Work
Prior to performing the following campaign module 21 must be visible in diagnostics and be serviceable

If the vehicle is already exhibiting the failure mode, module 21 not visible in diagnostic log, then a hard reset of the vehicles electrical
system will be required ensuring module 21 is visible. To perform a hard reset of the vehicles electrical system disconnect and
reconnect the vehicle battery refer to workshop manual Rep.Gr.27.
After the hard reset, a short road test is required during which the vehicle road speed must exceed 30 MPH. Post this road test
check module 21, module D4 and module D5 for DTC’s. If no DTC’s are present in the three modules then it is OK to continue and
perform the software campaign.
If during the road test Bentley Dynamic ride warning illuminated and DTC B10CD00 displays in module 21 or D4 or D5 then the
Super capacitor must be replaced Rep.Gr.27. When this is the case the replacement Super capacitor will already contain the latest
software and therefore the vehicle will not require this software campaign.
