Install”.
C. Run the engine at high idle with no load for a minimum of 20
minutes.
Note: During the following step, there are two versions of the
“Aftertreatment Recovery Procedure” . One version is for engines
with a DPF. The other version is for engines without a DPF. En-
sure that the correct procedure is used.
D. Use the electronic service tool to perform the “Aftertreatment
Recovery Procedure” . While the procedure is progressing, check
for smoke from the exhaust. Some smoke will be evident during
the procedure. The smoke must dissipate before the procedure is
completed.
Note: Engine RPM Override may be necessary to complete the
Aftertreatment Recovery Procedure.
CEM Result: The “Aftertreatment Recovery Procedure” com-
plete successfully.
Proceed to Test Step 13.

Power Take-Off - Test
Note: This procedure only applies to engines
equipped with Power Take-Off (PTO) switches.
Use this procedure under the following
circumstances:
• The correct supply voltage to the PTO switches is
suspect.
• Operation of the PTO switches is suspect.
Note: Some applications may only have one PTO
switch.
The PTO switches provide the operator with the
ability to select the desired engine speed. Engine
speed will decrease with increasing load. The PTO
switches can be used to control the engine speed.
The engine has the following options of set speed
control:
• Single speed
• No speed (no PTO control)
