Service Plug
By removing the service plug before performing any inspection or service, the high-voltage circuit is shut
off at the intermediate position of the HV battery, thus ensuring safety during service.
The service plug assembly contains a reed switch for interlock. Lifting the clip lock up turns OFF the lead
switch, which shuts off the SMR. However, to ensure safety, make sure to turn OFF the ignition switch
before removing the service plug.
The main fuse for the high-voltage circuit is provided inside of the service plug assembly.
For further details on how to handle the service plug and other safety cautions, refer to the 2007 Camry
Hybrid Vehicle Repair Manual (Pub. No. RM02H0U).
