A greeting to all,
It would seem that the ecu has been tampered with, because the silicone closure is white and not grey, but, except this detail, I doubt that the cause can be due to some external problem and not the ecu itself.
In other words, I would not scodificarne a new deal burned as soon as mounted, for this reason I ask if it has already happened to someone be only the ecu was burnt without problems to the electrical system.
Thanks
Usually the units you autoproteggono against short circuits.
What makes you jump, in addition to causes cases, they are usually the overvoltaggi, the reversals of polarity and infiltration of water.
hi happened to me and something similar, of course, and good to give a controlled plant eletrrico I have not found anything abnormal in the system, I put an ecu and already a year and all goes well
it may happen that you ruin the file inside the ecu, in other words, I have a great point with the symptoms of the ecu route, I made a bck and copied to a another ecu from the breaker ...same symptoms can happen, or are on the wrong path?
obviously you're on the wrong track.
check ground to engine and try to replace the fuse box in the engine compartment.
thanks for the advice ... I realized that by disconnecting the injectors, or the phase sensor, the ecu doesn't register any dtc how to explain this?
check the system charge, and any wiring shelled......
not ruled out a failure of some final and driver and then a defect in a stand-alone ecu.
The wiring is intact. .. I found a ecu that instead of being a 6f3 p7 hw04p is a 6f3 p1 hw04p copied in the well can go?
yes, in the past I have already made a clone. I have written the entire backup in BDM, and it worked.Quote:
