SUBJECT:
Flash: Launch Performance / Driveability Enhancements
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the GPEC Powertrain Control
Module (PCM) with new software.
CAUTION: VEHICLES EQUIPPED WITH A CVT TRANSMISSION MUST HAVE THE
TRANSMISSION CONTROL MODULE (TCM) CHECKED FOR THE LATEST
SOFTWARE LEVEL WHENEVER THE PCM SOFTWARE IS UPGRADED. IF
NEWER TCM SOFTWARE IS AVAILABLE, IT MUST BE INSTALLED.

NOTE: This bulletin applies to models equipped with a 1.8L, 2.0L or 2.4L gasoline
engine (Sales Code EBA, ECN or ED3) on PM/MK models built before April
21, 2007 (MDH 0421XX).
SYMPTOM/CONDITION:
Some customers may experience the following:
•
Automatic CVT models - Perceived lack of performance under light to moderate
acceleration from a stop.
•
All Models - Ticking Sound intermittently heard from the engine compartment.
Software changes have been made to improve the above bullet points. In addition,
changes to maximum RPM in neutral have been made to assist A/C compressor function
during cold ambient temperatures to prevent A/C compressor slugging.
