odometer correction little problem

[mvtamele]

hi people i got a toyota raum to correct mileage and i went to Toyota Raum speedometer repair pictures toyota odometer pics (http://tachosoft.com/pics/toyotaraum.htm) to see the eeprom location and i saw that i must connect 12volts + and -
my question is i must use the car batteries or can i use power supplier regulated to 12volts?

sorry for my english

Every car I have ever done, i've never connected power while programming. I think the power diagram is for you to test the cluster before/after programming, not during. I use a regulated 12V power supply on my bench to test odometers.

Hope this helps.

did you do in circuit system programming in these cars?

In circuit? I usually pull the 93Cxx chip off the board, but a bunch of times for most Toyotas I use a clip, and make sure jump any crystal on the board.

I use an old car battery which seems to work fine.

What is the best website or software to view pin out diagrams for clusters?
