DOOR LOCK  WIRELESS DOOR LOCK CONTROL SYSTEM(w/o Smart Entry and Start System)  Only Wireless Control Function is Inoperative  


DESCRIPTION

The door control receiver receives signals from the door control transmitter assembly and sends these signals to the main body ECU (multiplex network body ECU). The main body ECU (multiplex network body ECU) then controls all doors by sending lock/unlock signals to each door, and sends hazard flasher signals to the combination meter assembly.

CAUTION / NOTICE / HINT

NOTICE:
·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

When replacing or inspecting the door control receiver and wire harness, do not change the position or length of the wire harness. If the wire harness is too close to the door control receiver, wireless function performance may be affected.

·

Before replacing the door control transmitter assembly, refer to Service Bulletin.

·

If the door control receiver has been replaced, it is necessary to perform initialization (Click hereSuspension>TIRE PRESSURE MONITORING>TIRE PRESSURE WARNING SYSTEM>INITIALIZATION) after registration (Click here Suspension>TIRE PRESSURE MONITORING>TIRE PRESSURE WARNING SYSTEM>REGISTRATION ) of the transmitter IDs to the door control receiver assembly.
