OBDWiz and STN1110
« on: November 02, 2011, 09:37:42 am »
Hi,

I am tried connecting the STN1110 to the OBD port and wanted to check if I could see CAN bus information through the OBD port on Toyota RAV4 2006 Gasoline vehicle. When I do an AutoDetect OBDWiz fails to detect any protocol when connected to the toyota RAV4. However it does detect the COM port which it is connected to. Even commands like AT RV (ST RV) would not give any reponse.

So I tried connecting STN1110 to another car. VW Jetta 2003 Gasoline. OBDWiz detected the COM port (laptop end) and the protocol (OBD end) as ISO 9141-2. It also detected 2 ECUs 1A with 7 PIDs and 10 with 20 PIDs. When I selected any one of the ECUs, it would connect for a short period of time (2-3 sec) and automatically disconnect. In this, AT RV returned 13.3 V which is what I would expect.

I also tried it on Mercedes SLK 280 roadster Gasoline. Everything works like a charm here. The protocol detected was ISO 15765-4 (CAN 11/500) and I was able to see the entire CAN bus information (available on OBD2).

I thought it could be a OBDWiz issue and so used MyTTY (like hyper terminal) and connected to the COM port. I saw the same behavior as mentioned above on all the 3 cars. I checked the pin configurations of the OBD to DB9 connectors and they are the same. What I want is to monitor all the CAN frames (AT MA or ST MA) or anything equivalent. I do not want to poll information to get vehicle speed but be able to monitor the CAN bus information at its baud rate (eg 500 k baud).

Kindly help me figure out the problem.

Regards,
axs

CANUSB F7001 from EasySync vs STN1110
« Reply #1 on: November 02, 2011, 09:52:04 am »
Hi,

Previously I had bought CANUSB f7001 from EasySync. I connected one end to the OBD port and the other end to the laptop and I was able to read all the information on the OBD port (50 messages) on a 2006 Toyota RAV4 Gasoline car. I didnt have to poll or read PIDs for information.

Now I have a STN1110 and am trying to do the same. On connecting the device and selecting/ searching for the correct protocol, still I was not able to get any information from the OBD port. I have no experience in using STN and am new to this. So, I tried using OBDWiz and still was not able to read any information from the 2006 Toyota RAV4. The pin connections are connect, I have verified it. I would assume AT MA or ST MA command will help in monitoring all information on the OBD port.

Please help me get a better understand of this device and also in getting started with STN device.

Thanks,
axs

Hi Axs,

Can you please post logs of the RAV4 and Jetta?

To create a log, go to Diagnostics->Raw Data and click "Always Collect" if there is not a green check mark next to it, then connect. Copy/paste the data into your next post.

What country were the vehicles purchased in?

Thanks,
Jason

For the Toyota RAV4 2006 Gasoline -

The connection itself wouldn't establish. I do not have any logs from this car. OBDWiz does not even allow me to go to the log sections. I did manual connection and also Auto detect and connect options. I have checked the pin configurations and also voltages on the OBD port end. They look fine. I even connected another tool CANUSB F7001 from EasySync and checked on the hypertermial to find the below information on Toyota RAV4 (which is what I also want from STN1110) -

Merc SLK 280 Roadster 2007 model Gasoline -
I only got my hands on this car for a day. I do not have the OBDWiz log for this. But using STN1110 and checking on the hyperterminal, I was able to get this (again this is what I want and I could get it with STN1110) -

BUFFER FULL

==========================
With the EasySync, I get a continuous input of data without a buffer full, but with the STN1110 I get a BufferFull. This is another concern and I can take it as a new post. But my main concern is that STN1110 is not being detected on the car which I am using to test (Toyota RAV4).
For all the good reasons, we plan to opt for STN1110 and go towards bulk order but the road block currently is that we are not able to verify that we can use this device and OBDWiz on all cars.

Sorry for the long post and thanks again for your reply.

I'm assuming you're using a homebuilt interface?

The first issue, <DATA ERROR on the 2003 VW Jetta is probably caused by dirty power (to the point where the interface disappears from the system). You can try to fix the issue by adding more capacitance, or even adding a proper power filter.

The second issue is unrelated, it has to do with how STN1110 interprets CAN messages. When you tell it to automatically detect the protocol, it tries legislated CAN first (ISO 15765), but the messages are actually raw CAN (ISO 11898). Do "ATDP" after "ATMA" in your example, and tell us what the protocol is.

Hi Vitality,

Interesting that you said that it was a homebuilt interface. I checked all the connections and they are all fully connected. The OBD2 port also seems clean and I am able to read data using EasySync's CANUSB F7001. I have checked it for both the cars VW Jetta 2003 and Toyota RAV4 2006.

And for the second part. This is what I get from both the cars -
VW Jetta - Protocol detected: ISO 9141-2 (5 baud init, 10.4 Kbaud)

Toyota RAV4 - I am still not able to read another from the car using STN 1110 with and without OBDWiz. However as I mentioned in my previous note, I am able to read the CAN bus information using EasySync's F7001. Below is what I get with STN1110 and OBDWiz.

Version: 2.7.1.2

System.TimeoutException - The operation has timed out.

My last important part. I really what to know what this is...
Using 2 separate devices on 2 different cars I was able to get this information.
1. EasySync 7001 on Toyota RAV4 2006

208 00 20 00 00 02 5C 00 00


The first three digits (after t in the first case) are the HexIDs or MsgIDs from CAN bus. The remaining are data packet size, data bits etc etc.

What I got from VW Jetta 2003 using STN1110 was - (when I hit ATMA)
01 0C 1: [48 6B 10 41 0C 0C 3D 59 ]
01 0D 1: [48 6B 1A 41 0C 0C 35 5B ]
01 0C 1: [48 6B 10 41 0C 0C 21 3D ]


Why this difference? The data from Jetta does not seem to be like a normal CAN-bus message. It seems like a diagnostic information.
How can I get the information with the HexIDs? I actual CAN bus information?

Any answers on this will really help me understand the whole thing much better.
Thanks a lot in advance and hoping to get some information.

axs,

You lumped a whole bunch of issues into a single post. Untangling the meaning from the mess is a challenge. Consider focusing on one problem at a time.


Interesting that you said that it was a homebuilt interface. -- so is it, or is it not?


System.TimeoutException - The operation has timed out. -- Have you tried cleaning up the power (e.g., add caps) as I suggested?


What I got from VW Jetta 2003 using STN1110 was - (when I hit ATMA)
01 0C 1: [48 6B 10 41 0C 0C 3D 59 ]
01 0D 1: [48 6B 1A 41 0C 0C 35 5B ]
01 0C 1: [48 6B 10 41 0C 0C 21 3D ]


You didn't use ATMA to generate this, it looks like part of OBDwiz log.


Why this difference? The data from Jetta does not seem to be like a normal CAN-bus message.

Because the protocol is not CAN, it's ISO 9141-2.

Hi Vitality,

Sorry for the any confusion caused.
Yes it is a homebuilt interface. The sockets, ports are cleaned and the required caps are added as you suggested.

I have the two cars (2003 VW Jetta and 2006 Toyota RAV4) which I am checking on, and STN1110 hasn't worked on both. So, I will be listing both the information below. I have used both OBDWiz and MTTTY (which is like hyperterminal).

I again did what you had suggested -
ATDP and then ATMA

For 2003 VW Jetta -
This is what MTTTY shows
> AT Z

ELM327 v1.3a
>AT DP
ISO 9141-2
>AT RV
13.7V
>AT MA
>AT Z

ELM327 v1.3a
>AT DP
ISO 9141-2
>AT MA
>

So when I did ATDP, it would show the protocol, but wouldn't show anything when I did ATMA. It would also show the current battery voltage reading with ATRV.

This is the raw output from OBDWiz

Post your schematics, please. My suspicion is that you are powering STN1110 from the OBD port, and the RAV4 has a blown fuse. Check the voltage on pins 5 & 16 of the DLC, it should be roughly 12V. If you read zero, check the cigarette lighter fuse.

Hi Vitality,

Thanks for your help. Actually we are using the SparkFun board http://www.sparkfun.com/products/9555
The voltage on Pin5 & 16 of DLC was reading a 0, but the cigarette lighter was reading 12+ V.
Toyota RAV4 has a separate fuse for OBD port and a separate one for the cigarette lighter. We checked the fuses to fine, so went tracing the pin16 wire and somewhere inside we found that the wire was cut, we replaced that wire and were able to see data on Toyota RAV4 also (data at the end of post).
I also checked and found that the other portable device we were using was powered by the USB port rather than the OBD port and thats why we had no problems with the RAV4 and that device till now.

Thanks for all your help. Now the first step is over, we are able to read CAN-bus data using STN1110 which in itself is a good news for us.
As you will notice from the data, there are 2 big concerns which I still have -
1. Buffer Full
2. Data Error

I will post this concern as a new post, and this post can be closed.

Thanks once again for your help,
axs
