12V Battery Compatibility | Continental GT/GTC/Flying Spur | 26MY

Customer statement / workshop findings
This TPI is intended to give definitive guidance on the installation of the latest 12V battery in 26MY vehicles.
The need for clarity arises due to software dependencies that affect battery approval and functionality.

Technical background
The latest 12V batteries (refer to parts information) are approved for use only on vehicles operating with
baseline software version BIL 108.4. This baseline is implemented through software updated as instructed in
this TPI. Vehicles not updated to BIL 108.4 must not be fitted with these batteries, as it is not validated
outside of this configuration.

Production change
From baseline BIL 108.4 onward, the latest 12V battery is fitted in production vehicles without restriction. All
vehicles built with or updated to this baseline are approved for battery installation.

Measure
To install the latest 12V battery (Refer to Software Update Instructions) in a 26MY vehicle, also confirm the
actions below are complete.

Access and check the 12V battery part number currently fitted to the vehicle:
•

If a battery with Part No. 95C.915.105.J or 95C.915.105.JY is fitted, an SVM update (BIL update) must
be performed prior to installation (refer to SVM update instructions below).

•

If a battery with Part No. 95C.915.105.L or 95C.915.105.LY is already fitted and being replaced, no
SVM update is required, and the replacement can be carried out as a direct battery exchange.
NOTICE

Where an SVM update is required for vehicles fitted with Part No. 95C.915.105.J or 95C.915.105.JY,
verify whether service campaign ED59, ED65, or ED85 is applicable. If applicable and not yet completed,
the campaign must be carried out before proceeding with the subsequent instructions.

Software Update Instructions
CAUTION
The Bentley ODIS-S Brand Version MUST be at least 2.36.00 (or higher)

CAUTION
Before conducting the onward instructions, the operative MUST recheck the communication method in
ODIS and ensure that DoIP is selected before proceeding. Within ODIS-S, perform the following:
– On the right hand side, select the “Admin” tile (Within ‘Operating modes’)
– Select “GFF sequence” (Within ‘General information’ section)
– Under the “Selection of Communication path” drop-down menu, select “Only permit DoIP
communication”.

CAUTION
DO NOT, UNDER ANY CIRCUMSTANCES, ATTEMPT TO CONDUCT THE SOFTWARE UPDATE VIA
THE CAN NETWORK. ONLY DoIP SHOULD BE USED WHEN PERFORMING THE SVM UPDATE.

CAUTION
You MUST ONLY use the Diagnosis Interface VAS 6154 (WiFi Diagnostic Tool) in USB OPERATION or
the CABLE-CONNECTED VAS 5055 for the reprogramming (updating) of the control units.
– If neither of these units are available, the VAS 5054 (A) may be used in USB MODE.
– DO NOT under any circumstances use a Bluetooth connection to conduct the reprogramming
(updating) of any control units.

Battery Charger
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

Preparation before update
WARNING
Vehicles using a High voltage system MUST only be worked on by suitably qualified personnel

CAUTION
During the update, switch off all unnecessary consumers. For example, ventilation, seat heaters, interior
illumination, exterior lights ect.

Conduct a full guided fault find of the vehicle.
Address any unknown faults BEFORE conducting any of the below updates, referencing the applicable TPI.
Ensure that the correct battery charger is connected to the vehicle. – Refer to the ‘’Battery Charger’’ Section
above.

High Voltage Shutdown
WARNING
De-energise the high-voltage system via ODIS-S. Refer to ElsaPro, Repair Group 93 – “De-energising
high-voltage system” to do so.

SVM Code Input 1
CAUTION
At this point, a suitable battery charger must be connected to the vehicle.

1. After a suitable battery charger is connected, select the Special Functions tab.

2. Navigate to ‘SVM – Code Input’ and enter the applicable SVM Input 1 code if required from the SVM
applicability table.

NOTICE
Ensure that the Mirror server is connected when running the SVM code.

3. On the next screen, ensure that the SVM code is correct.

4. You will be shown the communication type. This MUST be set to “DoIP”.
a. If “DoIP” is not selected, select option 3 until the communication type is set to “DoIP”.

5. Ensure that the diagnostic device remains connected for the duration of the update.

6. Follow all on-screen prompts until the program ends.
a. You may be required to perform various ignition cycles during the test so ensure that you are situated
around the vehicle/ODIS-S device for the full update.

7. If you encounter any errors during the update, please refer to TPI 2078962 - ‘ODIS Error Message – Best
Practice When Performing Baseline (BiL) Updates’.
a. Please raise a FULL TECHNICAL DISS query.
b. Customer Statement: “2082051 Support”
c. Workshop Findings: Give a summary of the error encountered and ensure that the latest Guided FaultFinding log is submitted online.

8. Read the identification data from each ECU in the table below and verify that software versions match the
target.
