Is this real? My Drifter - 99 1500cc - was dead. because my ecu is dead... what can i doing my ecu problem...
when i wanna start my bike than i turn to the ignation switch and i doesn't hear fuel pump and i doesn't see no FI lights my speedometer.i have serius problem my ECU...
buy a new ECU or compatibilities a different motorcycle ECU?
help...please...
Not to be an ass, but what process did you use to determine if it was the ECU? When you flip the key on, do you have any power anywhere? How many volts do you have at the battery?
You need to do some troubleshooting to determine if it is the ECU. There are MANY more likely things that cause what you describe.
Start simple, make sure switches are in the right position and connected properly, check battery and fuses.
the battery ----ok
the junction box -- ok.--all fuses 10 A --- is it right?
all connections---ok
start switch turn on--ok
ignation switch turn on--ok
then starter motor ---works--on
but doesn't work fuel pump and other ignation systems...no FI lights...
what should i do ?
first off, have a cold beer. then check all ur ground connections an RIDE ON.
What kind of ign switch (key switch) do you have? Aftermarket switches are lots of problems. Did you check the primary fuse under the seat, at the back of the battery compartment?

my 99 1500 would not start this spring.
I put a battery tester on it, it read 13.4v so I figured I had a problem not sure what. Checked everything and couldn't find any problems, now I had no lights , dash, horn etc.
I figured I'd start with the cheapest first and since I wasn't sure how old the battery was I thought I'd get it tested
Took it to a shop , he tested it .......12.4v
I thought good but he said lets put a load on it and it went from 12.4v to about 2v in about 5 seconds....battery no good...... must be tested under load
Hope this helps
dear friends,
all test results show my ECU is death...i want to know some information and i need your helps...which are model's ECU compatibility with my 99 1500 drifter's ECU?
Did you test the tip-over switch?
Regards and such,

How about the EFI main relay?

tip-over switch? what is this?
It is under the seat in front of the battery. (the correct name is "Vehicle down" switch). It is held in place by a single Philips-head screw and a tab on the bracket locates in a hole in the frame to keep it from turning or moving. If the switch is faulty, it will prevent the bike from running. It shuts the bike off in the event of a lay-down.
The following 2 paragraphs are from the service manual:
This sensor has a weight with 2 magnets inside, and sends a signal to the ECU. But, when the motorcycle banks(40~50 degrees) or more to either side, (in fact falls down) the weight turns and shuts of the signal. The ECU senses the change, and stops the fuel pump, injectors, and ignition system.
When the motorcycle is down, the ignition switch is left ON. If the starter button is pushed, the electric starter turns but the engine doesn't start. To start the engine again, raise the motorcycle, turn the ignition switch off, and then on. When the switch is turned on, current flows through the latch-up circuit and the transistor in the circuit is turned on to unlock the latch-up circuit.
However, if the switch is faulty or comes loose on its mount, it can also go into a "vehicle down" condition and it usually won't correct until it is remounted. This bear looking into.
Hope this helps. Good luck,

we check out vehicle-down sensor...it is working correctly...by the way ECU's transistors are burned...i want to more information abouth compatibility other vulcan's ECU...
According to bike bandit.com, all the drifters use the same ECU....http://www.bikebandit.com/houseofmotorcycles/1999-kawasaki-vulcan-1500-drifter-vn1500j/o/m149609#sch77547 (http://www.bikebandit.com/houseofmotorcycles/1999-kawasaki-vulcan-1500-drifter-vn1500j/o/m149609#sch77547)
The price isn't as bad as I have seen other places. Once you get it running, you should check the charging system voltage, if it goes too high it will take out the new one, too. I'm thinking that the major difference between the ECUs is the fuel mapping. You might want to speak to a dealer you are on good terms with about this.
Here is a listing from eBay... the prices are all over the map, but generally cheap!

i wonder abouth information...
1- 1999-2000 drifters( J1-J2) ' s ECU part number :21175-1064
2- 2001-2005 drifters (R1-R5) 's ECU part number : 21175 -1064(same J models)
but J model's wiring diagrams different from R model's....R models include speed sensor...
and R models same wiring diagrams N model's..
i wanna buy ECU from ebay and i just find N models ECUs...are they compatibility R and J models?
they are different part numbers... don't know if those for Classics would work on he drifter or not.
Dear friends,
My problem is solved!!!
the vulcan 2001 classic N1 's ECU came on 2 weeks ago and it works...my motorcycle is the 1999 vn1500 drifter J1 and the diffrent ECU %100 compability of my bike......thats all...
Kinda figured that would be the case, but it's hard to tell, especially when it's someone else's bike...I've been thinking about experimenting with different ECUs just to find out....
