Has anyone experienced any sort of problems with the rear lift gate and both rear sliding doors where they just start opening and closing all on their own ?

Very intermittent problem. Rear hatch opening and closing all by itself, all keys on table, no one touching them, door opening and closing by itself. Same issue with the sliding doors.

Anyone experience this ?


Can anyone also tell me IF the key fobs can be reprogrammed or must you swap out for new remotes ?


thanks

THIS BULLETIN SUPERSEDES TECHNICAL SERVICE BULLETIN 08-011-08, DATED
MARCH 15, 2008, WHICH SHOULD BE REMOVED FROM YOUR FILES. THIS IS A
COMPLETE REVISION AND NO ASTERISKS HAVE BEEN USED.
THE wiTECH DIAGNOSTIC APPLICATION IS THE PREFERRED METHOD FOR
FLASHING ECUs.
HELP USING THE wiTECH DIAGNOSTIC APPLICATION FOR FLASHING AN ECU IS
AVAILABLE BY SELECTING “HELP” THEN “HELP CONTENTS” AT THE TOP OF
THE wiTECH DIAGNOSTIC APPLICATION WINDOW.
THE wiTECH SOFTWARE LEVEL MUST BE AT RELEASE 10.01 OR HIGHER TO
PERFORM THIS PROCEDURE.
StarMOBILE DESKTOP CLIENT or StarSCAN MAY ALSO BE USED TO PERFORM
THIS PROCEDURE.
StarMOBILE STANDALONE IS NOT SUPPORTED AND StarSCAN IS NOT
SUPPORTED FOR 2010 MODEL YEAR VEHICLES.
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).
NUMBER: 08-017-09
GROUP: Electrical
DATE: October 27, 2009
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®) 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.
1. Before performing the Flash Repair, mechanically check the door(s) to make sure they
move smoothly on their tracks. Manually open and close the doors feeling for any
binding or roughness. Make the following checks:
a. Strikers are in Line.
b. Lower hinge tensioner is in place and tight.
c. Center hinge roller is aligned and not binding.
d. No obstructions exist (examples - out of place weatherstrip, miss-routed or tight wire
harness or any other condition that could cause the door to slow or bind during the
power closing process).
e. Check door fit, flushness, and gaps. These can contribute to obstruction sensitivity.
2. Follow the procedures found in DealerCONNECT>TechCONNECT to make door
adjustments as required.
NOTE: Use standard labor operations for any mechanical adjustments required.

FLASH REPAIR PROCEDURE:
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the Power Sliding Door Modules (both sides) with the latest software. The
flash process will update the right and left modules. After reprogramming, the
following must be performed:
a. Clear any DTC's that may have been set in other modules due to reprogramming.
The wiTECH application will automatically present all DTCs after the flash and allow
the tech to clear them.
POLICY:
Reimbursable within the provisions of the warranty.

Thanks for the post.

But this is not the issue.

The issue is that the door or rear hatch had been closed and never opened for any reason.

They start off opening and closing all by themselves.

they updated the door software AGAIN thinking that it did not take initially.

Bottom line.... they still open and close by themselves even AFTER BEING CLOSED for hours.

No one is touching the remotes as they are sitting on a counter or on a table by themselves, nothing around them.



thanks for the post though.

 

The door modules must be a signal to open or close. Have the dealer call star center and see if they have any information.

 

I had this happen on our 2008 Grand Caravan when one of the key fob units had something stuck in the switch. If I rubbed my finger over the switch for that door, it would open and close and sometimes repeat a few times. I pulled the fob apart (thinking I would need a new one) and dislodged whatever was in there. It started operating correctly after that. So the fob or the wiring/switches for the automatic doors should be suspected as well. BTW the fobs have to be a long ways away to stop them from activating the doors.

Thank you for the information.
