Here comes the solution to Xhorse multi prog BMW CAS3 chip crack failed problem.
Problem 1:
Read CAS3 0L15Y with multi prog, it says chip crack failed and asks to increase the voltage.
Problem 2:
Read and write a CAS3 from BMW 116 2007 model with multi prog…….. finally it manage to read and write (to remove ELV) but with problems. It starts reading the eeprom and it read it just fine, the tool works great with this… but when i start to read the flash, the tool couldn’t read it and suggested me to increase the voltage, I increase the voltage and the half of my attempt to read the mcu the multi prog couldn’t do it.
Solution:
Bad connections. You need to clean off the coating bmw put on the pcb board and then it will work.
You will get chip crack error if a pin isn’t making a perfect connection. You can use a special pen that removes the coating on it.
Multi prog reads with no problem. Do not connect XCLS screen and check connections one of the pins is incorrectly marked in the xhorse description.
If pin is correct, then try to increase voltage to 4-5V, try again.
You can also use the XDNP11GL CAS3 solder free adapter.
Feedback:
Done, one pin has bad connection. Redo every solder.
After reconnecting all needles tried again and succeeded.
Xhorse Multi Prog read and write Hyundai KEFICO MEG17.9.13 ECU on bench successfully.
Select Hyundai->Kia MEG17.9.13
Check wiring diagram
Connect Multi-prog with ECU following the pinout.
Read INT eeprom
Read INT flash
Back up data successfully.
We are going to do IMMO OFF.
Upload the modified IMMO OFF file and write flash.
Multi prog will ask you to do a checksum correction.
Checksum calculation successfully.
Write flash until finished.
Problem:
Trying to read a Mercedes W906 9S12DT256 with xhorse multi prog, it said not connect to the device and will not read mcu. Any advice?
Solution:
First of all check the connection. If the connection is fine, it can be driver issue.
Win7 system have to install driver manually.
There is a ‘usb_driver ‘ folder in multi-prog software folder.
Install USB driver according to your system (32 bit or 64 bit).
Then choose device type as USB Serial (CDC), press Install Driver
Check computer device manager see if USB driver is installed properly.
Run multi prog software again.
It is a processor MC68HC08AZ32. Try to read the processor from Security Byte using two programmers, Xhorse Multi Prog and UPA-USB S.
See which one is better at this processor.
UPA S:
Processor blocked from reading, read each cell from EEPROM area as AD
Everything works better when connected to a computer.
Attention!!!
If you do not have a special password to read data from the processor, use Multi-PROG, which automatically finds the Security Byte in the MC68HC08AZ32 processor.
Xhorse Multi Prog programmer read Mercedes Benz Bosch EDC17CP01 ECU on bench successfully.
Quick search EDC17CP01 and check wiring diagram.
Connect multi prog with ECU follow the pinout
Read INT EEPROM and save.
Multi-prog read INT eeprom in 1min 24s.
Read INT flash and save.
Reading flash takes longer in 3min 12s.
