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.

Description
The rear airbag sensor lh 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.
