Section 1 – Initial Glass Set Measurements
NOTICE
Conduct initial glass set measurements and record the results in the model specific measurement
document attached (see documents section). After completing the initial measurements, DO NOT make
any adjustments until after the software update has been completed
CAUTION
When completing the initial glass set measurements strictly adhere to the instructions in section 2
When completing measurements on Continental
GTC models, complete a set of measurements with both
the roof up and the roof down, as per the attached glass set measurement sheet
Section 2 – Glass Set Measurement Instructions
CAUTION
When completing the glass set measurement procedure, strictly adhere to the instructions below
If unsure about the measurement process follow the video on eAcademy or raise a full technical DISS query.
To eliminate confusion about the usage of WT10549/3 and the Y axis profile measurement between the front
and rear windows and how to correctly read/enter the measurements in the tables, please refer to the below
images to aid with accurate reading of the Y axis profile when using WT10549/3.
Window Parallel
When the window is parallel take the 2mm step from the tool and minus the 2mm gap between front window
and tool = -0mm (as shown in figure 1)
Figure 1
When the rear window is 0mm inboard from the front glass and the windows are parallel, the measurement
written as 0mm (figure 2)
Figure 2
Rear Window Inboard
When the rear window is inboard and there is a 2mm step from the tool, when there is no gap between either
window and tool (figure 3), the recorded measurement should be -2mm (figure 4)
Figure 3
Figure 4
Rear Window Too Far Inboard
When the rear window is inboard and there is a 2mm step from the tool as well as an additional 1.5mm gap
to the window (figure 5), the recorded measurement should be -3.5mm (figure 6).
Figure 5
Figure 6
If the tool (WT10549/3) does not sit flush against the rear window then this shows rear window is more than
2mm inboard (more than -2mm), check this by holding the tool on the front window and measuring gap
between the rear glass and the tool (as shown in figure 7)
Figure 7
eAcademy Videos
Further explanation can be found in the videos shown in Figure 8, which can be found on eAcademy Digital
Learning Hub.

Section 3 - Software update to the rear door control modules 00BB and 00BC - Short drop function
elimination
CAUTION
ONLY Chargers that meet the approved specification on the Mandatory Equipment List (available on the
Bentley
Hub) MUST be used.
– The charger must be set to a mode where a MINIMUM of 90a is supplied to the battery during the
process. Typically, this is known as ‘Power Supply Mode’ or ‘DIAG+ Mode’.
– A voltage of exactly 14.8v must be set and maintained throughout the process.
– Please refer to the manual to ensure that these requirements are met before beginning any SVM
update
The following software update eliminates the rear window short drop function
1) Preparation before update
•
Conduct a full guided fault find of the vehicle.
If a ‘Check installation list’ pop-up appears, select ‘close’ (Figure 9)
Figure 9
Referring to TPI 2075920, address any unknown faults BEFORE conducting any of the below updates.
2) Referring to Figure 10 - Within the Special functions tab - Select SVM - Code Input (Point A)
• Select Perform test (Point B)
Figure 10
3) Referring to Figure 11 - Enter the SVM code 372WDD02
Figure 11
4) The control modules will automatically be updated one by one, starting with 00BB (Driver rear) and then
00BC (passenger rear)
Upon successful completion you will get a failure message of 8113 SVM Error
NOTICE
If you get any other error code, such as 8118, please refer to TPI 2078962
5) On completion open the doors and ensure that the rear windows no longer drop.
6) Switch off the ignition
•
Remove the diagnostic interface from the OBD port
•
Switch off and remove the battery charger from the vehicle
•
Close the bonnet, boot and all doors
•
Lock the vehicle

Wait 5 minutes to allow the vehicle to go into bus silence
•
When 5 minutes has elapsed, unlock the vehicle and open the driver’s door
•
Switch on the ignition
7) Once the software update has been conducted continue with the remaining instructions
Hint: The remaining instructions MUST be conducted regardless if adjustments were conducted or not
8) Referring to Rep.Gr 64 - Measure and record the points as detailed below on the left and right hand side
Profile (Y-Axis) and Interlock (X-Axis).
CAUTION
Strictly adhere to the instructions in section 2 when completing the glass set measurements after the
software update has been completed.
Note: Should the measurements for the left and right hand side be within specification please go to step 11
and follow all remaining steps until completion
Or
NOTICE
Should one or both of the measurements not be within specification the operative must refer to Rep.Gr 64
- Rear door drop glass - To adjust and conduct the front and rear glass adjustment procedure for the
affected side left and / or right hand side to completion (all steps) and record a final measurement in the
attached document
CAUTION
All measurements must be recorded in the attached measurement documentation and saved as they will
be required to be attached to a non-technical DISS query at the end of the procedure
FAILURE TO ATTACH THE MEASUREMENTS TO THE DISS WILL RESULT IN NON PAYMENT OF THE
WARRANTY CLAIM
Note: Once the adjustment has been conducted please go to step 10 and follow all remaining steps until
completion
9) VERY IMPORTANT - Referring to Rep.Gr 64 - Side glass - To initialise
CAUTION
When conducting step 11 extra care must be taken to ensure the interior trim is suitably protected, any
water which enters the vehicle due to a leak must be dried / cleaned immediately. Ensure all windows,
sunroof and convertible roof (where applicable) are fully closed before conducting step 11
10) Conduct a water leak check to ensure that water is not leaking into the vehicles interior - Water leaks
must be resolved before handing over the vehicle to the customer
11) Conduct the PDI road test to check for any wind noise related issues
NOTICE
Should the vehicle fail the water leak check or a wind noise check, please raise a full technical DISS query
12) Upon successful completion of the PDI road test, raise a non-technical DISS query titled SC25/30 X and
Y Axis measurement feedback ensuring the following is attached
•
Online ODIS log
•
A completed model specific measurement table
13) Referring to the Identification section - Apply a blue paint completion mark on the engine partition brace
