11. QSB4.5 & QSB6.7 T3/T4F Remote Lube Filter - Hoses
The Problem
The factory believes some OEM are selecting Remote Lube filter hoses (options) and then discarding and replacing them with customer supplied ones?
The Solution
To release a new option Remote Lube filter option with no hoses allowing the customer to provide their own.
The challenge
To Justify a new option we need to show VOLUME.

12. QSB4.5 & QSB6.7 T3/T4F Remote Lube Filter - Hoses
The support we need
What OEM’s are replacing the supplied hoses that come with remote lube filter option LF9135, with their own hoses? Customer Code?
What is the volume of engines for those OEM’s?

13. Off-Highway Diagnostic Improvement Project

14. Agenda Background of the Diagnostic Improvement Project
Major Classifications for Changes
OEM / Customer Impact Overview
Improvement Schedule
Cummins Confidential

15. Diagnostic Improvement Group (DIG team)
Group of “experts” assembled to review all the fault codes across the off-highway HMLD product line (QSF2.8 through QSX15) and determine if we are taking the appropriate level of lamp activity, torque/speed derate, and proper tuning level based on the various architectures used across the off-highway product line.
Cummins Confidential

16. Motivation: Why do this?
Cummins losing HD truck share in North America
5% market share loss in last 2 months  $50M PBIT
Customer Feedback
ISX15 has too many lamps & derates in comparison to competition  Drives downtime
Our product is borderline intolerable  Need major improvement (>70%)
Some Customers are getting out of 2010 ISX15 powered equipment (USX) earlier than normal trade cycle
Customers consider Cummins “Lamp Happy”
“Know ISX15 is running – Yellow Lamp is on”
Evidence this is happening in all markets
Cummins Confidential

17. VOC – VPI -- Lamps & Derates Customer Pain Analysis
Lamp data
turned on
Lamp every 2 days for every vehicle
Lamp every 1-2 days for every vehicle
Lamp every 3-4 days for every vehicle
Lamp every day for every vehicle

18. Diagnostic Improvement Group (DIG) Team Deliverables
Objective:
Re-design diagnostics to provide meaningful operator communication of needed repair action
Maximize customer uptime
Drive appropriate customer response
Ensures correct repair action
Meets legislative requirements
Project Scope:
In Scope: Lamp strategy, accommodations / derates, diagnostic & tuning, interpretation of regulations
Out of Scope: Hardware degradation leading to faults or natural derates and Hardware improvements  Hopper of ideas

19. Summary of the Fault Codes Covered by the Off-Highway DIG team

700+ fault codes

20. Summary of Diagnostic Recommendations

21. Major Classifications of Changes
Lamp Changes
Accommodation Changes
Tuning Changes
DEF Lamp Changes
Cummins Confidential

22. Lamp Changes - Definitions
Red – Need to stop work immediately
Yellow – Run to the end of the shift
Maintenance – Operator can perform some action without special tools to fix the issue
No Lamp – Fault is used for problem identification and fault isolation by the technician
Cummins Confidential

23. Lamp Definition Strategy
Amber Warning Lamp: Equipment can be used to the end of shift. Arrange service.
Red Warning Lamp: Stop equipment now
Flashing AWL: Operator able maintenance Operator can perform some action without
special tools to fix the issue
Flashing
DEF Lamp Solid: DEF tank level is low or DEF quality is low or DEF/SCR system related malfunction occurred.
Leads to 25%, 50% torque derates
Flashing DEF lamp: Final Inducement after 30 minutes lock to idle or shutdown for Off-Highway)
Cummins Confidential

24. Lamp Changes
Possible OEM Impact
Change the definition of what lamp to turn on when the ECM detects an issue.
Amber Warning Lamp (AWL) to No Lamp
Amber Warning Lamp (AWL) to Maintenance Lamp
Red Lamp to Amber Warning Lamp
These changes will cause a new fault code number to be used (but maybe the same SPN/FMI)
Lamp, J1939 SPN/FMI make up a unique CMI fault code
Cummins Confidential

25. Lamp Changes
When a fault is moved to a no lamp condition, the fault’s SPN/FMI no longer shows up in the DM1 message on J1939.
The fault is still recorded in the ECM and is available upon request via the DM53 message on J1939
So the fault code is still available for servicing events but does not interrupt the operator. It is still available on the J1939 datalink but under a different message (DM53).
Cummins Confidential

26. Accommodation Change
Unlikely OEM Impact
Definition: Accommodation means the ECM turns off the EGR or SCR or both. Turning off EGR or SCR means the engine will go to a 25% derate.
Cummins Confidential

27. Accommodation Change
Unlikely OEM Impact
Minimizing the number of diagnostics that force the system into an accommodation is a reduction in customer pain because the customer is not put into derate as often.
Insert Data Classification

28. Tampering Improvement
OEM Impact
Moving a Fault Diagnostic out of the tampering list means the engine does not get locked on idle or shutdown.
In the future, diagnostics will be re-written to improve the distinction between actual potential tampering and unintentional failures.

31. Disable Diagnostic 29 Diagnostics were recommended to be turned off.
No OEM Impact
29 Diagnostics were recommended to be turned off.
These were most often diagnostics required for OBD products that we inherited from the on-highway programs but are not required for off-highway.
Less faults… less possibility of false indications which lead to stopped work.
Cummins Confidential

32. Tuning Changes
No OEM Impact
This would include actions to make sure the fault is real before indicating we have an issue.
We may take more time to determine that a system or component is truly in error.
Less false faults
