Integration Relay Operation (Avalon, Camry, Celica & Supra)

Turn ignition off. Remove integration relay from instrument panel junction block, below left side of instrument panel.
Using a jumper wire, connect positive battery terminal to integration relay terminals No. 1 and 7. See Fig 1. Connect a 12-volt, 3.4-watt test light between integration relay terminals No. 7 and 9. Using a jumper wire, connect negative battery terminal to integration relay terminal No. 10. Test light should be on and chime should sound for 4-8 seconds.
Repeat step 2 and operate chime again. With chime on, connect a jumper wire between negative battery terminal and integration relay terminal No. 8. Chime noise should stop. If operation is not as specified, replace integration relay.
