DTC
|
C1436
|
Malfunction in Yaw Rate Sensor
|
DESCRIPTION
The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).
When the skid control ECU (brake booster with master cylinder assembly) detects improper installation of the yaw rate and acceleration sensor (airbag sensor assembly) or an abnormality in the difference between the yaw rate sensor value and the control value estimated based on the acceleration sensor, steering angle sensor and speed sensor signals, DTC C1436 is stored.
DTC No.

(b) Check the yaw rate sensor output value displayed on the Techstream.
Result
|
Proceed to
|
NG (The yaw rate sensor (airbag sensor assembly) output value is 0 deg/s when the vehicle is stationary, but the value fluctuates when turning.)
|
A
|
NG (The yaw rate sensor (airbag sensor assembly) output value is not 0 deg/s when the vehicle is stationary.)

|
CHECK AIRBAG SENSOR ASSEMBLY INSTALLATION
|
(a) Turn the power switch off.
(b) Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly.

OK:
The yaw rate and acceleration sensor (airbag sensor assembly) is tightened to the specified torque.
The yaw rate and acceleration sensor (airbag sensor assembly) is not tilted.
