Dashboard failure when reading 93lc86, modification chevy Sonic / Aveo 2013

**PowerCheck** · 9th July, 2019, 05:20 PM

Hello everyone, I have a problem with a chevrolet sonic / aveo 2013 dashboard. I read the 93lc86 memory to modify mileage, and when reading with the upa programmer, I read all of FF FF. I put the memory back in the dashboard and it does not show me mileage and turn on two lights that did not light before. I wanted to know if you can give me a help to return the dashboard correctly, and I learned that the mileage is modified in the BCM. I await an answer, and I apologize for the translation of the google translator.

you read and did not program ?

if you did not program it , it could be bad soldier eeprom.

if i program the dump is corrupt you will have to find an equal one and copy the programming.

km sonic stored in bcm.

Mileage is stored on bcm

(Colegas, ese Chevrolet sonic lleva el kilometraje en la bcm, no en el tablero.)

Hello, you can try this file, I do not know if it's compatible

**jomberykaso** · 13th July, 2019, 05:19 AM

First you need to put the same Vin Number from BCM or Chasis of car in this file.

Good Luck!

Thank you very much Jombery for the contribution. Do not disassemble the BCM memory. The functions of the dashboard do not work well yet, so far with all the files q probe of the contributions do not manage to operate 100% the dashboard. Your last contribution of 16 bits improved by 80%, your contributions and experience are appreciated
