CUMMINS Diesel Engine ISX Wiring Manual

Service Training EPA 2010 Update #1

2 Diagnostics Update  Nuisance fault codes fixed with the newest calibrations  Calibrations released on the INCAL CD – Engine ECM’s – Aftertreatment DEF controller • Calibrations are alphabetical so “Aftertreatment” is at the top of the calibration list • Same calibration for all DEF controllers at this time • Not yet available on QSOL  Numerous fault codes being revised and posted to QSOL  CM2250 wiring diagrams being revised to show additional

3 INSITE  Version 7.4 has a target release date of April 8, 2010 (at distributor locations)  Will include a DEF system pressure test feature – Allows pressure test of DEF plumbing – Aftertreatment DEF Dosing Valve does not need to be removed for this test – Some Fault Code troubleshooting procedures are being rewritten to reflect the availability of this test

4 PACCAR Cooling Procedure  SRT’s being updated, considering creation of a a PACCAR specific option

5 PACCAR Coolant Fill Procedure  Specific to PACCAR vehicles – No need to take notes as a decal is provided under the hood as a reference  Remove the surge tank fill cap (Do not remove the surge tank pressure cap)  Fill the system with premixed coolant through the surge tank fill neck  Start the engine and idle at low RPM for 2 minutes  Top off surge tank to the base of the filler neck while idling  Run engine at higher RPM and top-off surge tank to the base of the filler neck  Run engine at higher idle for 10 minutes  Reduce idle to low RPM and top-off surge tank to base of filler neck  Allow engine to cool and top-off surge tank to base of filler neck if necessary  Install the surge tank fill cap

6 Test Lead Usage Normal Pin to Socket relationship occurs when correct test lead is used Pin to Socket relationship following use of multimeter lead Pin to Socket relationship following use of incorrect test lead Integrity of connection is maintained Integrity of connection is lost Integrity of connection is lost

7 Wiring Harness Repair Options Spreadsheet  Great handout material (currently resolving release issues with QSOL)  Will eventually be on QSOL  Lists connector/sensor by engine – List of repair options such as a pig tail (of the correct wire gauge), terminal, etc. – List of required tools for that repair – Lists the correct test lead for each specific connector

8 New Test Lead Kit PDF  Already updated on QSOL  Early production test lead kits did not feature the test lead warnings and recommendations are in red

9 4919351 (Tyco - Sumitomo)  Used on combination sensors/actuators such as: – Intake manifold temperature/pressure sensor – Ambient air temperature/pressure sensor – ISB/C/L CM2150/CM2250 EGR control valve  This is NOT intended for use at the Aftertreatment DEF controller connector  If you force it, the test lead will fit inside the socket, but the socket will loose all tension  Repair of the Aftertreatment DEF controller connector is possible, but difficult – 4919564 repair pigtail in CM2250 wiring harness repair kits 4919351 Test lead DEF Controller Small Socket

10 Aftertreatment DEF Controller OEM Connectors  Two pin sizes on the connectors  Use the 3164596 “Framatome” male test lead for the large sockets  Use the 3164112 Amp/Bosch/Delphi Male test lead on the small sockets – Always hold this test lead when it is inserted into a socket or it may break off or damage the socket
