This bulletin provides information related to charging system changes in 2003MY Sedona models to improve alternator output during high ambient
temperature severe operating conditions.
Some 2002 and 2003MY Sedona models built before 2/28/03 production may experience battery discharge when operated in high ambient temperatures
for extended periods of time at low speeds or at idle with A/C, headlamps and other accessories on. Typically this results in customers reporting an
inability to restart vehicle. To reduce incidence of battery discharge complaints, the following changes were made from 2/28/03 production:
^
Battery heat cover added
^
New alternator with smaller pulley (65 mm -> 55 mm)
^
ECM battery compensation revised.
For 2002 and 2003MY Sedona complaint vehicles produced before 2/28/03, the revised parts and logic software have been made available for use as a
field fix.
Refer to the field fix procedures outlined in this bulletin.
