Help with EEPROM 93C56SI in Toyota Hilux


Hi,

Trying to learn about the content in the eeprom that stores the mileage now I have damaged it and I do not have a correct copy of the original content to restore it.

The odometer shows the mileage but flashing/blinking and I think it will not work when connected to the vehicle.

The car is Toyota Hilux 2007 Kun25 Dashboard 7G9H31089A6 processor T5AX6F-5CR7, actual mileage 179129Km


BR,

Rolando
