Meritor WABCO Releases Latest Version of TOOLBOX™ Software for Advanced PC Diagnostic Capabilities (March 24, 2004)



Meritor WABCO Releases Latest Version of TOOLBOX™ Software for Advanced PC Diagnostic Capabilities LOUISVILLE, Ky. (March 24, 2004) — Meritor WABCO Vehicle Control Systems has announced here, at the Mid-America Trucking Show,the release of its TOOLBOX™ Software Version 5.0, offering technicians enhanced antilock braking system (ABS) diagnostic capabilities.

The software is a PC-based diagnostics program that provides technicians key information when an ABS diagnosis is under way:
•A display of both constant and changing information for the system under test (e.g.
ECU number and RPMs, respectively)
•A display of both active and stored system faults, as well as the appropriate repair
instructions
•Activation of system components to verify system integrity, proper component
operation and installation wiring

Version 5.0 updates include diagnostic capabilities for three additional
functions: hydraulic power brake system with integrated ABS (HPB), electronic leveling module (ELM) for tractors, and ELM for trailers. Also incorporated in this
update is comprehensive service and repair information for tractor and trailer
pneumatic ABS, as well as “add-on” hydraulic ABS (HABS).

One of the most important improvements to the software is the ability to download
future revisions from an FTP site. This will allow for easier, more timely access to
upgrades. For users who cannot access an FTP site, the revisions will also be available on disc.

Dennis Sandberg, president of Meritor WABCO Vehicle Control Systems commented,
“Since its inception, TOOLBOX has proven itself to be a beneficial instrument in
keeping vehicle downtime to a minimum. Version 5.0 incorporates some of our
advanced ABS functions and provides technicians with even more valuable diagnostic information.”

Originally developed in 1999, the software has made significant in-roads in streamlining ABS maintenance procedures. Sandberg added, “As ABS technology
has advanced, TOOLBOX functionality has followed suit. We will continue to grow the
software’s capabilities keeping maintenance as trouble-free as possible for the service
technician.”
