You can find the oil life percentage remaining using AlfaOBD.
OK, so AlfaOBD learning-curve time for me. First time I've fooled with it. And already I'm lost, even referring tot he fine AlfaOBD instruction online.
I've got the PC version of AlfaOBD on my laptop -- looks like you're using a cell phone version.
I hooked up the PC to the Trailhawk's OBD2 port using just my OBDLinkEX cable:
Turned the ignition on (not the engine).
Clicked on AlfaOBD, and allowed it to update.
On the initial screen it was already showing JEEP and RENEGADE (BU). I chose the ENGINE fuction, and got this:
So how do I know which ECU I have? Obviously not the diesel ones, or the Tigershark ones (with my 1.3T engine).
With all the others, when I click "Connect," all it gives me is a screen asking me to choose my Bluetooth device.
What am I missing? Do I need my "Grey adapter" for this?
* EDIT *
I went back and played with it some more.
First, I went into "Advanced mode," and found that the Interface was set to Bluetooth. So that would explain why it was trying to Bluetooth-connect.
So I set it to USB OBDLink SX/EX. COM3 is the only COM Port choice:
But no matter which ECU I tried to "Connect" to, I kept getting the same error:
Whether ignition in RUN or engine on. With or without the "Grey adapter."
OBTW... I realize my 2021 Trailhawk is a BV model, not BU. But BU is the only Renegade choice on the screen...
