Toyota RAV4 (XA40) 2013-2018 Service Manual: Abs and traction actuator (skid control ecu) communication stop mode
Description

Wiring diagram

Inspection procedure
Notice:
- Turn the ignition switch off before measuring the resistances
of the main wire and the branch
wire.
- After the ignition switch is turned off, check that the key
reminder warning system and light
reminder warning system are not in operation.
- Before measuring the resistance, leave the vehicle for at least
1 minute and do not operate the
ignition switch, any switches or doors. If doors need to be opened in order
to check
connectors, open the doors and leave them open.
Hint:
Operating the ignition switch, any switches or any doors triggers related ecu
and sensor communication
with the can, which causes resistance variation.
- Check can bus line disconnection (abs and traction actuator branch
wire)

- Disconnect the a19 abs and traction actuator (skid
control ecu) connector.
- Measure the resistance of the wire harness side
connector.
Standard resistance

- Check wire harness (abs and traction actuator - battery and body
ground)

- Disconnect the a19 abs and traction actuator (skid
control ecu) connector.
- Measure the resistance of the wire harness side
connector.
Standard resistance
- Measure the voltage of the wire harness side connector.
Standard voltage 

Replace abs and traction actuator (skid control ecu)

General information
A large number of ecu controlled systems are used in the
rav4. In general, ecu controlled systems are considered to
be very intricate, requiring a high level of technical knowledge
to troubleshoot. However, most problem checking procedures
only involve inspecting the ecu controlled system's circ ...
Transmitter id
Description
Hint:
It is necessary to perform the procedure to identify the tire pressure
monitor valve that is malfunctioning
because it cannot be identified by the output dtc.
