Toyota RAV4 (XA40) 2013-2018 Service Manual: Terminals of ecu
- Skid control ecu
Hint:
*1: W/ 16-inch disc
*2: W/ downhill assist control
*3: For 2wd (w/ auto lsd)
- Check skid control ecu
- Disconnect the a19 ecu connector.
- Measure the voltage and resistance of the wire harness side connector.
Hint:
The voltage cannot be measured with the connector connected to the skid control ecu as the connector is water resistant.
Hint:
*1: W/ 16-inch disc
*2: W/ downhill assist control
*3: For 2wd (w/ auto lsd)
If the result is not as specified, there may be a malfunction on the wire harness side.
- Check instrument panel junction block (main body ecu)
- Disconnect the id junction block connector.
- Measure the resistance of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
- Reconnect the id junction block connector.
- Measure the voltage of the wire harness side connector.
If the result is not as specified, the junction block (ecu) may be a malfunction.

Diagnosis
If the skid control ecu detects a malfunction, the abs,
vsc and brake warning lights and the slip, downhill
assist control and auto lsd indicator lights come on in
accordance with t ...

Front passenger side - side airbag sensor assembly initialization incomplete
Description
The side airbag sensor rh consists of parts including the diagnostic circuit
and the lateral deceleration
sensor.
When the center airbag sensor receives signals from the lateral deceleration
sensor, it determines
whether or not the srs should be activated.

Catalyst system efficiency below threshold (bank 1)
Monitor description
The ecm uses sensors mounted in front of and behind the three-way catalytic
converter (twc) to
monitor its efficiency.
The first sensor, the air-fuel ratio (a/f) sensor, sends pre-catalyst
information to the ecm. The second
sensor, the heated oxygen (ho2) sensor, se ...
The rear cross traffic
alert function
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 11.5 Ft. (3.5 M)
from the side of the vehicle
The first 1.6 Ft. (0.5 M) from the
side of the vehicle is not in the
detection area
Approximately 9.8 Ft. (3 M) fr ...
