Harley-Davidson Problem Codes | What Do They Mean?! | Doc Harley

Thank you Doc, I’m so furious right now, I bought new 23’ RG and ordered stage 1 and new bars for it, parts came in and dropped off bike, days later (late yesterday) went and picked it up & 40 miles later, west to take ride to dinner and 3 lights came on and codes are P1100c and C1032c, I have suspicions that the dealership cleared codes to get me to pick up the bike knowing the lights would come on after I left, can that be possible to ride the bike until Tuesday (dealerships closed) with those specific codes showing? Any light shed from you would be great.

Well that don't help any. It tells person to take to shop to get fixed. People need trouble shooting information videos

Ha. My left had switches shorted out and MAN I got alll kinds of codes, think there were 2 ecm and 2 bcm and even abs or speed0..

Might have had trouble figuring it out EXCEPT, I knew I’d previously had to press very hard to get my hi beams to come on … then hard pressing the trip switch made them come on.. hah, was kinna a no brained at that point .
Turned out the wires that go into the glue on the back of the switch were the issue. ..

bike just turned 1 year old P0264 pops up and registration is now expired. FML and Fuck Harley bike has been nothing but fun and issues since I got it.

Code 57

Hey Doc another great video! I’m getting code PPU 82883. What does this mean? Do I need to take to the dealer or can I fix it? I’m not finding a solution on HD forum.

Hey Doc. Thanks for what you do. My wife, a 06 cvo v rod, is having a weird health issue. Battery was doing some weak starts and died a few times. Then Wednesday, charged and strong, ot started fast and ran well to 3 different locations and suddenly barely cranked but did start, went 200' and died with no juice left to crank. Just turned to E but should have made it at least 10 more miles, but so tried jumping, no. Tried with a little fuel, no. Even being jumped by a charger/jump pack, half the time barely cranked and other half cranked strong but no. Now new battery + plenty fuel, no start and even cranks slower immediately AND I don't hear fuel pump at all, plus didn't get fuel from bleeder valve when tryingto start. Did I kill her? I love her and need her back. Voodoo? Black magic? Help please! I have codes.

What does priority order mean

Hey Doc, does my 2019 FLHR have the light for emissions?

I have A P1001 code

Hear is my comment,what does "no rsp"mean

Doc, I replaced a bad ignition switch and now my speedo is completely off but red key light is on... please help. Thanks 👍 (2005 1200xl, w/carburetor)

I thought You were going to tell us what the codes THEMSELVES meant. You just told us how the check engine light works. worthless to Me.

P1511c, and P2135c. 2021 Road glide with just 2K miles on it. This is unacceptable. Had to limp the damn thing home. How embarrassing. Last Harley I ever buy. Voltage regulator went out at 4K miles on my 2020 softail standard I had prior.

Recently my softail Fatboy 2008 comes a bus err and also one of my turn signal does not work right side the error codes shows are u1300 I can't fix this how can I fix this

Yes I agree a process in deed!
I have a 21 Harley 48 and threw a B1211- fuel level sender shorted high side
The dealership already replaced the pump and are going to replace the harness but I told them it's probably the resistor based of the wiring diagram because the pump still works when fuel gets to low than light comes on

Why so they can just sit there replace part after parts at your dime of course bunch of dumb asses

Yeah I got a 2014 limited I’ve always had a pan head Or shovel head I guess I’m just old school I hat my 2014 but I love the ride on 2014

NOT THAT SIMPLE! I just bought a new Screamin Eagle tuner for my Street glide. After spending the money for the tuner and the time to install the tune, now I have to spend more money and obviously at the dealer to have a 02 sensor code removed. Ive had this bike two weeks and Im starting to think this is a mistake. Especially for a bike with 900 miles on it.

Great job Doc, I'm a licensed automotive, marine mechanic and of course play with bikes.. but I know my limits... even after 44 years wrenching.. I literally could of been rich just answering those questions or the client puts the phone near the noise.. absolutely hilarious..
I so have a question if you could answer..
I have a 05 fat boy CVO with 18,000 kilometers on it.. it drives me nuts why my machine seems to idle to high after warm up. It's always idling around 1000. Now that's what the tach reads.. haven't verified with timing gun.. but I really loved that classic lower Harley shuffle that the old carbs did, you lnow the classic of timing of Harleys.. I've verified no vacuum leaks, never touched timing or mods on this prestine factory screaming eagle set up..
Any suggestions or theories??
Thank you for your time..

Great vid, Doc. Thanx

I've took my heritage in for service they told me the wrong oil was in it I told them that you are the ones that serviced it last he wanted to argue with me then I showed him the receipt of the last service Oklahoma city Harley Davidson trying to screw me I have a 2011 heritage

This isn't necessarily diagnostic code-related, but can you do a video on Low Rider S handlebar death wobble and shift linkage loosening where it moves back and forth behind the rear cylinder after a few hundred or a few thousand miles?

Another reason for checkups at dealerships are to update your software

Unless folks are mechanically inclined, and have that picnic table of diagnostic goodies...It's really best off to the dealer for DTC issues.

Too much technology for our own good!!! I know "we must embrace technology". Ok, so where has that brought us to. Bring back the old days of carbs and cables. No need to rely on all theses computers and sensors and chips and other countries to make them. Just my 2 cents. Love the videos and look forward to them every week

Hey Doc ! When I was changing my spark plug on my street 750, I saw that there was rust on the piston head, Why is it so ? Any tech tip to get rid of rust ?

That's why I own older Harleys. That's just way too complicated for a motorcycle. Who needs all that? Getting too much like a car. Engine light, ABS light, etc. just one more thing to stress out about. Don't you get enough of that in your car?

I have a 2012 electraglide
Keeps throwing a over voltage
On acc code
Clear code turn the bike off
Then turn back on codes comes back without starting
The Harley bible says it set the code I believe it said to do that it had to be over 16v for 3 or 5 sec
But the bike was never started
I went through check the charging system
Ended up the book said replace speedo
Luckily I had a old one swap out but did no good
I finally got it figured out
Any guess what you think it was ????
Ok I will tell you
It was a aftermarket led load equalizer

I've been in the Toyota parts dept for 34 years and get the same things, customer comes in and says I have a P0140 code, What is it? sometimes I want to say I'll sell you everything related to it...and still not guarantee to fix it

Nice one Doc. There is a lot to it. and depending on the generation of system, the methods of troubleshooting can get all sorts of wild and wonderful. I just spent a ridiculous amount of time chasing down a cam sensor code on my new to me 2000 electra glide. Falsely assuming that the "professional shop" had done the job right caused me to chase all sorts of dead ends. In my frustration I had forgotten the basics: stop. assume nothing. approach it methodically. build an order of operations.

The root cause? when updating the engine to use hydraulic cam chain tensioners, the professionals had used the cam sprocket that came with the kit and installed it without ever reading the instructions in, or description of, the OEM kit; which clearly states that an original style sprocket must be used and is not included. Nor had they even stopped to wonder why the original sprocket was so radically different than the kit sprocket. That the bike ran at all in that state is a mystery I havent solved yet.

I hope they listen to you on this one, everything has changed so much over the years, look how much more wire is in a harness today an what all it goes to, Great advice Doc, HD should make a catalog of just your videos, call it Docs Common Sense ,have a good day Doc

Troubleshooting rule number 1. It's never the ECM. 🤣 maybe sometimes but if you order one and have to wait 2 weeks for it. It'll be something else.

Roger - that , Doc!

Great answer , one thing I learned on new electronics, mine was Forklifts, but same type - is 1 wire might do 2 to 3 things , atleast on the Newer Hyster forklift , one wire my do horn , and the same wire my also do 4 way flashers .
At first I was saying it was crazy , but the Voltage , and lack there of can change how a switch works , learned that in Shop class in Jr High. Using a Orthoscope seeing how Voltage works in Waves shows how it works. Confusing, but how they work .
I left forklift industry about almost 10 years ago , they seemed to be ahead of Auto industry on changing DC Voltage to AC , where a 36 volt DC battery would last 8 hour shift , changing the system to work on AC and same battery would last over 3 shifts of usage.
Wave's of power will change the World if used Properly !!!

Ha Doc what year of bike would have no electronic on it ? ( more modern bike i am asking about think buying a use one ) Thanks

Tell them they can fix it by scheduling a service appointment. My son is a Ford Tech so I get it.

You Sir, are heaven sent.

Hope I never have one as the Harley shop is far far away

When my Harley Davidson's computer throws a code I reset it to .022 !

What a bunch of bullshit , pump it two times pull the choke out kick it and go riding !

Thanks for the information Doc.

Doc your good and we all know it. Here is a question I can not find the answer to. I have what started off as a winter project. Which is know a major build. Have a 2003 soft tail heritage with a numbered paint job with only 7,000 mls. Attempting to change out the gauge and have found that the new gauges will only function on a 2004 and newer. Why is this. Dakota digital phoned me and informed me that they were out of stock and would take six month to get one made. What is the change from 2003 to 2004 and it is not the injection that should have nothing to do with the gauge. Right??

I deal with that everyday. Being a Automotive Technician. They go to a part store & get the codes read. Bring a part. I say. Do you want me to install your part, or fix your problem
