"SITUATION: WHILE DRIVING IN WET WEATHER CONDITIONS, CONDENSATION MAY BUILD UP WITHIN THE ENGINE CHARGE AIR
COOLER. FOLLOWING A RAPID INCREASE IN ENGINE SPEED, THIS CONDENSATION COULD BE DRAWN IN TO ONE OF THE ENGINEÂ’S
CYLINDERS, CAUSING THE ENGINE MANAGEMENT SYSTEM TO SENSE A MISFIRE. THE ENGINE IS PROGRAMMED TO REACT TO THIS
MISFIRE BY INITIATING A RESTRICTED PERFORMANCE MODE TO PROTECT THE EXHAUST CATALYST. IN THIS MODE, THE DRIVER
NOTICEABLY EXPERIENCES REDUCED POWER TO ACCELERATE UNTIL THE ENGINE IS SWITCHED OFF AND THEN RESTARTED.
FURTHERMORE, AN ENGINE WARNING MESSAGE WILL DISPLAY IN THE INSTRUMENT CLUSTER MESSAGE CENTER AND THE ENGINE
MALFUNCTION INDICATOR LAMP MAY ILLUMINATE.
NEW COMPONENTS HAVE BEEN DESIGNED TO LIMIT CONDENSATION FROM BUILDING IN THE ENGINEÂ’S CHARGE AIR COOLER TO
PREVENT THE RESTRICTED PERFORMANCE MODE FROM INITIATING. ADDITIONALLY, UPDATED ENGINE CONTROL MODULE (ECM)
SOFTWARE HAS BEEN DEVELOPED WHICH CHANGES THE THRESHOLDS NECESSARY TO INITIATE THE RESTRICTED PERFORMANCE MODE
FOR THIS ISSUE."
