Work
CAUTION
The Bentley ODIS-S Brand Version MUST be at least 2.35.2 (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 CABLECONNECTED 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 13.8v 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
Hybrid Vehicles use a High Voltage System and therefore MUST ONLY be worked on by suitable 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.
