LOW voltage ERROR on wrx USDM
Posted: Sun Mar 15, 2009 4:08 pmhello everyone,
i have a 1997 impreza with a ej205 USDM wrx engine in it. i am trying to reflash it and i get the error...LOW VOLTAGE 11.04 volts.
now i have done some research but nothing i have gathered has solved this problem. however i am able to test and read to the ecu. i have re-installed software, and used ECU explorer to determine voltage output. voltage was lower then needed. i now have wrx alternator, and even tried reflashing with battery charger on battery. NO GO still and same error.
i do know that i need 12.61 volts to write to the ecu. however i am not sure exactly what line that goes to the ECU that needs that actually 12.61. i know that my car is Reflash-able because the last business that i brought the car to reflashed some codes out of the ecu. I.E. 03 wrx's come with fuel pressure in fuel tank which my car does not have. i do not have a cell this way. i cannot get into contact with that person who flashed the car because he no longer works there and the business wants $$$ to diagnose the problem, even though the are the ones who wired the car.
any information would help. thanks.
