Finally, had the RS232 to RS485 converter cable wiring diagram so I managed to resolder the wire contacts that connect to the Mb Star C3 multiplexer side.

The cable I bought from ebay had crappy solder points that only worked for a few times before breaking off, and disconnected from the connector/plug.

I can line up the wires with connector and reference it with the ABCDEFGHI..etc on the multiplexer if I knew which color connect to which pin on the cable connector. Unfortunately there are too many wires loose in there for me use trail and error.

Reference: RS232 to RS485 cable pinout

RS232 cable pinout:

if i good see,this 232 box emty
check com to 485
1-
2-N M
3-N
4-H
5-LPST
6-K
7-F
8-G
9-J

RS485 cable pinout:

electrically isolated RS485 communication interface to the PC serial port

EIA-485 cable usually made with twisted pair (like EIA-422) and may span up to 1200 metres. The recommended arrangement of the wires is as a connected series of point-to-point nodes, a line or bus. Ideally, the two ends of the cable will have a termination resistor connected across the two wires and two powered resistors to bias the lines apart when the lines are not being driven. The value of each termination resistor should be equal to the cable impedance (typically, 120 ohms for twisted pairs).

The pinout, simply put, is that colors connect to the following pins:
Purple – Pin 8
Yellow – Pin 5
Orange – Pin 9 (or Pin 4), on one schematic I looked at they are bridged.

Looking at that schematic (I’ll link to it below), purple connects to "G” (which is not the G on the cable because the letters are flipped in the key on the schematic!). It looks like Yellow connects to "R”.

With the help online, I’ve fix the cable.
I’ve tested my cable and it works now. Great!

wiring instruction here…definitely easier to understand…good for those not very well versed in reading schematics above… Wish it helps

If the cable is unluckily broken to death, recommend you all to use the one with golden box from mbstartool. It’s said that that’s the best quality RS232-RS485 cable.

2.The airbag lights on all the time.

3.Access professional decoder detection and clear the DTC.

4.Disassemble the car, find the airbag computer board, confirm the chip.

5.Open the software, enter the corresponding operation interface, find the physical wiring diagram.

6.Perform physical wiring in a no-current environment and confirm that it is correct before

powering on. After reading the data, please save the original data! If the software supports

automatic repair, please repair it at the prompt of the software; if the software does not support

repair temporarily, please select the custom operation the first time consult the manufacturer’s

Toyota Prius 2005 KM reading & writing Digiprog 3 has problem,orange 5,Carprog,Digimaster 3 are all ok, go on reading for instruction.

Car model and year: Toyota prius 2005y dash

Purpose: Read and write KM

Tool to test:

1. digiprog 3: Failed

Using soldering points as it is showing in manual. After reading I got wrong mileage 1114095km…original mileage is 275 000km. but after writing that km which you need, dash shows everything ok in car.

2.orange 5 programmer + nyo : success

I read it with orange 5 programmer without any problems. Calculated with nyo, as landruiser 93c66. Attached 100% working pinout reading in circuit, maybe someone would be useful this post in the future

3.Carprog full firmware V8.21 : success
Carprog is ok for tis dash–prius 93c66
Change KM Toyota Prius 2006 93C66 for example:
Remove unit from car. Open it and find internal 93C66 EEPROM memory inside.
Use the Carprog A4, A5 or A6(due to situation) EEPROM adapter and change mileage.
In most cases need to remove EEPROM from the board.
Open carprog full software
Select Dashboard->Toyota->Prius->Prius Yazakj 93C66 v0.4

Manually enter mileage you desired

Press Write KM

Write KM success.

4.Yanhua digimaster 3 : success

I recommend Yanhua digimaster 3, it works for Prius 93c66.

Method: it needs to dismantle the dashboard and read the data.
