Toyota RAV4 (XA40) 2013-2018 Service Manual: Precaution
- Troubleshooting precaution
- When there are malfunctions in the contact points of the terminals or installation problems with any parts, removal and installation of the suspected problem parts may return the system to its normal condition either entirely or temporarily.
- In order to determine the location of the malfunction, be sure to check the conditions at the time the malfunction occurred through data such as dtc and freeze frame data outputs. Record this information before disconnecting any connectors and removing or installing any parts.
- Since the vehicle stability control system may be influenced by malfunctions in other systems, be sure to check for dtcs in other systems.
- Be sure to remove and install the abs and traction actuator and each sensor with the ignition switch off, unless specified in the inspection procedures.
- When removing and installing the abs and traction actuator and each sensor, be sure to check that the normal display is output during a test mode inspection and a dtc output inspection after reinstalling all the parts.
- After replacing the abs and traction actuator and/ or yaw rate sensor, be sure to perform yaw rate and deceleration sensor zero point calibration (see page bc-24).
- The can communication system is used for data communication between the skid control ecu, the steering sensor and the yaw rate sensor (the deceleration sensor is included). If there is trouble in the can communication line, the dtc of the communication line is output.
- If the dtc of the can communication line is output, repair the malfunction in the communication line and then troubleshoot the vehicle stability control system.
- Since the can communication line has its own length and route, it cannot be repaired temporarily with a bypass wire, etc.

Diagnosis system
Description
The center airbag sensor controls the functions of the
supplemental restraint system (srs) on the vehicle.
Data of the srs can be read in the data link connector
3 (dlc3) of the vehicle. When the system seems to be
malfunctioning, use the intelligent tester to check for a

Srs warning light does not come on
Description
The srs warning light is located on the combination meter.
When the srs is normal, the srs warning light comes on for approximately 6
seconds after the ignition
switch is turned from off to on, and then goes off automatically.
If there is a malfunction in the srs, the srs warni ...

Hint:
The abs and traction actuator (skid control ecu)
detects and stores steering sensor and yaw rate
sensor dtcs and performs dtc communication by
receiving information from the steering sensor and
yaw rate sensor.
