WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Power main relay may also be referred to as power or PWR relay.
- Turn ignition off. Remove power main relay from driver side junction block. See Figure.
- Note identification of electrical terminals on power main relay. See Fig 1. Using ohmmeter, check that no continuity exists between terminals No. 3 and 5 on power main relay. Check that continuity exists between terminals No. 1 and 2 on power main relay.
- Using jumper wires, apply battery voltage and ground to terminals No. 1 and 2 on power main relay. Check that continuity now exists between terminals No. 3 and 5 on power main relay. See Fig 1. If continuity is not as specified, replace power main relay.
