Ford Transit - North America

[anthonysecco]

Hi WiCAN Friends,

I have a 2021 Ford Transit in which I'm using WiCAN to connect to my RV's home assistant via MQTT. I was able to get the standard PIDs working using 6- ISO 15765-4 (CAN 11bit/500K).

In my next step, I would like to build a custom profile to pull in Ford specific sensors. I've scoured the Internet and have assembled a list of what I believe are workable PIDs with their respective expressions. It's unclear to me whether these require specific "init" values or not.

Nonetheless, I've used the custom PID in the GUI of v4.04 without any luck. It seems regardless of what I enter, I'm not seeing anything pop up in MQTT explorer. Here's an example:

It seems to me that I either have the wrong PID or missing a required init to pull this data.

From what I understand on this page, I need to setup ELM327 on BT with CarScanner, isolate my desired sensor, and capture the logs to know what it is I need to use for init and PID.

Do I have that right? If so, I'll go through the process of building a profile for a Ford Transit (North America).
 
Thanks!

@anthonysecco please follow the instructions in the link to export the logs for the specific sensor.

For your custom PID to work you need to set the proper header and address filter commands in PID init, we can find these values in car scanner logs.

Thanks - I went through the process and got a number of additional PIDs using Car Scanner. Here's a sensor of interest:

>221E1C 7E805621E1C012A

This should be Trans Temp with the expression:

((signed(A)*256)+B)*9/80+32

The init is ATSH7E0. I believe the header is 7E8 with a value of 65 F. Mind you this was a cold start.

I've attempted to add this as a custom PID, but I'm unable to find where to add the header details. In any event, I haven't been able to get anything to show up on MQTT explorer.

I've added ATSH7E0 but that didn't seem to matter.

I feel like I'm missing something basic. Once I sort that out, I'll have a number of other sensors that could of interest to justify a vehicle profile. Thanks!

I've probably spent more time than a care to admit fidgeting. It's probably something related to the initialization. I've combed over the logs and it's not clear to me the sequence. It's something like this, but it still doesn't produce the data:

ATZ;ATE0;ATH1;ATSP0;ATS0;ATM0;ATAT1;

I've even connected to the ELM327 protocol mode in raw on a terminal from my PC and issued commands. I can access some PIDs, but not 221e1c like car scanner could. It always came back 'no data'. Time to take a break. Anyone who can parse the logs and enlighten me to another initialization string would be immensely appreciated.

[meatpiHQ]

You should set the protocol to 6. So instead of ATSP0 it should be ATSP6. WiCAN doesn't support auto protocol. Also note that a ; is expected after every command and at the end of the init string.

[anthonysecco]

Thanks for sharing those. Makes it a little easier I suppose.

No joy with ATSP6 under the custom PID menu.

I've taken a new data log with car scanner to get exactly what I'm looking for to see what the parser shows.

Second-to-last PID
{ "request": "221E1C"", "response": [ "05621E1C0407" ], "header": [ "7E8" ] }

Last Commands
{ "command": "ATSH7E0", "response": [ "OK" ] }

Commands (AT/ST/VT)
[ { "command": "ATSP0", "response": [ "OK" ] }, { "command": "ATAT1", "response": [ "OK" ] }, { "command": "ATAL", "response": [ "?" ] }, { "command": "ATST64", "response": [ "OK" ] }, { "command": "ATSP0", "response": [ "OK" ] }, { "command": "ATAT1", "response": [ "OK" ] }, { "command": "ATAL", "response": [ "?" ] }, { "command": "ATST64", "response": [ "OK" ] }, { "command": "ATSP6", "response": [ "OK" ] }, { "command": "ATAT1", "response": [ "OK" ] }, { "command": "ATAL", "response": [ "?" ] }, { "command": "ATST96", "response": [ "OK" ] } ]

The Commands (AT/ST/VT) section is quite redundant. I took it at face value and entered it exactly with ; separation. No luck either.

Based on what you observe above, would you construct the custom init differently?

[anthonysecco]

I've limited to init to the following:

ATAT1;ATST64;ATSP6;ATST96;

Alas, nothing in MQTT. Standard PIDs work if I have them enabled.

If I feed these inits and the PID into the terminal I do get valid data back

Clearly I'm missing something. Thanks again for the engagement.

[meatpiHQ]

I think you're almost there :)

The expression is incorrect, the format you're using is not supported. It has to be something like ([B4:B5]*9/80)+32

[anthonysecco]

I've made significant progress. I've logged the serial port and used FORScan to pull data on a sensor similar to the Car Scanner procedure. Anyone with a Ford can do that to get specific information available on their vehicle.

I have no issue pulling data from the PCM. There's another module BCMii that has tire pressure data. From FORSCAN, the response looks correct, but when I pull it from WiCAN AutoPID I'm not getting the expected response. Once I get this sorted, I'll provide a json for a Ford Transit that can be posted to the project.

Second-to-Last PID

{ "request": "2228131", "response": [ "6228130490" ], "header": [ "6228130490" ] }

Expression:
((((256 * B4) + B5) / 3 + 22 / 3) * 0.145) / 14.504

Last ATSH
{ "command": "ATSH000726", "response": [ "OK" ] }

I'm thinking there's a header of '726' being sent to WiCAN but I don't have logs to prove it. FORScan may have an init commands that chopping that off, not really sure.

What's really gnarly is the AT/ST/VT commands. I simply have the following

ATE0;ATL0;ATH0;ATR1;ATST32;ATSP6;ATCAF1;STCCFCP;ATSH0007E0;STCAFCP7E0,7E8;

In my FORScan log, I have this mess:

I have a sneaking suspicion, though no hard data to prove it, that maybe the WiCAN I have doesn't support the required instruction sets.

I've pre-ordered the WiCAN Pro so time will tell. Counting down the days until March 19.
