Transit Relay
The purpose of the Transit Relay is to prevent the
battery from being discharged during transit and
Dealer storage. It automatically isolates the
battery following ignition off.
The transit relay is installed on the Negative line
through a spur from the trunk lighting harness
and is located on the battery Negative post.
If the vehicle is to be handed over to a customer
within a period of 24 hours of completion of the
PDI, the Transit Relay MUST be removed.
If the vehicle is NOT to be handed over to a
customer within a period of 24 hours of
completion of the PDI, a Transit Relay Test Lead
must be fitted to allow the PDI to proceed.
Under no circumstances should any means other
than the test lead be used to bridge the Transit
Relay.
The Transit Relay Test Lead MUST be removed
after the completion of the PDI and stored for
further use. Under no circumstances should the
vehicle be transported with the Transit Relay Test
Lead fitted.
The procedure to fit the Transit Relay Test Lead
and remove the Transit Relay is given in the PDI
Manual.
