Western Star trucks now feature a redesigned cab front wall that offers updated system diagnostic capabilities, streamlined air and electrical routing for improved accessibility and serviceability, and a reduced component count.

Inside the truck cab, a ‘dead pedal’ has been added to provide an ergonomic foot rest for additional driver comfort and to protect the air line connections. The new design allows key electrical connections to be serviced from the ground without having to remove additional front wall equipment.

Body builders will appreciate the improved access to the truck’s electrical system along with new user-friendly electrical and air schematics that aid in their body installations, the company says.

The electrical system has been updated to a modular design concept that will improve serviceability by making it easier to isolate individual electrical circuits and to diagnose issues in the field. Communications capabilities now include SAE J1587/J1708 and J1939 standards with
diagnostic access via a nine-pin connector under the dash. The improved electronic system diagnostic capability is standard with the new design.
