WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT FUSE (ECU-IG, AM1) 
    1. Remove the ECU-IG and AM1 fuses from the instrument panel J/B.
    2. Measure the resistance of the switch.

      Standard: Below 1 Ω 

    1. NG : REPLACE FUSE 
    2. OK : Go to Next Step. 
  2. INSPECT RELAY (IG1) 
    1. Remove the IG1 relay from the instrument panel J/B.
    2. Check the resistance of the relay.
