IG2 Relay: Celica

IG2 fuse supplies constant battery voltage to one side of IG2 relay. When ignition is turned on, voltage is supplied from ignition switch to other side of IG2 relay and IG2 relay is then energized. When IG2 relay is energized, IG2 relay provides battery voltage to fuel injectors and ignition coils. IG2 relay is located in fuse/relay box at driver's side front corner of engine compartment, just in front of strut tower, near battery.
