Description & Operation

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.

WARNING: Vehicle is equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see SERVICE PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in TOYOTA - AIR BAG RESTRAINT SYSTEMS article.

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

NOTE: Toyota service calls the keyless entry system a Wireless Door Lock Control System.

Keyless entry system allows all doors and luggage compartment to be locked and unlocked by the use of a remote hand-held transmitter. All keyless entry functions are controlled through the body control Electronic Control Unit (body control ECU). A wireless door lock control receiver communicates with remote transmitters and relays information to body control ECU. Wireless door lock control receiver is protected by a DOME (7.5-amp) fuse located in driver side junction block. See Figure. Driver and passenger door ECUs communicate with body control ECU over a multiplex communication network and control power door lock motor for that door. Power door locks for rear doors and luggage compartment are directly operated by the body control ECU.

Depressing remote transmitter UNLOCK button once will unlock driver door. Depressing remote transmitter UNLOCK button again within 3 seconds will unlock all doors. UNLOCK function will not work if key is left in ignition switch. A period of 30 seconds is given to open any door after LOCK function with remote transmitter has been performed. If no door is opened within the 30-second delay, all doors will automatically lock again. LOCK function will not operate if key is left in ignition switch or if any door is not securely closed.
