New instrumentation and driver info center on Model 387

Peterbilt’s Model 387 tractor has been enhanced with new standard multiplex instrumentation and the addition of a "state of the art" driver information center. Drivers now get real time information to improve the truck’s fuel efficiency, performance and serviceability.

There are new stylized instrumentation and rocker switches, plus LED-backlit gauges, switches and controls. A new multi-functional turn stalk integrates commonly used functions, such as flash-to-pass and wiper controls, into one location.

Wiring has been simplified by color-coding and numbering, and reliability has been improved through the addition of positive locking connectors at the critical connections, says Pete. 
The enhanced functionality of the information center provides drivers with access to critical vehicle performance data via the system display, so they can easily monitor the engine and transmission and adjust their driving to optimize fuel economy and performance. Fault codes have been replaced by easy-to-understand text-based readouts for faster and more accurate diagnostics, all controlled by a menu control switch for display navigation. Other features include an integrated clock with alarm, an automatic transmission display, and an optional controlled idle timer. The system is also equipped with the ability to change language — English, Spanish, & French.

The new electrical system is supported by Peterbilt’s Electronic Service Analyst (ESA), a computer-based diagnostic tool that monitors the electrical system, isolates sensors and gauges, and maintains an event log for historical purposes.
