Looking for a good code reader. Would like it read and clear codes and possibly show some live info as well. Dont want cheap but inexpensive would be nice.
I have tried a couple of the ELM327 so far and have not been able to get them to connect, did you have to do anything in particular to get it to connect? I am attempting to use with the free Torque app.I use an ELM327 bluetooth adapter ($10 or $20 on Amazon) & the Torque app on my Android cell. Took a little work to get it all setup, but not only can I check & clear scan codes, then Google them from the phone, but I can setup gauges on it to monitor all kinds of stuff.... big one for me was the trans temp.
I'd upgrade to something like an SCT ITSX programmer if I had any faith that I couldn't screw up my ECM. Would be cool to run separate performance, towing & economy tunes on it.
what app is it exactly that you use? i dont see a "torque free"I see that on my Torque Free App, upon startup it tells me (upper left hand corner) "connecting to OBD2" and then switches to "adapter not found" (because I am out of range). What messages are you getting there when you start up Torque Free. Those could be key.
Correct. Trans temp is an enhanced GM PID. Also, in Torque Pro you have to turn on access to the GM PIDs. It's only $10 for Torque Pro.ah. so the free one wouldn't be able to do trans temp?
The 1500's switched over to Canbus for the drivetrain only in 2006. I don't believe ANY GM vehicle was Canbus before 2006. GM trucks switched over to all canbus variants in the truck in 2007. Not sure about the 8.1, they may have waited on them until the 2007 model year to go to canbus. All auto manufacturers were required to be CANBUS by 2008.Can't tell you for sure if Torque Pro does trans temp or not in your vehicle. I would guess so. A lot of these little Bluetooth apps have GM PIDs that may or may not work for a specific vehicle. Only one I know that filters the GM apps is Dash Command.
For your 2003, your best bluetooth bang for the buck is Car Diagnostic Pro. Will read/clear codes for multiple systems like HVAC, SIR, ABS, etc. Has a full bevy of GM enhanced PIDs (unfiltered of course). I can confirm it will do trans temp on my 2004 Avalanche. However the enhanced GM PIDs on this app end at the point when GM adopted the CAN OBD2 protocol. They started in 2003 with some models, and by 2008 were 100% CAN protocol. It will still read/clear codes and display some info but not the GM enhanced PIDS using CAN on the newer vehicles. These were never developed by the app maker. Instead he concentrated on Ford and Nissan enhanced PIDs with the CAN Protocol and ignored GM. So I would guess somewhere 2005-2008 GM switched over the Avys to CAN. I do believe the 8.1 engines were first.
For bluetooth on the CAN protocol vehicles up to 2009, I recommend Dash Command. Past 2009 I have no idea what works and what doesn't.
Weird that mine will not connect, can you post link of where you bought yours?I have an ELM327 and it works great with my 09 with Torque.
I just got an Otofix D1 bi-directional scanner. Works well and is user friendlyLooking for a good code reader. Would like it read and clear codes and possibly show some live info as well. Dont want cheap but inexpensive would be nice.
