NOTICE
If the RED engine shutdown LED is ever ON (Figure 57),
John Deere recommends that the DPF be removed,
cleaned or replaced. In addition the shutdown code
must be cleared. To clear the code, the ECM must
be reset by a licensed John Deere Engine Service
Technician, using John Deere service software.
NOTICE
Soot and ash will accumulate in the DPF over time and
must be cleaned. The ash is a result of the normal oil
consumption while the engine is operated. The ash
cleaning interval will largely depend on the engine's
duty cycle and condition. Normal service intervals for
cleaning ash from the DPF is every 6 months (5000
hours).
