(signal strength) to the Emergency Assistance network, the warning will clear when the network signal strength improves.
Note: Irrespective of the warning message displayed on the DIP, the roof console SOS switch always displays the current status of
the Emergency Assistance network i.e. Green lamp displayed confirms the system is available, Red lamp displayed, the system is
temporarily unavailable.

is no requirement to continue with the this Technical Product Information document. Use the information contained within

With Diagnostic Trouble Code (DTC) U153E00 stored in Address 75 and warning “ Auto SOS: fault. Function unavailable. Contact

•

Confirm “ Auto SOS: fault. Function unavailable. Contact your Bentley dealer” warning is currently, or was previously displayed

on the DIP, in addition note the colour of the Emergency Assistance (SOS) switch in the roof console (Red or Green).

•

If the DIP warning is present and the Emergency Assistance (SOS) switch is illuminated Green, the system is active and a connection is
being made to the Emergency Assistance system.

•

Carry out an ignition cycle (off/on), the DIP warning will then clear. If required, clear the stored DTC (U153E00) using ODIS.

•

If the DIP warning is present and the SOS switch is illuminated Red, check and record the following Measured Values - Address 75 –

Customer information
The Customer should be advised that the warning may appear on the Driver Instrument Panel if the vehicle is in an area with poor network signal
strength, the warning should clear following an ignition cycle if a network connection is available.
Inform the Customer that the colour of the Emergency Assistance (SOS) switch in the roof console confirms the connection status of the system.
If the switch is illuminated Green, the system is active. If the switch is illuminated Red, the system is not active due to the vehicle being in an area
with poor network signal strength. When the network signal strength improves, the switch will automatically display Green and Emergency
Assistance will be available.
