Blocked ELM request :2E 6C 1C F8
It seems that you are not in expert mode, so the request is for your security blocked...
There are other closed issues about this problem, please read them.
from ddt4all.
You may need to increase CAN timeout also
from ddt4all.
Thank you your suggestion. I had screened the closed issues and tried increase the CAN timeout to 1000. However, it still not work
The message "Blocked ELM request" still there and I'm sure i have turn on the Expert mode with "After Sales" option.
I'm using China ELM327 however, I only can connect with speed 38400, all other speed will show "No ELM is available" or "Window Error(5, 'Access is denied.')
I noticed that you had released a per-released version v1.1, i will have a try if no other way.
I also suspect the Antivirus program block ELM request, it is possible?
from ddt4all.
Do not attempt a write operation while there is "NO DATA" in the read parameters, it is normal to use 38400 bauds to connect ELM. Check if there's a PIC18F25K80 chip in the ELM.
Try to benchmark your ELM too.
And no, antivirus cannot block ELM request

Is it good enough for the ECU write ? Thank you.
from ddt4all.
It should be enough. But it doesn't mean your ELM has no problem.
Try to connect to other ECU (on the vehicle CAN) to check if it's working correctly.
from ddt4all.
Can you provide log files for analyse ?
from ddt4all.
Here is the log file. Sorry the data may be mess due to i try write multiple times. Thank you for your help
from ddt4all.
You have a lot of CAN ERROR reported by ELM meaning (ELM doc) :
CAN ERROR
The CAN system had difficulty initializing, sending,
or receiving. Often this is simply from not being
connected to a CAN system when you attempt to send
a message, but it may be because you have set the
system to an incorrect protocol, or to a baud rate that
does not match the actual data rate. As with BUS
ERRORs, the CAN ERROR might also be the result of
a wiring problem, so if this is the first time using your
ELM327 circuit, review all of your CAN interface
circuitry before proceeding.
I suggest to check your wiring first. Have you tried to connect on the vehicle bus (ECM for example) ?
from ddt4all.
Would like to appeicate your help. I can now connect the car and able to update the values. I just had wrong wiring before. Thank you and please feel free to close this ticket.
from ddt4all.
👍
Great, so, closing ticket
