Toyota RAV4 (XA40) 2013-2018 Service Manual: Stuck in deceleration sensor
Description
The skid control ecu receives signals from the yaw rate and deceleration sensor via the can communication system.
The yaw rate sensor has a built-in deceleration sensor and detects the vehicle's condition using 2 circuits (gl1: g sensor 1, gl2: g sensor 2).
If there is trouble in the bus lines between the yaw rate and deceleration sensor and the can communication system, dtc u0123/62 (malfunction in can communication with the yaw rate sensor) and u0124/95 (malfunction in can communication with the deceleration sensor) are output.
These dtcs are also output when the calibration has not been completed.
Dtcs c0371/71 and c1279/79 are deleted when the yaw rate and deceleration sensor sends a yaw rate and/or deceleration signal or test mode ends. Dtcs c0371/71 and c1279/79 are output only in test mode.
Wiring diagram
Refer to dtc c1210/23, c1336/39 (see page bc-89).
Inspection procedure
Notice:
When replacing yaw rate and deceleration sensor, perform zero point calibration (see page bc- 24).
Hint:
When dtc u0123/62, u0124/95 or u0126/63 is output together with dtc c1232/32, c1234/34, c1243/ 43, c1244/44, c1245/45, or c1387/97, inspect and repair the trouble areas indicated by dtc u0123/62, u0124/95 or u0126/63 first.
- Check dtc
- Clear the dtc (see page bc-47).
- Turn the ignition switch off.
- Turn the ignition switch on again and check that no can communication system dtc(s) is output.
- Drive the vehicle at a speed of 30 km/h (19 mph) or more and check that no dtcs are output.
Result 
- Check yaw rate sensor installation
- Check that the yaw rate sensor has been installed correctly (see page bc-211).
Ok: the sensor is tightened to the specified torque.
The sensor is not tilted.
- Check wire harness (yaw rate sensor - battery and body ground)
- Disconnect the k6 sensor connector.
- Measure the voltage of the wire harness side connector.
Standard voltage 
- Measure the resistance of the wire harness side connector.

Replace yaw rate sensor
