I've had zero responses in the general forum so thought I'd try's the story: I purchased a new ECU due to mine being kaput. The bike fires right up and runs great but... All attempts at reprogramming/mating the ECU to the rest of the bike have for lack of a better word failed. The issue? When I start the bike, the immobilizer light comes on during initial turn to on then goes out as normal. About 1 or 2 seconds later it comes back on and stays on. The bike runs great but this light is driving me nuts. When I shut it back off the immobilizer light flashes for 48 hours as normal. I've tried complete red-black-black-red key reprogramming but the dang light won't stay out when the bike is running. Any thoughts?,,,,

Location of what is referred to as an ECU in my 1998 honda accord ex v6

Hi, you cannot diasble the immobilizer by removing a chip. What you have to do is trick the ecu into believing you are using the correct key. There are bypass systems on the market for this purpose. Just make sure you get the right one for your car.

Battery cables switched

Make sure an OBD reader is used to make a connection to the car's ECU/ECM. If no connection can be made, then you can remove the ECU and test it for current and resistance. If either of those tests fail, your car needs a new computer.

I have a 87 Nissan 300 zx that every time I turn-on the key the fuse for the ecu blows. can any one help?

It could be a short in the wiring- a broken wire, or wire stripped of insulation, and touching metal somewhere. If you could look at a wiring diagram and find that circuit the fuse protects, you should be able to check the wiring without a lot of difficulty. The wire would enter the ecu on a certain pin number, and then you could check the resistance on the wire with a multimeter-with key off, and battery disconnected before unplugging the ecu. You will have to check the wiring all through the circuit, so you really do need a wiring diagram. If the wiring appears to be okay, then suspect a bad ecu. Used and reconditioned ecu's are all over e-bay. Pretty sure you could find one for your car. I just recently bought a used ecu from e-bay for my '87 Sentra, cost was $24.99, some place called auto computer wholesalers. And it works as good as a new one. Or as good as my old one, turns out that wasn't my problem, but I just kept it in the car.
Don't forget to disconnect the negative battery terminal. The ecu in those has constant power to the ecu, even with the key off. So never pull off the ecu connectors with the battery connected.
For a wiring diagram, buy a Haynes repair manual. Or register for free at, giving make, model, year, and engine size if applicable. The repair guides do have some wiring diagrams, just not complete maybe. Or if interested, you can buy a subscription for $16.99 a month (or under $30 for a full year) from It is a DIY site by Mitchell, and with a very extensive amount of help and information. I had a one month subscription there, after getting very, very depressed with my Chilton manual. Couldn't even find a credible wiring diagram for my '87 from Chilton.

My CEL is on, my code reader reads no codes, sees no live data for any sensor. the jeep seems to run okay, is ecu bad?

Sometimes the code reader will not read the Mopar/Jeep codes. This is different system, CAN system. Drive to your local AutoZone to get your codes from your ECU/ECM.

No power but plugis okay can't find schematic online

well this is under bmw but i don't know what you have for sure...

think about a wet ecu

the ecu compartment is under the windshield on the passenger side on E36

you gain acess to it under the hood....
this compartment gets wet, the ecu lays on a flat surface in that

the bottom side of the circuit board gets wet and starts corrosion.

remove the ecu, take the bottom plate off, clean the bottom of the circuit
board with alcohol and a soft tooth brush.

you should be able to see the signs of corrosion or conductive build up.

this gunk bridges solder points doing all sort s of wierd things to your
car, including false sensor readings from asc/abs controllers and other

all the way to engine failure and worst case burnt and shorted wiring

I'm on my 3rd ecu, took me and the repair boys a few years to figure this
one out.

BTW: i would get that ecu mounted above that flat surface, use some sort
of standoff to raise it so that it is not laying in the wet.

95 ford ranger does nt go into fourwheel drive. I turn the knob and no light indication its on. fuses are good. Could it be the acuator? This truck has auto hubs. it seems to me it an electical problem

Its most likely a ECU issue. I would take it to a mechanic to have it looked at, ECU may still be okay, but it should tell them the general area to look at.

No spark, '95' VW Polo

i assume you checked all your fuses. if you have no spark coming from the distributer you need to see if there is power going into it. and the ecu tests okay you might have a bad distributer.

Overheating problem, fans not running when up to temp.. Temp. sensors okay, where is ECU IG fuse located on this car.

If the fans are not running, the problem is most likely the relay. You can test relay with an ohmmeter. If fuses are ok, than the fan motor will need to be replaced.
