Toyota Yaris: Wireless Door Lock Control System / Precaution

PRECAUTION

PRECAUTIONS WHEN USING GTS

(a) When using the GTS with the ignition switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

(b) After all DTCs are cleared, check if the malfunction occurs again 6 seconds after the ignition switch is turned ON.

PRECAUTION WHEN REPLACING PARTS

(a) If replacing any of the following parts, refer to the Registration.

(1) Certification ECU (smart key ECU assembly)

(2) Main body ECU (multiplex network body ECU)

(3) Electrical key transmitter sub-assembly

PRECAUTIONS FOR ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY

(a) The electrical key transmitter sub-assembly is a precision instrument. Be sure to observe the following:

(1) Do not subject the electrical key transmitter sub-assembly to strong physical shocks.

(2) Do not keep the electrical key transmitter sub-assembly in a high temperature area for a long time.

(3) Do not use an ultrasonic washing machine to clean the electrical key transmitter sub-assembly.

(4) Do not use the electrical key transmitter sub-assembly near any magnets or magnetized items.

(5) Do not place the electrical key transmitter sub-assembly near magnetic equipment, such as digital audio players, induction cookers, medical devices that generate low-frequency electromagnetic waves, etc.

(6) Do not attach any stickers to the electrical key transmitter sub-assembly.

(7) Do not disassemble the electrical key transmitter sub-assemblies.

(8) The mechanical key should only be used in an emergency, such as when the transmitter battery is depleted.

NOTICE FOR CHECKING WIRELESS DOOR LOCK CONTROL SYSTEM

(a) The size of the wireless door lock control operation area differs depending on the situation.

(1) The size of the operation area differs depending on the user and the way the electrical key transmitter sub-assembly is held.

(2) In certain areas, the wireless door lock control function will only operate partially for the operation area, which will be reduced due to the vehicle body shape and the influence of the surrounding environment.

(3) Since the electrical key transmitter sub-assembly uses weak radio waves, strong radio waves or electrical noise in the frequency used by the electrical key transmitter sub-assembly may reduce the size of the operation area and the wireless door lock control may not function.

(4) When the transmitter battery is weak, the size of the operation area is reduced and the wireless door lock control may not function.

(b) Multi channel function

The wireless door lock control system has a multi channel function. Each time the switch on the electrical key transmitter sub-assembly is pressed, the channel is switched alternately between 2 different frequencies and the signal is sent to the smart door control receiver assembly.
