We have very precise tools for this job, but you can still nail this test by improvising a fine paper clip or such. We’re using our ability to feel the difference in tension from one terminal to another. We’ll place a fine metal tool between the pins and feel the resistance when we remove it. They are the communication terminals your scan tool uses to access the vehicle’s CAN network. Pay particular attention to terminals 6 and 14. Note: not every DLC slot will contain a terminal. Well, front probe the pins and compare tension.Ī visual test comes first. This causes resistance and often is the root cause of scan tool communication issues.įor this test, we’ll do what I said was rarely a good idea. Wear and tear and front probing cause the terminal legs to lose tension. Your vehicle’s DLC terminals are known as female terminals. A visual test may reveal the issue, but more likely, you’ll need to perform a pin drag test.

How to check the scan tool plug?Ĭhecking your vehicle’s socket is a little more work but not much. This type of repeated activity will eventually cause scan tool pin wear or damage and spreading of the vehicle’s female OBD socket terminals. Reaching into a vehicle, blindly fitting or pulling the scanner cable is a normal everyday occurrence.
In a long-winded way, I’m saying your vehicle’s OBD connector, also known as the DLC (Datalink connector), may be damaged from possibly years of OBD scanning and, dare I say it, “Front probing.” That’s not to say we disrespect kit or customers’ vehicles, but working on a workshop floor is all about speed. I’m a mechanic, and while we’re known for our MacGyver-type skills, we may not be generally prized for our finesse.
So what’s the problem with the OBD plug/socket? Number one, it only takes a few moments, and number two, while not being the most common cause of a scan tool that won’t communicate, it is by far one of the easiest fixes. This may seem like a simplistic answer, and you are correct, but it’s worth exploring for two reasons. A blown a fuse is often the cause of a scan tool that simply won’t power up. If, however, your scan tool won’t even power up when you hook it up, then check out this post “OBD scanner won’t turn on” it covers the simple fix in detail. When writing this post, I’ve assumed your scan tool powers up when you plug it into your vehicle’s OBD port, but it just won’t connect. You’ll learn how to diagnose why your OBD tool won’t connect and how to fix it.

I just want to be able to install a tablet to use for off-road nav and have it run Touchscan or Torque as well so I can monitor sensors and the like while I'm in the woods.In this post, you’ll learn about each of the common reasons an OBD scan tool won’t connect to a vehicle. If it works that's really all I care about. I may just order the BAFX dongle: and give that a try and return the other one.

I just really wanted to use this one in particular because it has an on/off switch so I could just leave it in the car, plus it's smaller so I won't kick it when it's plugged in. I may try it with some other cars and see if it gives me the same results as well.

If so it might just be a bunk BT OBDII scanner that won't work on the ISO 9141-2 protocol which if I have read correctly is the one for my car.
I think I'm going to stop by Advance or another car store on my way home from work today and see if their scan tools can connect.
Scan master elm no connection to ecu Bluetooth#
I have a bluetooth stereo HU in the 4runner that my phone is set to connect to, but I have the settings right in the apps so that it connects to the "OBDII" device and isn't trying to talk to the ECU through my stereo. I also tried closing all the programs and opening each individually and it still won't connect, including a hard reboot of my phone as well. It wouldn't connect with that app, so I installed Torque and tried that as well, neither would connect to my T4R. When I connected to my wife's Rogue originally I only had TouchScan installed. Did I get a lemon?Ħ2k miles, 265/75-16 BFG TA-KO's, intake silencer delete, I've logged other cars (DSM's, Subarus) with other OBD type devices and all I want to do is have some extra parameters on my phone or a tablet available.Īm I missing something here? I've even tried forcing the app to use various com protocols individiually, and running it in 'auto' mode to detect which communication protocol, nothing works. Is there something else I'm missing? Do I need to try some of the custom init strings I've seen a few threads of on other forums? It connects just fine to my wife's 2008 Nissan Rogue, so I doubt it is the actual unit itself. When it tries to connect to the ECU it errors out and asks if the ignition is on/etc in Torque (free) AND with TouchScan apps. The unit gets power (lights turn on), and my phone connects to it via bluetooth just fine. I checked the OBD fuses and they are all good. Hi guys, first post but long time lurker here.
