Initial issue
This Recall Campaign has been initiated because DCAG has determined that on affected vehicles the software for the engine control module may need to
be updated regarding fuel type for Flex Fuel Vehicles. Vehicles without the engine control module software update that are filled only with E85 fuel may
experience starting problems, rough vehicle operation and "Check Engine" lamp illumination. Extended operation of the vehicle with the "Check
Engine" lamp illuminated can result in possible catalyst damage. Dealers will update the engine control module software as required and check the
catalysts for damage and replace if necessary.
Prior to performing this Recall Campaign:
^ Please check VMI to insure the vehicle is involved in the Campaign and if it has been previously repaired.
Note:
Do not perform Recall Campaign P-RC-2007040005 in addition to or in place of this Recall Campaign.
^ Please review the entire Recall Campaign bulletin and follow the procedure steps exactly as described.
A sample copy of a letter which owners of the affected vehicles will receive is shown in this bulletin.
Approximately 6,373 vehicles are affected.
