Program Tire Size and Read/Clear DTCs in your Jeep/Dodge using an ELM327 device

PARscan is used with a bluetooth ELM327 diagnostic tool to read/clear Diagnostic Trouble Codes (DTC) and updating vehicle data on several different Jeep, Dodge, and Chrysler vehicles with a primary focus on the Jeep Wrangler (JK) and Dodge Ram.

Key Features:

Dodge Ram Trucks 1500/2500 (2006 to 2011)

Jeep Wrangler JK (2007 to 2016)

Dodge and Chrysler Minivans (2008-2010)

It may work on newer vehicles and other makes, such as a Grand Cherokee 05+, Jeep Patriot, or Jeep Commander. If it successfully reads data for these vehicles please let me know.

This is a Beta Release!! Please provide feedback on what works and what doesn't work.

PARWidgets is limited to vehicles using a CAN bus interface. Any CAN-based Chrysler/Jeep/ Dodge vehicle might be compatible. In general, if it can read and display the programmable information (i.e. tire size, axle ratio, tire pressure limits, etc.) properly then it should be able to update it.

A low cost ELM327 clone can be used. The clones tend to be very slow. Writing Tire Size and Drivetrain Ratio information to the TIPM can require multiple attempts. A high quality ELM327 compatible device is recommended.

DTCs can be read and cleared from the following modules

Powertrain Control Module

Totally Integrated Power Module (i.e. smart fuse box)

Wireless Control Module / TPMS

Steering Wheel Angle Sensor Module

Radio

Amplifier

Sway Bar Disconnect Module

Anti-Lock Brake Controller

Instrument Cluster

WIFI ELM327 adpaters are not supported at this time.

The APP will stop functioning on 3/27/2018. I will extend the date with updates as needed.
