Trunk Opener Does Not Work With Remote Transmitter

WARNING: This page is about a different car, the 2000 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

  1. Checking Trunk Motor & Circuit

    Using fused jumper wires, connect battery voltage to trunk motor terminal No. 1 and connect trunk motor body to ground. See Figure. If motor operates, go to next step. If motor does not operate, replace trunk motor and retest system.
  2. Using DVOM, check continuity in White/Blue wire between trunk motor and body control ECU harness connector terminal B4-25. If continuity does not exist, repair open circuit in White/Blue wire. If continuity does exist, go to next step.

  3. Testing Body Control ECU

    Check all voltage inputs to body control ECU. See BODY CONTROL ECU  under PIN VOLTAGE TESTS. If any voltage inputs are not as specified, repair affected circuit and retest system. See WIRING DIAGRAMS . If all voltage inputs are as specified, substitute known-good body control ECU and retest system. If system now works properly, replace body control ECU. If system still does not work, recheck all related system wiring and connections.
