Added SRT link, and fixed format issues 09/10/2015 - Changed verbiage in step 7 per feedback request. Added Warranty Note under Description 07/09/2015 - Updated link in Step 11 06/25/2015- Inserted break date for plant production update & control circuit update installation instruction 06/04/2015- Updated flexplate part numbers to match Automatic Transmission feature codes DESCRIPTION This document will guide the user through Cummins ISB starter and ring gear diagnostics. It is important to review all the material to prevent repeat failures, especially in instances of ring gear damage by the starter. NOTE: Warranty claims with a failure date of 09/21/2015 and later will not be allowed if the complete repair is not performed. See steps 10 and 11 of the diagnostics. As some vehicles may require an overlay harness to prevent repeat starter motor failures. SYMPTOMS Diagnostic Trouble Codes DTC/Light Description N/A Customer Observations or Concerns: Operator may hear one of the following from the starter: • • • • • • • • • Click Clunk Grind Squeal Starter spins, doesn't rotate engine Slow Engine Crank Click No-Crank No-Click No-Crank Crank No-Start SPECIAL TOOLS / SOFTWARE Tool Description Cummins Insite Tool Number Comments Cummins Tool Midtronics ESP https://evalue.internationaldelivers.com/service_kb/DocTool/ArticleViewer.aspx?ControlI... 11/3/2015 IK0800503 ISB Starting System Diagnostics Page 2 of 6 Tools Resource Center PARTS Description MOTOR,STARTING 12V , 38MT DELCO Flexplate Flexplate Part Number Quantity Source From Application 8201039 1 Navistar Engine- ISB 3968672 29545469 1 1 Cummins Allison Trans- 0013ASP Allison 2000 Trans- 0013AVE Allison 3000 DIAGNOSTICS NOTE: Before performing any voltage drop test; inspect each cable end nut torque, insulation, routing, clipping, discoloration, and terminal arching Step Action Diagnostic Trouble Code Check: 1 Decision Yes. Go to appropriate diagnostic manual to diagnose crank no start symptom Review current health report for Cummins or Body Controller fault codes that may cause an extended crank condition (Crankshaft Position Sensor, Camshaft Sensor, Fuel System, Electrical codes) No. Step 2 Are there pending/active/previously active DTC's causing a crank no start? Step Action Manual Engine Barring Test: Decision Yes. (with no audible clunk noise) Go To Step 3 Have an assistant bar the engine over from the alternator pulley 2 TIP: If an audible noise is heard from the starter area when the engine is rotated by hand, there is most likely flexplate ring gear damage. Does the engine rotate freely, and no clunk noise was heard? Step Action Cranking RPM Test: 3 Yes. (With audible clunk noise) Go to Step 4 No. Diagnose engine lock up condition. Decision Yes. Go to appropriate Cummins crank no start diagnostic. Do NOT replace starter motor Monitor Engine RPM using Cummins Insite while cranking the engine No. Step 4 Does the engine crank? Step Action Perform battery test: 4 Decision Yes. Replace ONLY failed battery and then recheck for symptom Follow IK0800482- Battery Testing, Diagnostics & Maintenance No. Step 5 Is a warranty approval code (WAC) or failed battery result from any battery generated? Step Action 5 Starter Cable Voltage Drop Test: Decision Yes. Make required repair https://evalue.internationaldelivers.com/service_kb/DocTool/ArticleViewer.aspx?ControlI... 11/3/2015 IK0800503 ISB Starting System Diagnostics Page 3 of 6 No. Step 6 Follow Midtronics starter cable voltage drop test Is combined + & - voltage drop greater than 0.5v? Step Action 6 Decision Alternator Cable Voltage Drop Test: Yes. Make required repair Follow Midtronics alternator cable voltage drop test No. Step 7 Is combined + & voltage drop greater than 0.5v? Figure 1: Starter IMS S terminal DVOM Hookup Location Step Action Starter Control Circuit Check: Decision Yes. Perform starter control diagnostics for possible causes: Wiring Connect DVOM test leads on IMS (Mag switch) "S terminal" and ground to solenoid F3A Fuse Start Relay (Neutral Relay) case as indicated in Figure 1 Crank Inhibit Relay 7 Have an assistant hold keyswitch in start position for 5 seconds. Compare DVOM IMS (Mag switch) "S terminal" reading to B+ voltage at batteries Clutch Switch (Manual Trans) TCM (Auto Trans) ECM Key Switch No. Step 8 Does the DVOM not read battery voltage +/-0.5 volts? https://evalue.internationaldelivers.com/service_kb/DocTool/ArticleViewer.aspx?ControlI... 11/3/2015 IK0800503 ISB Starting System Diagnostics Page 4 of 6 Figure 3: Flexplate/Flywheel Ring Gear Step Action Flexplate/Flywheel Ring Gear Inspection: Decision Yes. Step 9 Remove starter Mark the flexplate ring gear with a paint pen 8 Have an assistant bar the engine over while you inspect each tooth for damage: burrs, milling, chips, etc. (Figure 3) No. Inspect each tooth TIP: This can be done as a one man operation using a borescope or by looking through the starter mount hole Did all 127 teeth get inspected? Step Action Flexplate replacement determination: 9 Decision Yes. Replace flexplate & starter and then go to step 10 No. Replace starter and then go to step 10 Does the flexplate need to be replaced when ring gear teeth are compared to Figure 3? Step Action Build date inspection: Decision Yes. Step 11 No. Repair complete 10 Inspect truck or bus build date Was the truck or bus build on or BEFORE 5/31/2015? https://evalue.internationaldelivers.com/service_kb/DocTool/ArticleViewer.aspx?ControlI... 11/3/2015 IK0800503 ISB Starting System Diagnostics Page 5 of 6 Figure 4: Rectifier Diode Inspection Step Action Decision Overlay harness inspection: 11 Yes. Repair complete (state in warranty claim the harness was installed prior to repair) Inspect for previously installed rectifier diode assembly -CE Bus located on trunk of harness under dash next to cowl on driver side Durastar located near relay block No. Follow instructions Click Here Is the overlay harness with rectifier diode installed when compared to Figure 4?
