2014 Toyota Prius Alpha from Japan, need help with EEPROM data

**fahadv** · 16th March, 2019, 07:56 PM

Hi

I need help with my Japanese Toyota Prius Alpha (like the C and Plus), I'm using it in the UK so need it in miles, I've got the S93A66 chip off and read the data attached, as its in KM i need to save it back as Miles as a can bus rectifier has been fitted now, so it will be recording miles now not KM. Where is the KM data and how is it encoded?

It currently has 159221KM

Many thanks in advance.

Here you go, i was replacing the first three lines with data from other files and it did change the KM, although sometimes the KM would blink, and other times it would disappear altogether.

I think its in DENSO, i really want to get my head around how this data is encoded.

How do we get from say 85321KM to the actual data on the first three lines?

Can anyone shed some light?

Hey guys
A friend has just bought a Japanese ZVW30 (s93a86), 2014 5 seater Prius , was wondering if you could have his BIN file changed so it changes the console as follows:

1) to show in English and not Japanese (which line needs to be changed and why/how?)
2) KM to 74,000 - a breakdown of how to read, decode and encode would be greatly appreciated. - also is there a way to show the distance in miles?
3) is there anyway to have the car show the road speed in miles and not KMs as it need to do this for the UK roads.

I've tried lots of US and UK files but they either do not work at all (blank screen) or the KM is flashing in error. Some do work to show the screen in English so im guessing that part is possible.

Thanks in advance...

Hi mate, thats really funny, i just managed to crack my friends problem like an hour before you posted, i was well chuffed

, should have just waited

.... much appreciated though

Now im still stuck with my one (Japanese Toyota Prius Alpha) 93a66 M4 940-010 83800-47581.

I know its permanently set to KM, but is there anyway to have it do the speedo in miles, then i can just cover up the KMs on the display? that would save all the messing about with the CAN BUS.
