Toyota RAV4 (XA40) 2013-2018 Service Manual: Diagnosis system
- Bus check
- Select "bus check" from the "obd / mobd menu" screen.
Hint:
The ecus and sensors that are properly connected to the can communication system can be displayed using the intelligent tester via can vim.
- Press "enter" on the intelligent tester via can vim.
- The screen displayed the ecus and sensors that are properly connected to the can communication system.
Hint:
There is a communication stop in the system of any properly connected ecus or sensors that are not displayed (see page ca-10).
- Check installed systems (ecus and sensors) that use can communication
- System (ecus and sensors) that use can communication vary depending on the vehicle's optional settings. Check which systems (ecus and sensors) are installed on the vehicle.
- Dtc table by ecu
Hint:
- In the can communication system, can communication system dtcs output by the ecu can be displayed by using the intelligent tester.
- If can communication system dtcs are output, the
trouble cannot be determined solely from the dtcs.
Perform troubleshooting according to "how to proceed with troubleshooting" (see page ca-8).
- Abs and traction actuator (skid control ecu)
Hint:
Dtc communication uses the can communication system.
- Power steering ecu
Hint:
Dtc communication uses the can communication
system.
- Ecm
Hint:
Dtc communication uses the can communication
system.
- Air conditioning amplifier for vehicle with air conditioning (automatic air conditioning system and manual air conditioning system).
Hint:
Dtc communication uses the can communication
system.
- Combination meter ecu
Hint:
Dtc communication uses the can communication
system.
- 4Wd control ecu
For vehicle with 4wd only.
Hint:
Dtc communication uses the can communication
system.
- Main body ecu
Hint:
The center airbag sensor is connected to the can communication system but can communication dtcs are not output.
- Center airbag sensor
Hint:
The center airbag sensor is connected to the can communication system but can communication dtcs are not output.
- Dtc combination table
Hint:
- O: Outputs under condition shown in table above
- X: not output
Hint:
- O: Outputs under condition shown in table above
- X: not output
- Check the stop mode by using the results of the bus check for the center airbag sensor (see page ca- 69) and main body ecu (see page ca-64).
- Perform troubleshooting according to the combination of dtcs output.
- Abs and traction actuator (skid control ecu) communication stop mode: (see page ca-42)
- Power steering ecu communication stop mode: (see page ca-49)
- Steering angle sensor communication stop mode: (see page ca-52)
- Yaw rate sensor communication stop mode: (see page ca-55)
- Ecm communication stop mode: (see page ca-58)
- Air conditioning amplifier communication stop mode: (see page ca-45)
- Combination meter ecu communication system: (see page ca-67)
- 4Wd control ecu communication stop mode: (see page ca-72)
Check 4wd control ecu (for 4wd)

Replacement
Replace timing chain cover oil seal
Hint:
There are 2 methods to replace the oil seal.
If the timing chain cover is removed from the
cylinder block:
Using a screwdriver and hammer, tap out the
oil seal.
Apply multi-purpose grease to the lip of a new
oil seal.
