DISCUSSION:
The 6.7L Cummins(R) Turbo Diesel Common Diagnostic Process was developed for any drivability concern on the 6.7L Cummins� Diesel Engine. Non-drivability engine issues or engine cooling system issues are not in the scope of this process.
The process begins by identifying the customer's concern and applying it to one of the following symptoms:
^ MIL Illumination
^ Engine Cranks But Does Not Start or Starts and Immediately Stalls
^ Engine Surges, Bucks, Runs Rough - No MIL
^ Engine Noise - No MIL
^ Excessive Black Smoke Out Exhaust - No MIL
^ Excessive White Smoke Out Exhaust - No MIL
^ Excessive Blue Smoke Out Exhaust - No MIL
If the MIL is illuminated, for 2007 - 2009 DH/D1 and 2007 - 2010 DC/DM models, your process begins in TechCONNECT > Service Info > 28 - DTC Based Diagnostics > MODULE, Engine Control (ECM), 6.7L > Standard Procedure > PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE. 2010 - 2012 DJ/D2 models, your process begins in TechCONNECT > Service Info > 28 - DTC Based Diagnostics > MODULE, Powertrain Control (PCM), 6.7L > Standard Procedure > PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE. 2011 - 2012 DD/DP models, your process begins in TechCONNECT > Service Info > 28 - DTC Based Diagnostics > MODULE, Powertrain Control (PCM), DD/DP - Chassis Cab > Standard Procedure > PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE.
If the MIL is NOT illuminated, your process begins in TechCONNECT > Service Info > 29 - Non-DTC Diagnostics > Drivability - Diesel, 6.7L > Diagnosis and Testing>PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE.
In each case, the test procedure will request that a 6.7L Diesel Diagnostic Worksheet be completed before proceeding. Once the data has been collected and analyzed, then the diagnostic process can continue.
