DESCRIPTION This DTC is stored when the skid control ECU (brake actuator 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. The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle condition.
CAUTION / NOTICE / HINT NOTICE: After replacing or reinstalling the yaw rate and acceleration sensor (airbag sensor assembly), perform system variant learning and acceleration sensor zero point calibration. Click here PROCEDURE
(a) Connect the Techstream to the DLC3. (b) Turn the engine switch on (IG). (c) Enter the following menus: Chassis / ABS/VSC/TRAC/EPB / Data List. Chassis > ABS/VSC/TRAC/EPB > Data List
(d) Check the yaw rate and acceleration sensor (airbag sensor assembly) output value displayed on the Techstream.
(a) Turn the engine switch off. (b) Drive the vehicle straight ahead at 15 km/h (9 mph) or more for at least 1 second. (c) 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.
(a) Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly. Click here 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 installed in a tilted position.
