Remote Lube Filter Hoses Distributor support Remote Lube Filter Hoses 9/20/2018 Cummins Confidential

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.

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?

Off-Highway Diagnostic Improvement Project Scott Decker December 9th, 2014 Cummins Confidential

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

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

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

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

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 Cummins Confidential

Summary of the Fault Codes Covered by the Off-Highway DIG team Each recommendation was evaluated for how long to implement Reviewed all 700+ fault codes Cummins Confidential

Summary of Diagnostic Recommendations Cummins Confidential

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

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

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

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

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

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

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

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. Cummins Confidential

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

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 Cummins Confidential
