MULTIPLEx INSTRUMENTATION
Kenworth utilizes Multiplex instrumentation and wiring to continuously improve our quality and the capability of our trucks.
Multiplexing utilizes the industry standard Society of Automotive Engineering (SAE) J1939 data bus to send multiple
signals over a single twisted pair of wires instead of individual wires for each function. The advantages are fewer wires,
sensors, and connections that provide greater consistency, improved reliability and the ability to use ESA to troubleshoot
the instrumentation. The following information is provided to increase your awareness about the Kenworth product, it may
be useful in installing telltales (warning lights) and gauges and coordination with other installed equipment .
Don’t cut or tap into green/yellow twisted pairs. Only use “T” connectors, and only add
approved J1939 components with validated software.
