Yaw Rate Sensor: Service and Repair
REPLACEMENTNOTICE: Do not separate the sensor from the bracket.
1. REMOVE CONSOLE PANEL UPPER REAR
2. REMOVE RR CONSOLE BOX
3. REMOVE YAW RATE SENSOR
a. Disconnect the yawed sensor connector.
b. Remove the 2 bolts and yaw rate sensor.
4. INSTALL YAW RATE SENSOR
a. Install the yaw rate sensor with the 2 bolts.
Torque: 12.5 Nm (127 kgf-cm, 9 ft. lbs.)
b. Connect the yaw rate sensor connector.
5. INSTALL RR CONSOLE BOX
6. INSTALL CONSOLE PANEL UPPER REAR
7. PERFORM YAW RATE SENSOR ZERO POINT CALIBRATION
8. PERFORM DECELERATION SENSOR ZERO POINT CALIBRATION
YAW RATE SENSOR DECELERATION SENSOR ZERO POINT CALIBRATION
HINT:
- When having replaced the yaw rate sensor, deceleration sensor or the ECU, make sure to perform yaw rate and deceleration sensors' zero point calibration. Be sure to complete this step 6. once it is started.
- During step (6), an unreplaced sensor also requires zero point calibration.
NOTE:
- While obtaining the zero point, keep the vehicle in stationary condition and do not tilt, move or shake the vehicle
- Be sure to perform this on a level surface (within an inclination of 1%).
a. Clear the zero points of the yaw rate and deceleration sensors.
1. Shift the shift lever to P range.
2. Turn the ignition switch ON in a stationary condition.
3. With the lit switch ON, using SST, repeat a cycle of short and open between terminals Ts and CG of DLC3 4 times or more within 8 sec. Check that the TRC OFF indicator light is lit indicating the recorded zero point is erased.

4. Turn the ignition switch OFF.
b. Obtain zero point of the yaw rate sensor.
1. Make the terminals Ts and CG of DLC3 disconnected.
2. Turn the ignition switch ON.
HINT: The vehicle should be in a stationary condition with the shift lever in P range.
3. Check that the lit TRC OFF indicator light turns off about 15 sec. after the ignition switch is turned ON.
HINT: Even if the ignition is not turned OFF in step (a) - (4) and remains ON, the yaw rate sensor zero point calibration can be completed. In this case, the TRC OFF indicator light is lit for about 15 sec. and then starts blinking. (Normal code).
4. After ensuring that the TRC OFF indicator light remains OFF for 2 sec., turn the ignition switch OFF.
HINT: If the ignition switch is not turned OFF in step (a) - (4), make sure that the TRC OFF indicator light blinks for 2 sec. Then turn the ignition switch OFF.
c. Perform deceleration sensor zero point calibration.
NOTE: After step b. (the yaw rate sensor zero point calibration), the VSC warning light goes off. At this time, if the vehicle is driven without performing step (c) (deceleration sensor zero point calibration), deceleration sensor zero point calibration malfunction will be detected and the VSC warning light will light up. Therefore, perform step (c) right after step (b).
1. Using SST; connect the terminals Ts and CG of DLC3.

2. Turn the ignition switch ON.
HINT: Place the vehicle in a stationary condition with the shift lever in P range.
3. After turning the ignition switch ON, check that the VSC warning light is lit for about 4 sec. and then starts quick blinking at 0.13 sec. intervals.
4. After confirming the blinking of the TRC OFF indicator light for 2 sec., turn the ignition switch OFF.
5. Remove the SST and make the terminals Ts and CG of DLC3 disconnected.
