CALIBRATION
Refer to the Recalibration Cross Reference Chart in this TSB article for affected calibrations.
WARNING
THIS MODIFICATION IS AUTHORIZED ONLY FOR THE LISTED ENGINE(S). PERFORMING THIS MODIFICATION ON OTHER ENGINE CALIBRATIONS IS UNAUTHORIZED AND COULD CREATE LIABILITY UNDER APPLICABLE FEDERAL OR LOCAL LAWS.
ISSUE
The engine cooling fan may not shut off after ignition key is turned off, or battery may discharge as a result of engine cooling fan not turning off on some vehicles. This may be caused by the Powertrain Control Module (PCM) calibration.
ACTION
Reprogram the PCM and replace the cooling fan relay. The revised calibration should reduce the possibility of the cooling fan running after the vehicle is shut off. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
1. Verify concern by determining if engine cooling fan continues to operate after ignition key is shut off.
2. If battery is discharged, connect battery charger and check cooling fan operation.
3. If cooling fan continues to operate in either of these circumstances reprogram the PCM and replace the Cooling Fan Relay (F5RZ-14N089-CB). Refer to the following Recalibration Cross Reference Chart for correct calibration usage.
NOTE
PCM REPLACEMENT IS NOT AUTHORIZED BY THIS TSB. REFER TO THE POWERTRAIN CONTROL/EMISSIONS DIAGNOSIS (PC/ED) SERVICE MANUAL FOR APPROPRIATE DIAGNOSTIC PROCEDURES IF PCM HARDWARE CONCERNS EXIST.
Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed.
