My friend purchased and ELM327 generic adapter and the current version of Torque. I’ve been playing around with it and am very impressed. I guess he got one of the “good” adapters from China, because we haven’t had any issues so far. I’m considering purchasing the ELM327 and Torque, but have a few questions. I’m a mechanic for a living and would like to be able to use Torque to actuate the electric fans or fuel pump… for testing purposes. I emailed Ian to see if Torque would ever support this function and he told me that it’s possible with the current version, you “add display” pick “Push button” and then you long press on the “send command button” and it gives you the option to “set command to send” It says “Enter raw OBD command(s) to send:” and there is a test command button.

What data goes in this box? I’m currently working with either a 98 Chev K1500 5.0 or 2004 GMC Yukon 5.3

Any help or info would be much appreciated.

I attempted to do this but did not get so far since my vehicle is not capable of comprehending the commands, for some reason :/

You will need to send the OBD commands for activating the fan

If this includes needing to activate the enhanced diagnostics mode as well then you will need to send that relevant command as well

The push button ‘send command’ can send multiple commands at once (seperated by a line break), so you could send ELM specific commands, or direct OBD2 commands – it’s simply a case of entering the relevant information as per the ELM327 data sheet (think of the ‘send command’ button as a terminal that sends the data in it when the button is pressed)

Help!

Can you please give an example OBD command data for Using the “Send OBD command” with the “Push Button” Display widget please ?

Are command characters required before the CAN message data?
Is the Data entered in HEX format ?

This will help us to know where to start with using this mysterious feature. Thanks

Ian, is there a way to also see the ELM327’s response to each command sent to it or to the OBD bus? It might be useful sometimes to see the response too.

The usage of Torque Pro could really takeoff if this was clear how to use the SEND button to send a CANbus message.

obd is standard

communication in the car is far from standard even if it use the same bus

but it’s not impossible to do

sometime you just need to sniff the bus to see what is sent by the device and the reproduce the data …but it is time consuming if you start from scratch

You normally have more chance finding the info on a forum specific to you car
