OBDLink EX / Re: unable to connect to vehicle message
« Last post by STN-Manny on Yesterday at 12:55:45 pm »The EX is not just for FORScan and does not need to connect to FORScan to work.
As Shawn said, you just need to connect to AlfaOBD.
I was able to find these steps which may help you.
Detailed Connection Steps:
Prep: Insert the Bluetooth/Wi-Fi OBD2 adapter into your vehicle's 16-pin port (usually under the dash).
Pairing: Go to your Android device’s Bluetooth settings, scan for devices, and pair with your OBD2 adapter (e.g., OBDLink MX+).
App Setup: Open AlfaOBD, select the "START" tab.
Select Vehicle: Select your car brand, model, and the body computer/module you want to access.
Connect: Choose your adapter type in the app's settings (if not already set) and click the "Connect" button (car icon).
Verify: The "Status" line will confirm the connection.
If you still have issues connecting, we would suggest reaching out to AlfaOBD support.

I don't have the program loaded at the moment, but choose USB as your connection setting if prompted.
Also, be sure that the ignition is on. (Vehicle not running )
Let us know if you have any other questions,
Shawn

OBDLink EX / Re: unable to connect to vehicle message
« Last post by modified32 on March 16, 2026, 04:35:27 pm » Hi,Yes I saw that however in order for me to use the AlfaOBD program I must use the OBDlinkEX (connected to the vehicle using the Forscan program) in order for my laptop to communicate to my Jeep. Here is the page from AlfaOBD that shows what adapter they recommend https://www.alfaobd.com/supported_cars.html So I assume I would need to open the Forscan program to get the OBDlinkEX to connect to my Jeep before trying to open the AlfaOBD program correct?

OBDLink MX+ / Re: trans temp monitor
« Last post by STN-Manny on March 16, 2026, 03:19:54 pm »The OBDLink app does not have live OEM data for Acura vehicles.
You may be able to view this info using a 3rd party app such as Car Scanner ELM OBD2.
If they do not have the transmission temp PID, you can try to add it as a user defined PID in the OBDLink app after searching the Acura forums to see if anyone has been able to find it.

You will need to try using AlfaOBD for your Cherokee.

OBDLink EX / unable to connect to vehicle message
« Last post by modified32 on March 16, 2026, 10:19:40 am »Hi,I'm trying to connect to a 2014 Jeep Cherokee using a laptop with Windows 10 via OBDlinkEX I replaced the EPB (electronic parking brake) module and need to do a proxi alignment using Forscan but my issue is I keep getting the message "unable to connect to vehicle" when I try to connect the OBDlinkEX . I do have a green light on the adapter and it tells me that a connection to adapter has been established so I'm thinking the OBDlinkEX is working properly? I did check for bent pins on the OBD connector as well as all the fuses related to the OBD port,BCM,ECM ect Also tried installing the purple obd adapter inline but it made no difference Any ideas? Thanks in advance.

OBDLink MX+ / Re: MX+ reading 2016 Toyota Sequoia tire pressure
« Last post by SCysneros on March 16, 2026, 10:19:22 am »Hi J,
It is possible to do if you are using an iOS device.
The latest version (7.1.0 and newer) of the app has the ability to reference enhanced PIDs in user-defined PID equations, so a user could create a user-defined PID that subtracts barometric pressure from the enhanced PID. If you are using an iOS device, may I ask you to go to Settings > User-Defined PIDs > New and creating a PID based off the "Insert PID" function found near the bottom of this menu.
If you are currently using an android device, the app version that allows this will be available once it’s approved and rolled out.

Developer Forum / Re: ATCF command error response

OBDLink MX+ / Re: MX+ reading 2016 Toyota Sequoia tire pressure
« Last post by jsippel on March 14, 2026, 08:34:15 am »Simply providing information on how to create a user defined PID, possibly importing the PID for the TPMS reading from the enhanced Toyota stuff, and adding (or subtracting) a modifier would be helpful even if the developer doesn't want to modify the code for these special cases.
Thanks,
Jon
