Adjust the Turbocharger Waste Gate Setting
Use the procedure below to adjust the turbocharger waste gate setting if applicable.
Illustration 7 g03743321
(1) Cap
(2) Locknut
(3) Adjustment screw
For engines with an adjustable exhaust bypass valve, adjust the valve to obtain a throttle angle of 60 degrees to 70 degrees at full load. The adjustment is made to obtain the correct angle of throttle at full load.
Remove cap (1).
Loosen locknut (2).
Turning adjustment screw (3) will increase the boost. Increasing the boost will decrease the throttle angle.Note: The bypass valve may require adjustment several times.
If the engine RPM is unstable, verify that the gas line pressures at no load and full load are within the correct range. The pressure must not vary more than 1.7 kPa (0.25 psi) for low-pressure systems.
Operate the engine throughout the expected load range. Verify that the engine RPM is stable. Verify that the following parameters are within the correct range at full load.
Throttle angle
Exhaust oxygen
CO
NOx
Check the final adjustments to the engine to ensure the compliance with the emissions requirement. Monitor the emissions analyzer. Verify that the exhaust emissions after the catalyst are within the limits. Refer to the engine TMI "Emissions Data" sheet.Malfunction Indication Lamp (MIL) Operation
Illustration 8 g03667543
(1) Malfunction Indication LampDrive Cycle : After an engine startup, if the event system does not find any fault condition of any of the MIL-related diagnostics for one minute after the Emission Feedback Mode turns to "Oxygen Feedback" that will be considered as one drive cycle. Every drive cycle needs an engine start. An engine stop is sufficient for the next drive cycle.For normal operation without a MIL diagnostic event in the previous drive cycle, the MIL will power on at every ECM power on. The MIL will stay on until the engine starts the cranking cycle.The engine ECM will turn on the MIL when there is an engine diagnostic code activated. The MIL will turn off when the diagnostic code is cleared. The MIL will clear either when the issue is corrected or has been attended to by a technician and been reset.The codes listed in Table 1 are emissions-related codes related to the MIL operation.Clearing the MIL : The MIL can be cleared using the EMCP panel by hitting the "Reset" button after the engine has been serviced. No factory password is required to clear the code.If the malfunction or system error does not recur for four drive cycles when the malfunctioning system is being evaluated, the MIL may shut off. For all other diagnostic codes, the MIL will turn off when the error does not repeat while the malfunctioning system is being evaluated.
