Hi - I would like to know if it is possible to change the odometer reading on the electronic dash display on the (8th Generation) Mitsubishi Legnum (Estate) or Galant VR4 (Chasis codes EC5W or EC5A) 1996-2002/3.
I have disassembled the dash and just beside a very large chip which is connected to the LCD display there is what looks to be a 8 pin EEPROM chip with the following markings:
93C46CB3
93A631
MAL
ST (logo)
As far as I can figure out from Google this is a Microwire compatible serial access eeprom. Unfortunately the cheap Ģ9 eeprom programmer I got off ebay seems to throw up odd results whenever I try to read it (using PonyProg) so I assume it is protected? Would one of the Diga-Consult models work with this?
Thanks |

| Remove the 93c46 from the board read it and post the dump complete with the current mileage/kms. and someone will correct it for you. Arthur. |

Thanks for the info guys. I had assumed one of the many Mileage correction gadgets would work - but getting someone else to do it avoids the fun factor and sense of achievement of doing yourself.
But - I was hoping to avoid desoldering the chip if I could.
I have read around a bit and it seems in-circuit programming of these eeproms should be possible by either using a lower voltage than standard as this adaptor suggests to avoid interference from the MCU or other parts:
http://www.arlabs.com/adapters.htm#IN-CRCUIT%20SERIAL%20EEPROM%20ADAPTER
or by connecting an MCU Reset Line (RST) (presuambly to the microcontroller chip not the eeprom??) somehow:
www.kanda.com/datasheet/serialwb.pdf
Though I don't think that should be necessary since the likes of dashfixer and diga-consult just connect to the eeprom don't they?
I'll try reading with a resistor inline with Vcc to see if that works. If not I'll attempt desoldering.
Cheers, Phil. |

Its depend on your programmer that have using,
if you are using a programmer that has an ability to read/write it in-circuit
you don't have to remove the chip
this chip is easy to remove, and as you said at your previous post you try to
read it in Pony programmer, this chip can read by Ponyprog if you remove it
use menu microwire 16 bit --> 9346
for your Pony interface setup, uncheck all box Polarity control lines
If you want an easy job that no need to remove eeprom,
you can buy an odometer profesional tool, most of odometer tools
have ability to read eeprom via in-circuit
But dont waste your money for clone tools if you are a beginner
You cannot learn on clone tools because it has no aftersales support
Clone tools are only for user who can handle it and not wanting a support from the seller
