2024 Geely Coolray Pinout to Xhorse Multi Prog

It’s a 2024 Geely Coolray, and I need to correct the mileage.

The panel looks like this:

First, remove the instrument panel. To do this, pull the visor up with one sharp movement, unscrew the 12 screws, and then remove the panel. The rear panel cover is secured with clips and 4 screws.

EEPROM chip which contains the mileage.

We read the m24c08 microcircuit using any convenient programmer, but it’s necessary to desolder it; you can make a mess with a clothespin.

Let’s remove the dash panel, lower the fuse box, and unscrew the four BCM mounting bolts. It’s on the left pillar at the top of the front; it contains a bunch of components. Removing it is very inconvenient. Next, we need to find something to read it with. There’s no EEPROM there; all the information is stored in the processor. The Xhorse Multi Prog programmer helped us with this. The connection is easy, but you’ll need to be handy with a soldering iron.

We read it, sent it to the same programmer, uploaded it back to the BCM, and then re-entered it into the instrument cluster.
I put it back together, and bingo! The mileage is exactly what I needed. I ran the auto launcher through the modules, and the transmission included the mileage from the BCM. I didn’t see any digital mileage in the other modules, so that was it.

Read Land rover A2C83377600 Airbag with Xhorse Multi Prog

The Land rover airbag SRS Continental control unit is A2C83377600 AH22-14D374-AH. It does not have an external EEPROM, so you will have to read the processor itself.

Continental A2C83377600 AH22-14D374-AH

The module was read using the Xhorse multi prog programmer, which has a convenient connection diagram without soldering to the processor pins, and then it’s just a matter of technique.

We read the flash and EEPROM of the processor.

We loaded the EEPROM dump into the RomarioCalcs calculator for the Orange5 programmer. Calc cleaned everything up, and then re-wrote the corrected dump. The collision error disappeared, and the unit started working normally.

VVDI Key Tool Plus Program 2022 Volvo XC60 All Keys Lost

Program 2022 Volvo XC60 all keys lost with Xhorse VVDI Key Tool Plus successfully.

Decode lock with Lishi auto pick.

Remove CEM module under the instrument on the driver’s side.

Disassemble the CEM module and read data with key tool plus.

Connect 6 wires on the CEM circuit board. Also requires soldering a 100 ohm resistor on the green wire.

After you finish reading the CEM data, it’s best to tidy up all the solder joints.

Then program key via CEM dump.

Will Xhorse Multi Prog Clone PSA SID803 ECU

Question:

​I have a Citroën C4 2.0 HDI with Siemens SID803 ECU (not SID803A), and in the Xhorse Multi-PROG software, this specific ECU is only listed under OBD mode for reading MAPS.
​Since this is only a partial read, is it safe to flash an EGR, Stage1, file via OBD with this tool?

Solution:

OBD mode you can just read and write maps. Not full data.

To read full micro eeprom and flash you need to open it and read it in BDM mode.

One of our cutsomers has already cloned one like this just by opening it in bdm.

In sid803 need read in bdm and modify egr in micro not in flash.

For OBD you need ioTerminal.

Xhorse Multi Prog Current Firmware is Lower than Supported Version Solution

Problem:

Had a problem updating Xhorse Multi Prog programmer.  It said the current firmware version is lower than the minimum supported version V1.4.9.
Tried to update the firmware but failed. Any solution?

Solution:

Do a forced update.
Press and hold the RST button while turning on the power, and keep holding it for 5seconds after turning on the power.

Then Release. To see if the device can go into the firmware upgrade mode.
