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.
  1. Turn ignition off. Remove Daytime Running Light (DRL) relay No. 2, 3 or 4. All DRL relays are in engine compartment relay block No. 2 located in front of coolant reservoir and beside windshield washer fluid tank at right front corner of engine compartment. See Fig 1.
  2. DRL relays No. 2 and 4 have the same configuration and are tested the same. See Fig 2. Using ohmmeter, check that no continuity exists between terminals No. 1 and 2 of DRL relay. Check that continuity exists between terminals No. 3 and 4 of DRL relay. Using jumper wires, apply battery voltage and ground to terminals No. 3 and 4 of DRL relay. Check that continuity now exists between terminals No. 1 and 2 on DRL relay. Replace DRL relay if continuity is not as specified.
  3. Test DRL relay No. 3 by using ohmmeter to ensure continuity exists between terminals No. 1 and 2, and No. 3 and 4 of DRL relay No. 3. Check that no continuity exists between terminals No. 3 and 5 of DRL relay. Using jumper wires, apply battery voltage and ground to terminals No. 1 and 2 of DRL relay. Check that no continuity now exists between terminals No. 3 and 4, and that continuity now exists between terminals No. 3 and 5. on DRL No. 3 relay. See Fig 2. Replace DRL relay if continuity is not as specified.
