Toyota CH-R Service Manual: Operation Check

OPERATION CHECK

NOTICE WHEN CHECKING THE FOLLOWING

(a) Wireless door lock/unlock function:

This wireless door lock control function operates only when the following 3 conditions are met:

(1) There is no key in the ignition key cylinder.

(2) All doors are closed.

(3) The power door lock system is operating properly.

HINT:

The unlock function operates even when a door is open.

(b) 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 door control transmitter 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 door control transmitter assembly uses weak radio waves, strong radio waves or electrical noise in the frequency used by the door control transmitter assembly may reduce the size of the operation area and the remote control may not function.

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

HINT:

If the door control transmitter assembly has been left in a place that is exposed to direct sunlight, such as on the instrument panel, it may cause the transmitter battery to be weakened or cause other related problems.
