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
Note
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.
It is necessary to perform initialization after registration of the transmitter IDs into the door control receiver if the door control receiver has been replaced.
for Initialization:
for Registration:
for 12 Pin Type:
When replacing the door control receiver, read the transmitter IDs (tire pressure warning system) stored in the old ECU using the GTS and write them down before removal.
for 12 Pin Type:
First, confirm that there are no malfunctions in the tire pressure warning system. Refer to the How to Proceed with Troubleshooting procedure.

CHECK WAVE ENVIRONMENT
Bring the door control transmitter assembly near the door control receiver, and perform a wireless operation check.
Tech Tips
When the door control transmitter assembly is brought near the door control receiver, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
If the inspection result is that the problem only occurs in certain locations or times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
