Toyota RAV4 (XA40) 2013-2018 Service Manual: Precaution
- Tire pressure warning system precaution
- When the tire pressure warning light turns on,
immediately check the tire pressure of the tire and
adjust it to the specified value. (When the tire
pressure warning light circuit is open, the tire
pressure warning light flashes for 1 minute and then
illuminates.)
Notice:
Check the spare tire as well since this system
monitors the pressure of all tires.
Standard pressure:
220 kpa (2.2 Kgf/cm2, 32 psi)
- When the tire pressure warning light blinks, there is
a malfunction in the system. Check for dtcs.
- It is necessary to register the transmitter id in the
tire pressure warning ecu after replacing the tire
pressure warning valve and transmitter and/or tire
pressure warning ecu (see page tw-9).
- When replacing the tire pressure warning ecu:
- Using the data list, read the transmitter ids
registered in the ecu and make a note of them
before removing the tire pressure warning ecu.
- Register the transmitter ids after installing a new
tire pressure warning ecu.
- When replacing the tire pressure warning valve and
transmitter:
- Take a note of the 7 digit number (transmitter id)
written on the tire pressure warning valve and
transmitter when replacing it. Register the
transmitter ids in the tire pressure warning ecu
after replacing the tire pressure warning valve
and transmitter and installing the tires and
wheels on the vehicle.
Notice:
The transmitter id written on the tire
pressure warning valve and transmitter will
be unable to be read after installing it on the
tire and wheel.
- In case of tire and wheel replacement
- When tires and wheels are replaced, always be sure
to register the transmitter id correctly.
- Fail-safe function
- When a system malfunction occurs in the tire
pressure warning system, the tire pressure warning
light blinks and informs the driver of the system
failure.
- The result of this diagnosis is stored in the tire
pressure warning ecu.
- Precautions about the tire pressure:
- The tire pressure decreases naturally.
- In winter, tire pressure may decrease due to low
ambient temperature (tire pressure decreases by
approximately 10 kpa (0.2 Kgf/cm2, 1.45 Psi) for
every 10°c (50°f) drop in the ambient
temperature).
Therefore, the tire pressure warning is more
likely to operate if the tire pressure are not
adjusted appropriately.
If the daily temperature variation is large, adjust
the tires to a higher pressure suitable to cold
conditions.
This will reduce the likelihood of an incorrect tire
pressure warning operation.

Front occupant classification sensor lh collision detection
Description
Dtc b1785 is output when the occupant classification ecu receives a collision
detection signal sent by
the front occupant classification sensor lh when an accident occurs.
Dtc b1785 is also output when the front seat rh is subjected to a strong impact,
even if an actual
acc ...
