Fixing a CBR 929 ECU
zhlédnutí 27KPřed 5 lety
This is a repair for a CBR 929 ECU that triggers the injectors but not the coils. If you have a bike that is spraying fuel (look down the throttle bodies while cranking to check) but isn't making any spark, chances are this is what is wrong with it. I had two that died in the exact same fashion, and there is a few more accounts of this happening on various forums. If you don't feel like listeni...

Excuse me a question.... But the resistori are 47 or 0.47 Ohm? 😳!
0.47 ohm. They are very small.
Very informative, thank you.
Wow! Sam thank you so much for sharing your knowledge in this great video! With your help I have just repaired my 2001 CBR600F4i which had lost spark. As an auto repair tech I am very familiar with electrical diagnosis & repair. I found I was able to create & clear DTCs for the sensors & fuel injectors, but there are no DTCs for these ignition coil drivers. After several hours of diagnosing with the service manual, wiring diagrams, and my DVOM, checking all wiring & sensors, I had concluded my ECU coil drivers were inoperative. I found and watched your video several times, then following your instructions, and with about $2 in parts I have just successfully repaired my ECU & my bike is running again like a top! Sam you are my hero!!! Thanks again for making this video!
Parts list?
Parts and full description of what I did here: www.casecoltingersoll.com/threads/646-power-steering-conversion.94718/
My ecu was broken wasn't fireing up the gas pump but after your explanation I just decided to buy a new one 😅
I'm glad to see everything fits under the dash amd you didn't hack the dash up. I have a power steering assembly off of a deutz that I am going to try and fit on my 646. I need to disassemble the tractor to rebuild the loader valve. While it's disassembled I'm going to look into my options for power steering.
It’s definitely worth the time to add, it’s made the tractor so much better to use (but we do use it a lot for carrying heavy stuff) Post it up if you get it done, be cool to see another one!
Hi Sam, This is an invaluable video so firstly thanks for the details. I bought a 2002 CBR 600 F4i, it was a non running project bike and I got it sorted and all was good…until randomly one day the FI light started flashing, code 33 which is ECU. The bike still starts and runs fine but this is obviously an issue. Being a UK bike with HISS I can’t just use another ECU so in a tricky spot trying to find a solution. Can I ask, what issues do these failed resistors create? Given my bike is still running fine I don’t understand why it’s showing an ECU fault and then beyond that I don’t know if it’s an issue beginning to creep in with these resistors or something else altogether. Any pointers would be much appreciated before I take the grinder to the ECU!!!!
I found that regular unleaded gasoline works really fast and doesn't ruin the board or erase chip markings..
My man everything is fine on your presentation --- only problem is i can't really hear anything with the bloody loud radio in the background?????
Hi sir I got Cbr954rr 2002 I baypass servo motor now no fuel prime no spark if I give direct power to hiss then every thing runs like crazy feul pump +fan but on its own power just fan runs non stop

Hello, I have a 1100xx with a 25 eror code. I has trying everything regarding the wires and FI is still there when I rev it more than 3000tpm. For a three days I has run it happy without FI but after 3 days FI reapear. So it must be ECU. But I think that nobody has repair this code on a ECU. Do you now why , or mabie is someonne who did this.
How do you get out the ecu out of the black box?
Can you test the CDI without stripping it down
Hey what size fuses you used ?
2 x 0.47 ohm in parallel So 0.235 ohm total

Hello Sam, I have CBR 600 RR 05/06 and I don’t have sparks, I have checked everything and I think the problem is in ECU/CDI. I want to change resistors like you, but I don’t know the position of them. Do you maybe know is it the same position as on your ECU? (Because I want to cut the plastic) Thank you in advance!!
I'm sure this is too old to ask but I am working at doing this on 4 of my ecu's that bike is killing. I personally cut the top ledge with a dremel and using wires to solder to board so I have a lil more room to stuff new resistors in and seal back up with permatex. But my question, is it the 2 resistors that have " NPR1 0.1 OHM F" stamped on top? Looks like same location as urs but hard to tell where they are already removed off unhoused circuit board an hard to see in one tht is just cut open.
Both the ecu’s I took apart the lettering came off the top of the resistors so I don’t know what they said. If you can clean the board off they are numbered R743 and R744 on the connector side of the board. You can see 743 in this picture, 744 is to the right it’s a little harder to make out www.dropbox.com/s/h124p1odmfu8p3e/20200423_183057.jpg?dl=0
I’d like to ask what purpose do the transistors in the down right corner serve
Sam can u help.
Where on the board would be damaged if the fuel pump was not priming?
How can I test my ecu, I have a 01cbr 929 I just got and it was workint completely fine before I swapped the frame
Hi Sam I was wondering if that would cause crank pos sensor and cam pos sensor to loose 5V signal ? thanks for the information on the resisters.
The cam/crank sensors aren't supplied voltage, they create voltage. One wire should be grounded, the other wire goes to the ECU. With the motor stationary there should be 0v, and the voltage will spike every time a tooth passes the sensor when the motor is rotating. To test them you unplug and probe the two wires going into the sensor, you need a peak voltage adapter to make sure they are in the correct range but if you have an analog meter you can at least check if they are completely dead. If they are working you'll see the needle move but the actual reading is meaningless so it doesn't necessarily mean it is working correctly
My cbr keeps blowing fuses on the white fuse holder mounted to the side of the big fuse holder. It's a common wire that goes to the Injectors, ecu, ignition side. A forum dude said that a replacement ecu fixed the issue. I have my ecu stripped and ima trave the pin and replace components until it works.
What a pain in th3 ass. My next bike will DEFINITELY be carburated 🤦♂️ my cbr f4i will be for sale shortly.
buongiorno, devo chiederti una info, riguardo la mia cbr 929 anno 2000, praticamente il motore non risponde in modo regolare, manca di potenza, tutto fatto il controllo, mi rimane solo la centrale da provare, molto probabile risiede li il guasto. in ogni modo la centrale me la potete riparare voi ?
hey Sam, Scott here. So I'm getting no spark and no prime. I've removed all the potting from my ecu and I'm a little lost... k on the middle grounding rod where you have the 5 resisters that have screws in them ..are all of those supposed to read the same when testing the outer 2sides of each fork in the middle?
Hi Scott. The problem outlined in this video doesn’t cause no prime, only no spark. No prime is usually the ‘pink wire’ (from the ignition switch to ecu, should have around 9 volts when key is on), or HISS if equipped, or the safety circuit (side stand, clutch switch, etc)
Regarding the 5 parts, the ones screwed into the large aluminum heat sink are IGBT’s not resistors. I don’t know if they can be read correctly without removing them from the board, depends a bit on circuits they are attached to I think.
@@vpsryder hey Sam thanks for getting back to me well I'm just trying to figure out when I bought this bike it wasn't running and I got it running after about a week because I found out about the pink wire now I have replaced my regulator rectifier stator and cam pulls generator. now as I stated I bought the bike running so I've been using a 9 volt battery to use to drop the voltage instead of a zener diode but now that I've replaced all these parts I'm not getting spark and I've tested out the resistors that you have been talking about in your video and they test fine I guess they're within spec from what you have explained so I don't know why I'm not getting any spark now when I use the 9 volt it only triggers the safe mode if I have my paper clip shorting out the plug and that works only if I apply the 9 volt but now when I apply the 9 volt the fuel pump won't come on and the fuel pump is good because if I jump for it it works I just can't figure out why it's not accepting this 9 volt drop anymore any thoughts cuz I've been working on this for forever in a day months almost a year ....
Hi Sam, is there a way i can test if its those 2 baddies before i open the ECU? I am getting power on the ignition coil plugs, fuel pump prines, it cranks but won't start.
I know this is old. But I have a 2001 929rr. And I'm getting a no start. No crank fault. I get a solid red FI light on the dash. The neutral light does not come on. Is this a faulty ECU? I can't for the life of me figure this thing out.
I went to put the arrow on my motorcycle CB 919 HONDA HORNET I pierced the module with a screw, is it fixable

Sorry about the stupid question, I watched the video and got my answer thanks alot great video
Where is the chip located that keeps the tune at plz help
Please stop slamming the ecu off the table :)
I have fried my GSXr600 2006 ecu, it says CHeC on the dash screen.
Will you fix mine and how much please?

Hi Sam, I have a 2004 CBR and the F1 fuse keeps blowing. I am thinking the ECM has an issue since I've checked everywhere else pretty much. What were the symptoms with these ECMs before you started repair? Tempted to follow you fantastic video. Thanks!
This issue wouldn't cause a fuse to blow. Really unlikely any ecu fault would cause blown fuses actually. You'll need to get a wiring diagram to confirm what fuse F powers. On mine it is for the instrument cluster, looks like on some 1000's it is the fan.
@@vpsryder Thanks Sam - you may have just saved me a small fortune. I'll have another look around. Although I have disconnected the cluster and the same issue appears. Will disconnect the fan and have another go.
I have the same issue with mine any luck ?
@Hector Vela Yes. Changed the ECU and issue solved. Could be many things though...
Thank you very
Thanks bud! You're a mad scientist! ✌🏻😎🤙🏻 I'm having a pain in the a$s time trying to diagnose a no spark issue on my CBR F4i
hi pls assist im facing the same problem.Howdid you resolve it?
@@sifisognsibandze5476 👍I did resolve it! In my case it was the ignition pulse generator. It was an extremely hard time finding the problem. What have you tried doing so far? Are you sure it is a "no spark" issue?
@@joeygunzilla6878 yes my pump primes perfectly and i verified that all my sensors work
@@sifisognsibandze5476 do you know how to read the codes? Have you tried spraying starter fluid (or a tiny bit of gas) directly in the air intake? Is your battery FULLY charged? Are you using the original key? Old or new gas? How did it stop running, While riding or just no start after sitting?
So you mounted externally from one side to the other side ? What about the 2 in the middle.. great video I’m just a little confused.. do you a post step by step .. thanks bud
REALLY interested in what you are saying, NOT the music. Clever fix - props!
What kind of cleaner did you say you was using? Had to understand.
What's up man, how do you opened a ecu?
