RVU 55F2 - Q5 tailgate flash
55 09 03
2021924/1
October 30, 2009
Affected Vehicles
Condition
This RVU has been proactively released to prevent the following condition from occurring in the vehicle:
^ The rear lift gate does not close automatically with a press of the button on the rear lift gate.
^ When this condition occurs, the following two DTCs can be set with time stamps that are five seconds apart. (For example, if DTC 03250 has a
time stamp of 12:36:10, then DTC 02364 should have a time stamp of 12:36:15.)
^ DTC 03250 (Luggage Compartment Closing Assistance Motor -V382- Open/Short circuit to Ground) in the comfort system central control
module (J393).
^ DTC 02364 (Closing assistance - Incorrect Signal) in the rear lid electronics (J605).
This Required Vehicle Update (RVU) is in effect until January 3, 2013. After that date, this RVU will expire and no longer be in effect.
Vehicle must meet all of the following criteria:
^ Procedure is valid only for vehicles that show the 55F2 code in the ElsaWeb Campaign/Action Information screen on the day of repair.
^ Vehicle must be within the Limited New Vehicle Warranty.
^ Procedure must be performed within the allotted time frame stated in this Technical Service Bulletin.
^ Procedure must be performed on applicable vehicles in dealer inventory prior to sale.
Technical Background
This sporadic condition is created when the comfort system central control module incorrectly detects insufficient current draw from the power
closing assist motor. As a result, the power closing assist motor is switched off while the rear lift gate automatically opens. The rear lid electronic
control module then disables the automatic closing of the rear lift gate. This also disables the closing button in the lift gate. From this point on, the
rear lift gate can be closed only manually, using a large amount of force. Once the lift gate is manually closed, the automatic opening of the lift gate
is restored.
Production Solution
Optimized software for the J393 comfort system central control module was put into series production.
Service
1. Check the software level (SW) of the comfort system central control module (J393) address word 46. If SW is 0324 or lower, proceed to step two.
If SW is 0326 or higher, no further action is necessary.
2. Follow all instructions in the attached TSB 2011732 00 Software Version Management (SVM), operating instructions.
