Xhorse Toyota XM38 Only Works when Push Start Solution

 Problem:

Trying to make a Smartkey for Toyota Land Cruiser 2018, 433.92mhz FSK. I prepared a Xhorse XM38 XSTO01EN key and I programmed it with IM608 Autel. The remote worked well but the transponder only works if you pushed the start/stop button with it, If I moved the key a few centimetres away from the button, the car would not detect it, and the engine would not start.
The only problem is that for the vehicle to detect the transponder and start the vehicle, you have to stick the key to the start button, as soon as you separate the key a few centimeters, the transponder signal is lost. Why the new Xhorse key only works over the start/stop button and not works if you moved away a few centimeters.

Solution:

Change signal strength had that issue on Hilux.

Change the signal strength.

On the menu of  vvdi mini Key tool, you look at

Toyota smart Key setting, and the signal value would be reduced.

If it still not working, try the following solutions:

Sometimes a smart key generated successfully may not fully function the vehicle: remote doesn’t work, doesn’t have smart feature or even one button fails etc., which needs us to modify smart key’s values manually.

Possible reason:

Xhorse XM smart keys are universal keys, not particular for one model like Toyota Tacoma 2016, so we need to customize XM smart key to find correct values for each car.

Path: Special Function>>XM smart key customization

1. Modify Frequency

Sometimes the frequency options given to us is slightly different from that of the smart key to be programmed.

So read out the frequency “A” that your vehicle wants by Xhorse devices, then read original XM smart key frequency “B” and set “B” to “A”.

2) Modify Baud

Read key’s Baud, increase it by 400, and test if it works perfectly.

If not, add Baud again by 400 until it works well. (The last two numbers may vary automatically, which is normal.)

VVDI Mini Key Tool Firmware Upgrade Failed Solution

 Problem:

Failed to update xhorse vvdi mini key tool firmware via app and via upgrade kit on PC.

When update firmware via app, it reported error “Erase the internal chip 1 fail”.

Here is the VVDISHOP engineer solution:

1. Turn off device.
2. There is a small hole on the back of the device case. There is a button inside, press the button with a toothpick, then hold the power button.

3. Turn on device, then try to update firmware again, it should be fine.

Xhorse Multi Prog Read BMW MSD80.2 ISN Code

 Xhorse Multi-Prog read BMW Continental MSD 80.2 DME on bench successfully.

Got a “faulty” ecu from BMW, MSD 80.2 and test it on bench with xhorse multi prog.

The pinout in multi prog is wrong. Buy you can read successfully on bench the ecu with the correct pin out.

Read INT eeprom(empty) full flash, maps, ext eeprom, and ISN code successfully.

Writing work also. We have done few on bench.

Xhorse Multi prog Read BMW CAS4+ 5M48H with Adapter

We here just to inform you that Xhorse Multi Prog software V1.2.3.0 and firmware V1.2.7 fix the issue that the adapter for the CAS4 not working with the multi prog.

Firmware V1.2.7 fixed 9S12 reading issue using CAS4+ solderless adapter to decode CAS4+ (5M48H).

XDNP CAS4 adapter has two versions, V1.2 and V1.3.  The V1.3 new type of adapter with rely inside, V1.2 does not.

The old one V1.2 CAS4 adapter works perfectly.

This is a 2013 BMW 640i CAS4+. We set up the CAS4 solder free adapter with module and multi prog.

Menu: Immobilizer->BMW->CAS4 5M48H BACKUP (Adapter) option

Then read D-flash.

It is trying to decode the chip.

Read D-flash successfully. The file is huge.

We get a good read.
