4.1 REQUIREMENTS

The interval of recommended maintenance related to ash removal from the Diesel Particulate Filter islisted in Table2.

NOTE:

The DDEC VI engine control system monitors and controls the Aftertreatment Device for collected

ash volume. In the event that maintenance is not performed or if maintenance is required due to

unforeseen issues, the Amber Warning Lamp (AWL)/Check Engine will be illuminated to notify the

user that service is needed. Refer to section 6.2.3.

5 REGENERATION STRATEGY

Regeneration of the Aftertreatment Device (ATD) is fundamental for the oxidation of soot. This proceshappens during the normal operation cycle of the vehicle; it can occur both passively and actively. Th

operator will see no difference in vehicle performance or vehicle control.

There are three types of regeneration that can occur:

Passive Regeneration

Active Regeneration

Parked Regeneration

The following describes the regeneration strategy for the Detroit Diesel Aftertreatment System. See

Figure1for Series 60, Figure2for Series 60 idle timing, Figure3 for MBE 4000, Figure4 for MBE

900, Figure5 for DD15, and Figure6 for DD15 idle timing.

5.3 PARKED REGENERATION

When the request is accepted, the DPF Regeneration Lamp will turn on for one second and then go offor the rest of the parked regeneration. The engine rpm will increase to the required level as listed i

Table3.

6.1 MECHANICAL TROUBLESHOOTING

Listed in Table 4 are the common symptoms and possible causes to guide you through mechanicaltroubleshooting if regeneration is not functioning properly when initiated via the dash switch.

Symptom Possible Causes Suggestions

Low fuel supply pressure Manual test fuel pressure. Check for plugged fuelfi lters

or aerated fuel.

Fuel Doser Valve partially plugged

Monitor Doser Injection Status and Doser Fuel Line

Pressure. A high Doser Injection Status during regen,

usually greater than 25% and doser fuel line pressure

close to engine fuel pressure indicate plugging.

Intake Manifold Pressure Sensor

inaccurate Compare reading to BARO (key ON, engine OFF).

DOC Outlet Temperature Sensor

non-responsive

Compare temperatures before and after engine startup.

No temperature change indicates sensor problem.

Electronic Dosing Valve

inoperative

Monitor fuel line pressure. Pressure should change when

valve commanded to open (PWM > 0).

Fuel Cutoff Valve inoperative Monitor fuel compensation pressure. Pressure should

change when valve commanded to 100%.

A parked regeneration initiates

and runs indefinitely. (Intake

throttle on Series 60, DD15, and

MBE 4000 or Exhaust Flap on

MBE 900 closes, and there is no

HEST Lamp after 25 minutes.)

DOC not active Monitor temperature rise across DOC during regen. Little

or no temperature rise indicates DOC not active.

Low coolant temperature Monitor coolant temperature. Temperature should be

greater than 60C (140F).

High DOC Outlet temperature Monitor DOC outlet temperature. Temperature should be

greater than 100C (212F) prior to regen.

A parked regeneration initiates

and runs indefinitely. (Intake

Throttle on Series 60, DD15, and

MBE 4000 or Exhaust Flap on

MBE 900 does NOT close, and

there is no HEST Lamp after 25

minutes.)Engine in smoke control mode

Monitor smoke control status during regen. Smoke control

status should be 0.

DOC Inlet Temperature Sensor

non-responsive

Monitor DOC inlet temperature. No temperature change

after engine startup indicates sensor problem.

Intake Throttle Valve not

functioning properly Listen for the ITV to sweep at key up.

Turbo not functioning properly Perform a turbo hysteresis test.

Low output of Engine Fuel Injector Check for plugged tip. Perform cylinder cut out test.

Exhaust Flap not functioning

properly (MBE 900) Check solenoid supply voltage and air pressure.

A parked regeneration initiates

but aborts. (Test ends after 10-15

minutes of activation of Intake

Throttle on Series 60, DD15, and

MBE 4000 or Exhaust Flap onMBE 900.)

Aerated fuel Check fuel for aeration.
