Symptom/Condition:
Some customers that flood the engine during starting may try to perform a clear flood (WOT) procedure to help start their vehicle.  Currently this feature is not operational on the above, and if used may worsen the flooded condition.

Diagnosis:
Using the Mopar Diagnostic System (MDS/MDS2)  or the Diagnostic Scan Tool (DRB III), verify that all engine/transmission systems are functioning as designed. If other DTC's are present, repair as necessary before proceeding with this bulletin. If no DTC's are present and the vehicle was brought in for a flooded condition, perform the repair procedure.

NOTE:  Whenever a PCM is replaced due to failure, the software of the replacement controller should be verified for the latest revision level. Use the flash procedure to updated replaced controllers as necessary.

Repair: PCM must be reflashed.

NOTE: The Mopar Diagnostic System is required to perform the ECM flash. The system must be operating with release 21 or higher AND TIL CD RELEASE 1175 or higher must be installed.
