Title: brick ecu me 7.5 Post by: jjuuaannk on May 09, 2018, 01:58:24 PM Hi, I have a problem with an ecu brick,
I was flashing normally and it took longer than it should, let it finish and the car did not start anymore, boot mode and I could do it load the previous map and surprise as it does not start no light light checkengine no light epc Anyone else have happened? the intendant 3 or 4 different maps that previously worked without working equally Thank you Title: Re: brick ecu me 7.5 Post by: eliotroyano on May 09, 2018, 05:19:52 PM Hi, I have a problem with an ecu brick, I was flashing normally and it took longer than it should, let it finish and the car did not start anymore, boot mode and I could do it load the previous map and surprise as it does not start no light light checkengine no light epc Anyone else have happened? the intendant 3 or 4 different maps that previously worked without working equally Thank you Hi JJ did you test ECU on bench? do you got a diagnostic session on bench after reflash?

Title: Re: brick ecu me 7.5 Post by: eliotroyano on May 16, 2018, 05:37:33 AM Hi friends I have been helping jjuuaannk with his problem. ECU was bricked during a reflash of a Launch Control version of the tuned software his was using in the ECU.
The following attemps via boot mode was done in chronological order without sucess. 1- checksumm checked flash + serial eeprom dumps. Also death code was not present. 2- previous working tune 3- oem software into 29F800 flash eprom 4- other oem flash + serial eeprom from another working ECU. 5- last test was done in another ECU using checksumm checked dumps working nicely on bench. Bricked ECU responds in boot mode but does not work at all for diagnostics on bench, neither in car. I can post dumps in a while because we out of Office. But do you think about this problem and tests? Title: Re: brick ecu me 7.5 Post by: _nameless on May 16, 2018, 05:48:31 AM Flash is Eprom not Eeprom. You still have not flashed the Eeprom like said earlier in this thread ^^ should be a st 95040
Title: Re: brick ecu me 7.5 Post by: eliotroyano on May 16, 2018, 12:05:10 PM Flash is Eprom not Eeprom. You still have not flashed the Eeprom like said earlier in this thread ^^ should be a st 95040 Thanks for your reply Marty. Both 29F800 and 95040 was reflashed with dumps from a working ECU (same HW & SW versions) without sucess.

This is very extrange thanks
Title: Re: brick ecu me 7.5 Post by: _nameless on May 17, 2018, 07:10:37 AM Possible hardware damage? Was the pcb shorted by mistake when put into bootmode?
Title: Re: brick ecu me 7.5 Post by: eliotroyano on May 17, 2018, 02:34:55 PM Possible hardware damage? Was the pcb shorted by mistake when put into bootmode? Maybe possible but boot mode was done carefully to avoid any problem with PCB.

Title: Re: brick ecu me 7.5 Post by: eliotroyano on May 18, 2018, 05:03:35 AM During my research I found similar problems with the same ECU. My question after all my tests is: is really a software problem or is more hardware related? I ask because I have tested whole software in other ECU (different number) and works nicely on bench. Also diagnostic interface test indicates that K-lines are "OK" but CAN not like in the test ECU.

I made the right food and everything worked! |
