Digital Databuses – J1939 2007 Spartan Chassis have multiplexed gauges. The gauges use J1939 as the source for all of the engine and transmission information speedometer acts as master gauge: Speedometer Tachometer Oil Pressure Engine coolant temp Voltmeter Transmission temp The fuel and air pressure gauges are not read from the J1939 databus.

Auto Neutral Feature Transmission shifts to neutral when the PB is set Tachometer displays “Range Inhibit” Shifter displays left segment flashes the gear you had selected Right segment “N” The transmission is in neutral but does not send out a neutral signal Starter button doesn’t work Functions dependant on neutral signal don’t work Fast idle, PTO, Etc…

DPF Diesel Particulate Filter Also known as Aftertreatment device, Catalytic converter Critical component for emission compliance Collects particulate matter Must regenerate periodically Passive (no action required by operator) Active (manual switch must be activated)

DPF Switches DPF override Disables regen DPF Activates manual Regen

DPF Lamps DPF HEST MIL Diesel Particulate Filter Indicates Regeneration required HEST High Exhaust System Temperature MIL Malfunction Indicator Lamp (DDC Only)

DPF Lamp Indicates need to regenerate DPF Steady on indicates need to perform regeneration Least serve level Drive it hard - or Stationary with manual switch

DPF Lamp Indicates need to regenerate DPF Flashing indicates need to perform regeneration Moderately serve level Stationary with manual switch Failure to regen will lead to potential engine derate

DPF Lamp & Check Engine Lamp Indicates IMMEDIATE need to regenerate DPF High severity level Stationary with manual switch Failure to regen will lead to potential severe engine derate

Stop Engine Lamp Indicates DPF cannot be regenerated DPF is too restricted to be regenerated Must be serviced by authorized engine service center.

HEST Lamp Indicates high exhaust temperatures Temperatures vary with engine model May be speed interlocked Can come on during normal operation Will come on during regeneration

MIL Lamp Malfunction indicator lamp Indicates an emissions related fault Detroit Diesel engines only
