2000 Accent ECU fuse

My daughter's car keeps blowing the EUC fuse. I took it to the dealer and they were unable to help me solve my problem. I can't trust the car enough for her to take it back to school with her. On a couple of occassions the check engine light has come on and it looses power on the highway. Any help would be appreciated.

Try by unplugin the oxigen sensors, specially if this car has been in an mufler shop for catalitics or mufler repairs, sometimes they are not to carrefull and might damage an oxigen sensor, this sensor are located on the mufler pipe, and they look similr to an spark plug.

99 vw jettal 2.0 gas fuse 29 15amp fuse keeps blowing-no spark unpluged coil and fuse keeps blowing. help please


Thats the fuse for the ECU, engine control module, and is a 15amp for gas 2.0. i would locate the ECU which is under the center of the plenum in the engine compartment and disconnect the long plug. Check for green discoloration on the multipin connector. Sometimes moisture will get in there and short some of the pins together. Leave ECU unplugged and replace the fuse. If it still blows cause is between the fuse and the ECU.

My 318 speedometer quit working replaced 2 speed sensors work for some minutes stop the car then quit how can i fix that


bad sensors are less common than a faulty ECU.
the OBDII readers they use to trace problems in the car are read through the ecu, not testing the sensor itself, but the reading of it from the euc.

my bmw experiences leads me to the wet eci box.

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
compartment.

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
sensors....

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

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.

I have a 2000 Hyundai Accent that keeps blowing the ECU 1 Fuse. I can change it one time and it will last for three weeks then before you know it I can change it 5 times in one day. What does the ECU 1...


The ECM1 fuse blowing usually indicates that the fuel pump wires shorted inside the tank. If you drop the tank and remove the module, you will probably find the insulation burned off the gray pump wire.

Body ECU


The problem is not 100% solved. I have figured out that the problem is in the ground circut for the "Body ECU" system. The only circut effectfed is the door, ignition switch ilumination. If a ground is forced to the circut it works oK.
What I need is a diagram of the internal workings of the "body ECU". I have not yet removed it but it can be much more than a bunch of relays. By the way tell the guy with SD22 Nissan to search SD22. The sole distributor for that product is located in SanFran.
