Toyota RAV4 (XA40) 2013-2018 Service Manual: Door control transmitter module
Components
Removal
- Remove transmitter housing cover
Notice:
Take extra care when handling these precision
electronic components.
- Twist the screwdriver in the direction of the arrow
mark in the illustration, and open the transmitter
housing cover.
Notice:
Do not forcibly pry the cover.
Hint:
Tape the screwdriver tip before use.
- Remove door control transmitter module
Inspection
- Inspect door control transmitter module
- Inspect operation of the transmitter.
- emove the battery (lithium battery: cr2016)
from the transmitter.
- Install a new or non-depleted battery (lithium
battery: cr2016).
Hint:
When a new or non-depleted battery is not
available, first connect 2 new 1.5 V batteries in
series. Then connect leads to the batteries and
use the leads to apply 3 v to the transmitter, as
shown in the illustration
- From outside the vehicle, approximately 1 m
(3.28 Ft.) From the driver side outside door
handle, test the transmitter by pointing its key
plate at the vehicle and pressing a transmitter
switch.
Ok:
door lock can be operated via the
transmitter. Led illuminates more than Once.
Hint:
- The operating range differs depending on
the user, the way the transmitter is held and
the location.
- The transmitter's faint electric waves may be
affected if the area has strong electric waves
or noise. The transmitter's operating range
may be shortened or the transmitter may not
function.
- Inspect the battery capacity.
Hint:
- When checking the amount of energy left in the
battery, the battery must be checked while it is
installed in the transmitter (a resistance of 1.2 Kù
is applied to the battery). When the battery
energy is checked by itself (uninstalled), the
voltage reading will be more than 2.5 V until the
energy is depleted.
- If the transmitter is malfunctioning, the voltage
reading of the energy left in the battery will be
inaccurate.
- Remove the battery from the transmitter.
- Connect a wire to the negative (-) terminal of
the transmitter and install the battery.
- Connect the tester's positive (+) lead to the
battery and the negative (-) lead to the wire.
- Press one of the transmission switches on the
transmitter for approximately 1 second.
- Press the transmission switch on the
transmitter again to check the voltage.
Standard voltage:
2.2 V or higher
Hint:
- When the temperature of the battery is low,
the inspection result will not be accurate.
When the inspection result is less than 2.2
V, conduct the test again after leaving the
battery in a place with a temperature of 18?
(64?) for more than 30 minutes.
- Read the voltage immediately after the
switch is pressed. When 0.8 Seconds have
passed after the switch is pressed, the
automatic power off function starts and
resistance applied to the battery will cease.
The voltage of the battery will be 2.5 V or
more.
- Press the switch at least 3 times before
reading the voltage. If the battery
temperature has just returned to 18?
(64?), the voltage may be unusually high
for the first or second voltage reading.
Installation
- Install door control transmitter module
Notice:
Take extra care when handling these precision
electronic components.
- Install transmitter housing cover
- Install the transmitter housing cover to the
transmitter housing case.
- Check that the transmitter's led illuminates 3 times
when the switch is pressed 3 times.
Ok:
transmitter's led illuminates 3 times when
switch is pressed 3 times.
Read data list
Hint:
Using the intelligent tester's data list allows switch,
actuator and other item values to be read without
removing any parts. Reading the data list early in
troubleshoot ...
Inspection
Inspect power window regulator master
switch assembly (door control switch)
Measure the resistance of the door control switch.
Standard resistance
If the result is not ...
Other materials:
Check for intermittent problems
Check for intermittent problems
Hint:
A momentary interruption (open circuit) in the connectors
and/or wire harness between the sensors and ecus can
be detected by using the ecu data list function of an
intelligent tester.
Turn the ignition switch off and connect the
intelligent test ...
Light bulbs
You may replace the following
bulbs by yourself. The
difficulty level of replacement
varies depending on
the bulb. If necessary bulb
replacement seems difficult
to perform, contact your
Toyota dealer.
