Control Relay

WARNING: This page does not describe the selected car, but rather 11 other vehicles, including the 2001 Toyota Sienna, 2001 Toyota Sequoia, 2001 Toyota RAV4, 2001 Toyota Land Cruiser, and 2001 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: All models except Avalon, Camry Solara and Land Cruiser use a control relay to supply power to sun roof motor. Land Cruiser uses a sun roof ECU to control sun roof motor. To test ECU, see SUN ROOF ELECTRONIC CONTROL UNIT (ECU) .

Disconnect control relay connector. See COMPONENT LOCATIONS . Check for continuity or voltage as indicated at control relay wiring harness connector terminals with sun roof switch or limit switch in specified positions. See appropriate CONTROL RELAY TEST table. If test results are as specified, control relay circuits are okay. Replace control relay. If test results are not as specified, repair or replace appropriate switch or wire. See Fig 1 or Fig 2 .
