Action
Remove the bracket by sliding it off the re-
maining three attachment screws and put
it at a 90° angle from the base.
Putting the bracket at a 90° angle facilitates
the disconnecting of cables from the
bracket.
Note
Use caution when performing this procedure
order not to damage cables or other com-
ponents!
Disconnect cable clamps.
Unscrew the attachment screws securing
the SMB unit just enough to be able to re-
move the SMB unit.
Remove the SMB unit.
Disconnect the battery cable by pressing
down the upper lip of the R1.G connector
to release the lock while pulling the connect-
or upwards.
Disconnect the remaining connectors on
the SMB unit:
• R1.SMB1-2
• R1.SMB3-6
• R2.SMB
