Revised Inducement Exit Strategy 4094J

Replaces previous versions of 4094A, B, C, D, E, F,G and H.

With the latest Mid 128 and 233 and PTT updates, the NOx evaluation (simply a service regen that recognizes the presents of the 4094 code) is done with the service tool now and not a road test. The service tool should direct you there when you have the derate faults and have proceeded far enough through the GD checks. If the Nox evaluation is successful both the causal and derate faults should become inactive and can then be cleared. The Nox evaluation will last longer than a normal regen (45 minutes to an hour plus) and may have to be performed twice. The tool should direct you through this.

SNM 11-09 or SNV 11-09 should be performed for EGR checks. Along with the checks in the service letter you should disconnect EGR piping and verify the valve is able to close when unplugged. Minor leakage is acceptable. During the regen the EGR Mass flow and Delta Pressure should be very low.

SNV 11-10 or SNM 11-10 should be followed also paying attention to the inactive or pending faults. Item 6 can be ignored as the road test is no longer required to do the evaluation.

Verify that the proper NOx sensors are in the proper positions. (Grey connector on the inlet – Black connector on the outlet)

FSB 258-026 NOx Sensor relocation should be performed if applicable.

Verify doser is aimed towards center of exhaust stream.

Remove inlet to DPF, with engine at normal temp, snap throttle. Any excessive smoke? Remove inlet to SCR, with engine at normal temp, snap throttle. Any excessive smoke? Light smoke upon accel at DPF inlet is normal, should be no smoke exiting DPF.Any signs of soot in piping or stacks? List all results in the eService case.

Note operating conditions when the fault sets.

Attach GDR to case using print to PDF or XPS format. Be sure items are expanded.

If you run the diag in GD with no fault found submit a concern report from the service tool, should be done whenever GD is incorrect or inconclusive.

If no issue is found active or inactive that could have caused the faults a road-test can be performed following info below using 1700-08-03-06 in Vcads. Unit should be under load as much as possible and at a steady state. Values while engine is in transition do not provide much value.

If the unit is a MRU or LEU the unit should be test drove the same way the customer uses the unit. This includes using the hydraulics (forks, side arms, stop and go).

Run the truck at high idle for 10 to 15 minutes before you perform the sensor values test drive, this will allow the exhaust heat time to heat up the NOx sensor. The NOx sensors do not report data until they have reached 482 degrees for 10 minutes. You can also start your test drive then start capturing data after the exhaust has heated the NOx sensors for 10 minutes.

Attach road-test to SR in HTML format.

Under "Advanced Setup" be sure "yes" is selected under "save to jobcard"

When all the PIDs and PPIDs are selected, select Save Template on the right of the screen and save this selection as anything you want to call it (ex. “Sensor Monitoring”). This creates a Template that can be reused any time it is needed. To retrieve the Template just created, just select Retrieve Template on the right of the screen, find it and Open it. Then continue as indicated below.

Now select the Graph button at the right of the screen, and select the start button when ready to record the data.

Finalize the Jobcard and attach it to the eService case.
