DESCRIPTION The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via CAN communication. The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If a communication error with the yaw rate and acceleration sensor (airbag sensor assembly) is detected, DTCs U0123 (Lost Communication with Yaw Rate Sensor Module) is stored. The DTCs are also stored when the calibration has not been completed.
CAUTION / NOTICE / HINT NOTICE:
HINT: When U0123 is output together with C1336, inspect and repair the trouble areas indicated by U0123 first. Click here PROCEDURE
(a) Turn the ignition switch off. (b) Check that the yaw rate and acceleration sensor (airbag sensor assembly) has been installed properly. for Column Shift Type: Click here for Floor Shift Type: 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.
