WIRELESS DOOR LOCK CONTROL SYSTEM(w/o Entry and Start System) Only Wireless Control Function is Inoperative
| DTC Code | DTC Name |
|---|---|
| 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
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.
When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.*
It is necessary to perform initializationClick hereafter registrationClick hereof the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.*

CHECK TRANSMITTER BATTERY (VOLTAGE)
Inspect the battery capacity.
Remove the battery from the door control transmitter assembly that does not operate (Click here). Attach a lead wire (0.6 mm (0.0236 in.) in diameter or less including wire sheath) with tape or equivalent to the negative (-) terminal.
Note:Do not wrap the lead wire around a terminal, wedge it between the terminals, or solder it. A terminal may be deformed or damaged, and the battery will not be able to be installed correctly.
-
Carefully pull the lead wire out from the position shown in the illustration and install the previously removed transmitter battery.
Note:When replacing the transmitter battery, before starting work, remove static electricity that has built up in the body by touching, for example, the vehicle to prevent the door control transmitter assembly from being damaged.
-
Check the transmitter battery voltage.
Tip:Measure the transmitter battery voltage while pressing the lock or unlock switch on the door control transmitter assembly.

CHECK WAVE ENVIRONMENT
Bring the door control transmitter assembly near the door control receiver, and perform a wireless operation check.
Tip: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.
