After screw replacement and the condition of both sensors is confirmed as per specification, carry out Section 1 from point (I)
Should one or both of the proximity sensors not be as per specif"ication, carry out Sections 2 and 3
(I). Ensure a suitable battery charger - V/lS 5903 - or a charger with the same specifr:atbn is correctfl connected to the vehele electrea l system for
the duratbn of this procedure - Refer to workshop manual Rep.Gr 27 - Batteries to charge

- Connect the Bentley diagnoste tool V/lS 5052A or later approved equipment, to the vehele On Board Diagnoste (OBD) socket
