspect it was a bad install, that either led to wear/failure of the bracket or maybe the non-security BCM gets shipped with some kind of shim to allow for it to fit properly in the bracket. It is possible the bracket is still salvageable...

I believe it's possible, that the tip over sensor could be causing your problems.. There was a thread on here not long ago, where a guy couldn't get his bike to to start, and it was a broken bracket on his TSM that caused it to fall over on it's side, and the tip over sensor couldn't obviously be reset... That was with the TSSM/TSM module configurations...

I believe, that when the BCMs came into play, they took the place of the TSSM/TSM modules... I did notice there were two BSM part numbers for your bike... one for non-security and one for security... just like the TSM/TSSM modules of old...... So it stands to reason that the tip over sensor, is now part of the BCM... The old TSM/TSSM would display a message in the speedo, "tip", when the tip over sensor was tripped... maybe the BCMs show a different message/code like your "5 0" message...

Good luck with the fix, I would only suggest that if you are going to let the same dealer, new service manager, fix your bike... try to control your emotions.. Stay focused on the details, be firm on your directions, yet be polite and civil...

Please report back the results...

 

I am sorry that you have been going through this for years.

hattitude has you covered. I only have two comments:
1. You won't hear back from the dealership's owner. As far as they are concerned there is nothing to gain from communicating with a disgruntled customer. They would rather you go away.
2. The MoCo doesn't give a rat's *** that your family has owned Harleys for generations

 

The same dealership will never touch my bike again. I am thinking the same about a shim or something that should have been in there to make it not bounce around like that. I will have to wait until tomorrow when I can talk with the new dealership and show them the bracket and how the bcm rides in there. Thanks for the input, and explanation or parts.

One last question, do I have to use a dealership if in fact I do need to or end up replacing the bcm?

Also luckily PV isn't forcing me to buy a new license since I was able to prove I paid for a new ecm. They are going to send me something to remarry it myself. Their customer service has been great..

 

Good news about DyoJet giving you a free license to re-marry your PV to your bike... good to hear about good customer service...

Any online vendor can get you a new BCM, but it usually takes a week or so, because most drop ship the parts from the MoCo...
