SUBJECT:
Flash: Power Sliding Door Module - Overly Sensitive Obstruction Detection
OVERVIEW:
This bulletin involves verifying there are no mechanical conditions that may lead to slow door operation, making mechanical corrections as necessary
and Flash Reprogramming both Power Sliding Door Module's (PSDM).
MODELS:
2008 - 2010
(RT)
Caravan/Town & Country
2008 - 2010
(RT)
Chrysler Grand Voyager (International Markets)
NOTE:
This bulletin applies to models with Power Sliding Doors (Sales Code JRA/JRB) built prior to November 16, 2009 (MDH1116XX).
NOTE:
If a power sliding door module is replaced for any reason, it is important to check the software level of the replaced module and flash update to the
latest software level. Verify part numbers prior to and after update to assure update has successfully completed.
SYMPTOM/CONDITION:
Some customers may experience the power sliding door intermittently not fully closing when activated with either the key fob or switches located in the
vehicle. The door will begin the closing process but then reverses at any point without any obvious obstruction or reason. The doors will close manually
with no apparent problem.
If the door slows below a threshold during the power close sequence, the system may misinterpret this as an obstruction and reverse the doors direction
to open. The detection threshold may be overly sensitive.
The new software will provide revised parameters for power sliding door obstruction detection but it is important to note the software cannot compensate
for mechanical problems that can cause the door to slow during a power close sequence.
DIAGNOSIS:
Using a Scan Tool (wiTECH(R)) with TechCONNECT and the appropriate Diagnostic Procedures, verify all door systems are functioning as designed.
If DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the Symptom/Condition or it can be reproduced, perform the Repair Procedure.
POWER SLIDING DOOR MECHANICAL CHECK:
NOTE:
The door must be aligned and move freely / smoothly manually before proceeding with the Flash Update.
