Civic 2010 OBD

[zeesh1979]

Hi Guys,
I was working on a python project and used a famous package to access the ODB. I ran several commands but most of them said my car doesnt support while others like speed, rpm and throttle etc are fine. any advises from you guys about this? i tested them on my Civic 2010 (Saudi arabia). Below are logs showing PIDs and other details:

Issue the commands manually using a Terminal program. That way you can isolate if this is the problem with the adapter, the package, or your script.

 

[zeesh1979]

i did it using a terminal app on android and below are logs (getting no data for these commands)

5E94 //fuel rate
NO DATA
5C92 //oil temp
NO DATA
5181 //fuel type
NO DATA

below is output of 0100
0100

Are you using Elm327? You probably already knew this, but here are some docs
https://www.elmelectronics.com/wp-content/uploads/2016/07/ELM327DS.pdf
https://en.wikipedia.org/wiki/OBD-II_PIDs

I'm not sure why you have 2 lines of replies to the 0100 command. You should only get one line.

And not sure why is fuel rate 5E94? Shouldn't it be 01 5E? 5E in base16 is the same number as 94 in base 10.
>>> 5E94 //fuel rate

To query if 01 5E is supported, you need to send 01 40. This will query if PIDs 41 thru 60 are supported.

I also noticed you use 0114 for O2 bank1. 0114 is "Oxygen Sensor 1". O2 Bank 1 is Service 5 not 1.
>>> [obd.obd] 'b'0114': O2: Bank 1 - Sensor 1 Voltage' is not supported

If the PID is supported, then "NO DATA" could mean the response timeout is set too short. You need to set the timeout to a longer value.

If it's easier for you to use do this on a PC, "teraterm" is a very nice terminal program for Windoz.

Oh ah, see if you can read the same data with the Torque app

Thanks alot. its my bad. actually im kinda new to this OBD. when i was looking ta the commands table, i didnt notice the 1st column is hex and 2nd is dec, i just combined them. i will check correct commands and then see how is the response. regarding 0140, i already ran 0120 and 0140 sometime back and it showed me:

0120>
41 20 80 1D B0 01
41 20 80 00 A0 01
0140>
41 40 CA C0 00 00
41 40 7A D0 00 00

i am working on python, i will run these commands again after increasing timeout period
