Table 3-16. Deutz Engine Fault Codes
Description
The total time in standstill-regeneration
mode exceeds the long-limit threshold
within last 500h total engine run time. The
error is activated if the engine runs to many
times in Standstill regeneration.
SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
Stand-still mode is very often aborted by the
operator.
Stand-still mode does not reach required
temperature level and regeneration level is
therefore reached after a short time again
Action
Read out stand-still statistics => see service
manual:
Stand-still operation finished or often
interrupted by driver / engine shut-off? =>
Run stand-still and instruct operator
Stand-still operation required often by soot
load => Check dp DPF pressure sensor
Stand-still mode does not reach required
temperature level:
Check engine air path: Intake Throttle, EGR-
Valve
and turbocharger okay?
Any leakage in engine air intake system or
exhaust gas system?
Check temperature sensors within exhaust
system: upstream DOC, downstream DOC
If soot load level of DPf allow it:
Perform Stand-still and check reached
temperature level upstream and downstream
DOC: T upstream DOC in the range of 480-
550°C? Downstream DOC after 25 min stand-
still main phase 590°C are reached?
Temperature traces are steady and even?
Temperature downstream DOC higher than
upstream DOC but difference does not exceed
100 K?
Very small difference (< 10 K after 25 min
stand-still main phase, 590 °C downstream
DOC are not reached) => exchange DOC
Very big difference (>100 K after 25 min
stand- still main phase, 590 °C downstream
DOC exceeded) => check injection system of
engine & engine air path
