DTC C1436: Yaw Rate Sensor Malfunction [08/2015 - ]: Procedure

1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON.
3. Select the Data List using the Techstream. Refer to DATA LIST / ACTIVE TEST [08/2015 - ] .
   ABS/VSC/TRAC
   
   

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Yaw Rate Sensor	Yaw rate sensor / Min.: -128 degrees/s, Max.: 127 degrees/s	Vehicle stopped: 0 degrees/s Turning right: -128 to 0 degrees/s Turning left: 0 to 127 degrees/s	-

4. Check that the yaw rate and acceleration sensor (airbag sensor assembly) output value displayed on the Techstream.

   Result

   Result	Proceed to
   NG (The yaw rate and acceleration sensor (airbag sensor assembly) output value is 0 degrees/s when the vehicle is stationary, but the value fluctuates when turning.)	A
   NG (The yaw rate and acceleration sensor (airbag sensor assembly) output value is not 0 degrees/s when the vehicle is stationary.)	B
   OK	C

   HINT: 

   If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step before replacing parts. Refer to PROBLEM SYMPTOMS TABLE [08/2015 - ] .

C → See step   6 

A: Go to next step 

1. Turn the ignition switch off.
2. Drive the vehicle straight ahead at 50 km/h (31 mph) or more for at least 30 seconds.
3. Check that the steering wheel is correctly centered while driving straight ahead.

   HINT: 

   If front wheel alignment and steering are adjusted as a result of an off-center steering wheel, acquire the yaw rate and acceleration sensor zero point again after the adjustments are completed.

   OK

   The steering wheel is correctly centered.

NG → See step   7 

OK: Go to next step 

1. Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly. Refer to INSTALLATION [08/2015 - ] .

   OK

   The sensor should be tightened to the specified torque.

   The sensor should not be installed in a tilted position.

   HINT: 

   If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step before replacing parts. Refer to PROBLEM SYMPTOMS TABLE [08/2015 - ] .
