ACTION
If one of the listed conditions occurs, the instrument cluster needs to be replaced. Additionally, on some 2002 7.3L applications the powertrain
calibration must also be reprogrammed in order to maintain compatibility between the instrument cluster and powertrain calibration. Refer to the
following Service Procedure for details.
SERVICE PROCEDURE
NOTE
SOME EARLIER LEVEL INSTRUMENT CLUSTERS WHEN USED IN CONJUNCTION WITH LATER LEVEL 7.3L POWERTRAIN
CALIBRATIONS MAY RESULT IN A FALSE P0600 DIAGNOSTIC TROUBLE CODE (DTC) ON F250/F350 WITH CALIFORNIA
POWERTRAIN CALIBRATIONS AND ALL EXCURSIONS, DUE TO UNRELATED ADDITIONAL REVISIONS CONTAINED WITHIN THE
POWERTRAIN CALIBRATION.
