WARNING:
THIS MODIFICATION IS AUTHORIZED ONLY FOR THE LISTED ENGINE. PERFORMING THIS MODIFICATION ON OTHER ENGINE CALIBRATIONS IS UNAUTHORIZED AND COULD CREATE LIABILITY UNDER APPLICABLE FEDERAL OR LOCAL LAWS.
ISSUE:
The Malfunction Indicator Lamp (MIL) may illuminate with one of the following Diagnostic Trouble Code (DTC) groups P0300, P0301, and P0304, or P0302 and P0303 stored in memory with no driveability concerns present. This may be caused by the Powertrain Control Module (PCM) calibration.
ACTION:
Reprogram the PCM. The revised calibration should reduce the possibility of the MIL illuminating. Refer to the Recalibration Cross Reference Chart for the correct calibration.
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 Modification Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
