These will also work on the 07 & 08 bikes. There are additional codes for the 08 bikes not listed here but are listed in this same section in another post.

These apply to 04 and later bikes with the serial bus.

The IM (instrument module) is capable of displaying DTC's (diagnostic trouble codes).
Speedometer Self Diagnostics: The speedometer is capable of displaying and clearing speedometer, tachometer, TSM/TSSM and ICM/ECM Diagnostic Trouble Codes (DTC).

1- Turn Ignition switch to OFF & Run/Stop switch is to Run.

2- Push odometer reset button in & hold.

3- Turn ignition switch to Ignition and release odometer reset button. Background lighting should illuminate, speedometer needle should sweep its full range and indicator lamps (battery, security, low fuel, check engine and cruise) should illuminate. The word “diag” should then appear.

4 - Push the odometer reset button once and you will see the selection menu "PSSPt" with the first P flashing.

5 - Each letter represents an area of the diagnostics module. The module that is flashing is the one you are going to check. To move from one letter (module) to the next, you push the odometer reset button one time. (from P to S to SP to t and back to P, etc.)
P = ECM/ICM (Electronic Control Module [EFI] / Ignition Control Module [Carbureted)
S = TSM/TSSM (Turn Signal/ Turn Signal Security Module)
SP = speedometer
T = tachometer

6 - To get the DTC within an area of diagnostics, push and hold the odometer reset button in for 5 seconds and release. If there are any DTC’s the code will be displayed or the word “none” will appear if there are no DTC’s. Push the odometer reset button again to view additional codes if they exist.

7 - Record the codes.

8 - If DTC’s are not to be cleared, Press and release the odometer reset button. Part number of module will be displayed.
NOTE: To determine if a code is current or historic, clear the displayed code by pushing in and holding the odometer reset button ( longer than 5 seconds) until 'clear' comes up. Release the odometer reset button. Turn OFF the ignition switch. Run your bike and shut it down then recheck the DTC’s again by repeating steps 1 to 9. If the code is current it will reappear.

9 – Press and release the odometer reset button to continue to the next module.

10 – Turn Ignition switch to OFF.

On models not equipped with a tachometer "No Rsp" will appear when the tachometer identifier is selected.

"No Rsp" will also appear if the run/off switch is in the off position when doing this procedure.

Also if the code set is a historic code (not a constant light) after 50 start and run cycles of at least 30 seconds each in duration, the light will extinguish itself as long as the error hasn't occurred again.
If it were a current code, the light would remain lit while running.

-----------------------

AFR – Air Fuel Ratio

ATS – Air Temperature Sensor

BAS – Bank Angle Sensor

CCM – Cruise Control Module

CKP – Crank Position Sensor. The CKP generates an “AC signal” which is sent to the ECM where it is used to reference engine position (TDC) and speed. Home position established by taking readings off the 22 teeth on the alternator rotor.

DTC – Diagnostic Trouble Codes

ECM – Electronic Control Module. (The Computer) Computes the spark advance for proper ignition timing and fuel control based on sensor inputs (from CKP, MAP & TP sensors) and controls the low-voltage circuits for the ignition coils and injectors. The dwell time for the ignition coil is also calculated in the microprocessor and is dependent upon battery voltage. The programmed dwell feature gives adequate spark at all speeds.

ECT – Engine Coolant Temperature. Sensor also controls the cooling fan relay that provides 12 Vdc to the fans.

EFI – Electronic Fuel Injection

EFP – Electronic Fuel Pump

ET – Engine Temperature sensor

FI – Fuel Injectors

FPR – Fuel Pressure regulator

IAC – Idle Air Control actuator

IAT – Intake Air Temperature sensor

ISS – Ion Sensing System…detonation detection

MAP – manifold Absolute Pressure sensor. The MAP sensor monitors the intake manifold pressure (vacuum) and sends the information to the ECM. The EMC then adjusts the spark and fuel-timing advance curves for optimum performance.

TP – Throttle Position Sensor

TSM/TSSM (Turn Signal/ Turn Signal Security Module)

VE – Volume Efficiency

VSS – Vehicle Speed Sensor. Used as an input for idle speed control

Updated 1/1/08

The code i found is P1358 Intermittent Secondary Rear EFI can i get any assitanct with this.

Sure can.

That code is a bit misleading. It pertains to the secondary ignition meaning the plug or plug wire. Quite often the plug wire is not seated fully on to the plug or the tip of the plug needs to be screwed on tight as it is loose and the ION sensing will detect abnormal resistance to fire the plug and set that code.

This will explain ION sensing a bit more.

http://www.hdtalking.com/diagnostics_alarms_security_and_fuel_injection_rel ated/762-tc_ion_sensing_detection_explained.html

Check the connector that is a few inches up the wire from the sensor itself. Open it up and see if it is clean and connected well.

Great tips there Glider ! you are the man :D this will be a big help down the road for me. Thanks bro

Glad to be of help. The procedure has to be followed closely to work right.

Glider you seem to be a lifesaver here =)

What is the "P0501 VSS Low EFI" code?

P0501 VSS Low EFI" code

(VSS) Vehicle speed sensor on the transmission. Usually they are covered with fuzz (gear material) and when this happens they can no longer read the fourth gear teeth on the gear so you get the code. Cleaning will restore it's signal but replacing is usually the way to go.

If you are using syn 3 or a 20/50 engine oil in your trans, I would suggest using a gear lube instead and this problem will be greatly reduced if not eliminated. The fuzz is gear material (wear) usually from the wrong lube in the trans.

They have to work unless you are doing it wrong.

Meanwhile, this is probably the problem for the speedo/tach and security light lite and blinkers.All related. Make sure you run/off switch is ON.

Speed Sensor Pickup Problem Symptoms - Harley Davidson Community (http://www.hdtalking.com/electrical_and_lighting_systems/763-speed_sensor_pickup_problem_symptoms.html)

The brake light may be another issue.

It seem this is where I want to be regarding the DTC's. I have a P1001 System Relay Coil Open/Low EFI. The events leading to this were as follows, warranty replacement of front and rear pully, some issue about sprocket overly torqued onto shaft and misaligned at factory. Was fixed, rode bike home, and it worked fine. Next morning would not start, start switch did not even engage starter, just a click in the starter relay, with fully bright headlights, etc so it was not the battery. Called dealership to pick up bike. Next day pulled bike onto driveway for pickup; just for the sake of trying, tried to start bike and it started. But engine light came on went off then came back on for a few seconds and it then stayed off until next start-up. Found this site, found the error, but what does it mean??? Bad relay, something else?

That could come back as a few things but probably the starter relay itself or the connections to it.

Glider,
P0373 CKP Sensor Intermittent EFI? What does it mean. This was the code I got after my pressure washing incident... I just cleared it, I was wondering why I got it? bike is an 07 nightster stage 1 with a fuelpak. Thanks

THE

That's the crank position sensor, it could be a bad connection or water from the washing causing it. That sensor gives the feed back to the ECM which in turn sends out the proper signals to run the engine properly.

Should never use a pressure washer on these bikes, there are a lot of places where it is not water proof and the pressure from a pressure washer will infiltrate many places where you don't want water and cause problems and codes.

I had the same p1358 code and I was able to clear it. Thanks for the great info.

Did you find what was causing it?

Glider..been riding in the rain most of the day...very hard rain...system set a code and bike started cutting out. Did this for a few minutes. When I got home I ran the diagnostic code steps...I have a 2004 Road King...the code I got was P1352...P1353...And P1356....Front ignition coil High/Shorted....also front cylinder no combustion (makes sense) and Rear cylinder no combustion...then it showed the mod P-number...my question is it started running ok after a few minutes...the check engine light never came back on suggesting a code was historic..and going through the procedure it tells me its a historic code as it cleared....so did riding in the rain cause this to happen...everything seems to be ok now..Help!....:21:

More than likely with those codes all set at the same time, I would say it was the rain that caused it to set the codes. It doesn't take much to change the resistance in the plug wires to give you the no combustion codes when they get a bath. It's called ION sensing on these bikes.

Whoa! You are the man..thank you so much. We were doing a" Hawgs for dogs" poker run, and it was over and on our way home...My wife ask when it cut out a few times " what the heck am I doing is raining quit playing"..I just said ok we were kinda far from home so did not want to scare her...lol..I was scared enough for the both of us...lol Again and as usual thanks so much for the fast response... :D

Glider, you seem to really know your stuff. I just got my first bike last weekend. On the ride home the throttle was cutting in and out, seemed like a fuel issue. Anyway, had to tow it home (last 10 minutes), started it up last night and it runs but the engine light comes on and it idles sporadically. Ran the diagnostics and got 3 codes, B1004, B1005 and U1300. Any thoughts on what this might be?

A little background, the bike is a 2006 Street Bob with just 1800 miles on it. Previous owner barely rode it over the last year. I'm guessing there may be something wrong with the fuel mixture (I put premium in it half way on the ride home) not sure if I kicked up some sediment then or something. I welcome your thoughts, cause I want to get this baby back on the road.

The 1004 & 1005 are contradicting codes, more than likely a connedtion loose or something along those lines. Check the battery connections and if necessary remove/clean and reinstall them. Check the voltage at the battery both off and running at around 2K rpm/s.
The U1300 is the feed that goes to the instruments and may be the cause of the whole problem in itself. Possibilities would be corroded of bad connections at the key switch or back of the speedo.

Hard to tell exactly from here.

Quick updated. Battery was good, got her started, reset the codes to see if it would kick back the same ones. When I rode it it ran rough, eventually broke down again and spit out different codes (ignition coil related), so I had Harley come pick her up. After a few hours of diagnostic tests, turned out the ECM was bad. Have to replace it, now sitting around waiting on the part to get here, this week sometime (of course it is when teh weather is looking its best).

what's the cost of an ecm.....maybe look into buying an aftermarket one if the cost is close to the same. I'm really liking my thundermax autotuner. I think their running close to $900 right now though.

Another update. ECM was about $400, but covered under warranty by Harley. Originally the dealership did not think it would fit under warranty, but the ECM is covered for 5 years. Lucky for me cause the ECM was pricey, plus it required a new race tuner, so in total I was looking at close to a $1000 for everything, but turned out to be nothing. Overall, I am satisfied, but still waiting on my bike to get back to me. Now the dealer is replacing the front rim (I believe they bent it when they picked it up), works for me though putting one of the black typhoons on, just have to wait for it to get in.

Good afternoon - My Dyna lost all spark last night. After running the codes, It came up P0261, P0263, U1301, P1002 and P1003.
I have carefully inspected the wireing and connections. Cleaned all connections. Any more words of advice until my Service Manual arrives?
It will cough now and then, but not run.

With those codes it sounds like a bad connection possibly at one of the plugs in the harness. Have to go through them , open the plugs and check them for corrosion or loose fit.

My Dyna turned out to have a bad ECM also. Is this a common problem? It ain't a cheap repair.

It's hasn't been a problem in the past but recently it seems to be getting worse.

can't believe how much info i can gather from here...anyways here's my dilema. right before i put on my mods i turned in my bike for it's 1K service and told the service guy that the bike is choking/coughing on 4th/5th in mid,high throttle. after the service he told me that it's NORMAL for 08 XL1200 and i NEEDED a bigger/better AC for more air intake...so i bought a SE stage 1, and for some reason i went all out (V&H short shots, PC III) test drove it and had the same choking problem...ran diagnostics and heres the codes P0107 Map Sensor Open/Low EFI...lil help pls...service manual is on order but can't stand watching my bike sittin here

I keep constantly getting these 2 error messages on my 2004 Night Train:
P1357 Intermittent Secondary Front EFI
P1358 Intermittent Secondary Rear EFI

could this be a bad coil or wires pls help

Could be either but I would put my bet on the wires or even possibly the plugs, like the top of the plug where the wire snaps on to, is it loose? How old are the plugs?

This seemed to start happening about 3 weeks after I had my bike in for it's
5k service. The boots don't seem loose putting them on and taking the off. The plugs are still original from 04 as far as I know. The code seseems to trip around 4000 rpm under hard accelertion(such as getting on the highway). The weid thing is when the code is tripped (the check engine light coming on) at 4000 rpm the tach bounces back and forth between 3800 rpm and 4200 rpm. Thats why I was thinking it could possibly be a bad coil. Or possibly a bad ground. I dunno I am puzzeled as to what it could be.

If you think your plugs are 4 years old replace them right now! It's a good place to start anyway. some people replace there plugs every oil change. I replace them every year and check them every oil change

How about how this works for a 2001 Softail Deuce? Thanks
