If you've experienced the DPF warning and going to Limp Mode then first get the ECU updated at the dealer/service with
Update: RRT 14-104 (TSB 18-019-14a) under warranty.
This updated mentions a fault with software: DTC P2463 which is the DPF full warning / limp mode.
I'm using a ScanTool OBLink MX Bluetooth adaptor with an Android smartphone
ScanTool.net LLC - Scan Tools, PC, iPhone, & Android based OBD-II (OBD2) Interfaces, OBD diagnostic software
It's not the cheapest. Actually, is one of the most expensive.
The MX version has a feature where it powers down after the interface is off, so i can just leave it in there.
(The OBD port on the car is always powered straight from the battery)
I purchased from the Aus agent they list on their website.
OBD-II Car Scan Tools | Australian Robotics
They're on ebay for similar $$$.
If you are planning to use an iPhone or iPad you would need the MX wifi
version instead. The iphone's BT isnt compatible with the BT dongle (Apple's BT is crap, too slow apparently).
Note: Having the MX wifi version and switching your iphone/iPad to wireless network mode unfortunately might mean 3G/4G data the GPS functionality doesn't work for the mapping features in the apps.
There are plenty of other cheap alternatives in Ebay for only $10-15 or so but .......with possibly some compatiblilty or power/battery issues it would be annoying so i went for the expensive one.
The ScanTool OBDlink app for smartphone is what i've been using. It only works with this particular brand of adaptor. They also gave me a PC based program & license.
"Torque" is another good app for Android and iPhone, works with any adaptor. Paid version is about $5 and has lots of features. "XtRmn8" on the forum here I think uses Torque.
I've tried a few others "Dash-Command", "OBD-facile"(french) etc.
I've found that the Jeep only displays some of the standard OBDII PID's that the apps support. Jeep does not have all of the sensors connected to the ECU that we can read either.
OBD-II PIDs - Wikipedia, the free encyclopedia
The app I am using and also "Torque" app allow you to enter custom parameters to monitor and display as they may not be in the list that comes with the app. You just have to find the data to monitor and the work out the maths to display it correctly.
I've searched on the internet looking for ways to monitor the exhaust temps and DPF condition and managed to work out the reading which seem to give us a normalised DPF % loading value, which at least gives some warning of when it might regen (or not).
So far I have tested some of the other standard OBD values that the Jeep supports but there are several more which I'm attempting to reverse-engineer.
a PM sensor?(if there is one), Fuel pressure &temp. VGT control and EGR for example.
