Toyota Hi Lux Mileage Correction

[Smurf786]

Hi Guys,

What's the best tool to use for mileage correction on 2014 Toyota Hilux?

Also is it a cluster out job?

Thanks

Any eeprom programmer, read eeprom 93A66 in 16 bits, then search for a pencil and paper and write your desired mileage, divide it by 17 and the result you must convert it to hexadecimal, then repeat code in 17 instances from adress 0000 to 0021.

From 0022 to 0043 put FF's

Good Luck!

I want to buy from a UK seller as I am from UK and want fast delivery. I seen this item http://www.ebay.co.uk/itm/112098827849

I contacted the seller and he said it won't read 93A66?

Is this correct? I want to buy full kit for future projects aswell...

[jomberykaso]

93A66 must be read like 93C66

I should have the upa usb tomorrow just been looking into it and was wondering do I need to add power on it or will it power by usb? Do I need to change any jumpers on it? Which way round does clip go on and which way does it plug in on the programmer?


Many Thanks

You must desolder eeprom from cluster and solder it in eeprom adapter of UPA, see image:

* Then plug in the eeprom adapter to Upa Usb.

* Open Upa software and select the correct eeprom, see image:

* Then you must select eeprom 93c66 x 16, see image:

* After that, connect your Upa to the computer using usb cable,( does not need 12 volts) see image:

* Once you have done all here described, select READ in Upa software, then select VERIFY, see image:

that is procedure to read any eeprom mate.

To program new mileage do it the following:

You can use windows calculator or pen and paper.

* Write your desired mileage, divide it by 17 and the result you must convert it to hexadecimal, then repeat code in 17 instances from adress 0000 to 0021. See image:

From 0022 to 0043 put FF's, see image:

6.JPG

* From adress 01DE to 01FF put all with FF's, see image:

7.JPG

After that, select PROGRAM in Upa software to write new information, then select VERIFY.

* Desolder 93c66 from eeprom adapter and solder it back to cluster (remember Pin 1)

Job is done...Good Luck!

Thanks those instructions are very good and ive got my programmer but I'm getting vdd/vcc out error when reading? I have continuity on n15 fuse also.

[Smurf786]

I had to add power and managed to read eeprom. The current mileage is 54449 miles want to change to around 31200. I'm trying to calculate hex to dec on the original file it is 83 0C and windows calculator calculates at 33548 which is wrong? Where am i going wrong? Please correct mileage on eeprom

Change all the 83 0c to 2b 07,and the two instances of 82 0c to 2a 07....All on the top lines
