Toyota Sienna Service Manual: Inspection
1. INSPECT GARAGE DOOR OPENER
- Press the switch and check that each red LED turns on. If one or more of the switches does not turn on the LED, confirm normal operation of the fuse and wire harness, then replace the garage door opener.
2. INSPECT GARAGE DOOR OPENER REGISTRATION AND TRANSMITTING
HINT: Use the home link tester made by KENTMORE for this test. Because it is necessary to register the code of the hand-held transmitter, the customer's code should be erased. When the inspection is complete, register the customer's code again.
- Check that the code of hand-held transmitter for inspection can be registered.
HINT: If the code cannot be registered, replace the garage door opener.
- Press the switch which inspection code has been
registered for and check that LED (green) of the
home link tester lights up.
HINT: If the LED (green) does not light up, replace the garage door opener.
- When the inspection is complete, reregister the customer's transmitter code(s) again.
