This document provides information about the MKIII All Comms diagnostic tool for Range Rover L322 vehicles from 2003-2005. The tool connects via USB and OBDII port to read and clear fault codes from various vehicle systems like ABS and air suspension. It can also customize settings for air suspension, vehicle entry, and parking sensors. The tool supports ongoing additions to allow communication with more vehicle systems over time. It is meant to help diagnose problems by identifying fault codes but may not resolve physical issues requiring repair.

Description:
The MKIII All Comms is a USB enabled OBDII communications device.
This device allows the user to communicate with nearly all of the
L322 Range Rover vehicle computers. This includes the ability to read

2. and clear fault codes and the ability to configure many of the L322
vehicle subsystems.
The MKIII All Comms is very easy to use. The software and hardware
combination does require some computer or mechanical experience on
the part of the user. But overall, the software and hardware
combination is mostly hassle free and will provide years of useful
service.
The MKIII All Comms is an ongoing project. Below is listed the
current systems that the diagnostic tool and software package will
communicate with. The list will grow over time until all systems are
fully operational.

5. Notice:
The vehicle warning lights have illuminated because of an underlying
reason. There is always a reason for the fault. Sometimes the fault
condition has occurred because of a simple transient and temporary
sensor problem. In these cases, when the fault is cleared, the fault
may not return because nothing with the system is actually broken.
While unfortunately sometimes the faults can be triggered because
something is actually physically broken with the system. In these
cases, then physical problem must be repaired to prevent the fault
code from returning. In both cases, the All Comms Tool will help you
diagnose the problem and determine if expensive repairs are needed or
if just a reset of the system is needed. The reading and clearing of
the vehicle fault codes is not always the final repair step but is a
required step on the path to repairing your vehicle.
