Vehicle Issue: Engine Dies While Driving. Code p2509 Sets.;Engine dies out while driving. Mil is on and code P2509 has set. Fuel transfer pump volume is low. For test procedures refer to the 2003 Powertrain Diagnostic Manual Page 260.
System or Component: Long Crank During Restart,Restarts Immediately - Runs Fine;Customer Concern (No DTCs),DTC / Error Message;Wiring,Battery,Charging System,Malfunction Indicator Light / MIL / Check Engine Light,Fuel Pump / Transfer Pump;Target Idle to 1500,1500 to 2000,2000 to 3000;Light Throttle,Moderate Throttle;Acceleration;Yes - Intermittent,Yes - Continuously;Fuel Pressure Low,Fuel Volume Low
Recommendation: Perform diagnostics for code p2509. Load test the batteries and charging system. Clean tighten the ECM, fuel transfer pump ground stud on the engine block located near the fuel filter.

Vehicle Issue: Engine Stalls Out. 'NO BUS' Message Is Displayed. P1652.;Power and ground connections to the Cummins ECM are good. P1652 and P2509 are set.
System or Component: Die out / Stall;DTC / Error Message;Electronic Control Module,ECM;Yes - Intermittent,Yes - Continuously
Recommendation: Inspect the wiring harness near the C108 (14 pin) connector. This connector should be at the back of the engine, near the transmission bell housing.

Vehicle Issue: MIL. P2509. The engine may stumble or stall out.;12 volt power (unswitched) and the ground circuits to the ECM are good. Batteries and charging system operation are good. If applicable (2006 and 2007 MY trucks), the ECM has already been updated per TSB 18-001-07.
System or Component: Die out / Stall,Hesitation / Sag / Stumble;DTC / Error Message;ECM
Recommendation: If the problem can be duplicated, disconnect the fan clutch 6-way connector and check if the concern still occurs. If the problem no longer occurs, replace the fan clutch assembly.
