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) and U0151 (Lost Communication With Restraints Control Module) are stored. The DTCs are also stored when the calibration has not been completed.
CAUTION / NOTICE / HINT NOTICE:
HINT: When U0123 and/or U0151 is output together with C1336, inspect and repair the trouble areas indicated by U0123 and/or U0151 first. Click here
PROCEDURE
(a) Enter the following menus: Chassis / ABS/VSC/TRAC/EPB / Utility / Test Mode. (b) Perform zero point calibration of the yaw rate and acceleration sensor. Click here
(a) Turn the engine switch off. (b) Enter the following menus: Chassis / ABS/VSC/TRAC/EPB / Utility / Signal Check. (c) Using the Techstream, perform a Test Mode (Signal Check) inspection sensor check and check that all Test Mode (Signal Check) inspection items change from incomplete to complete. Click here
OK: All Test Mode (Signal Check) inspection items change from incomplete to complete
(a) Turn the engine switch off. (b) 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.
(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. OK: The yaw rate and acceleration sensor (airbag sensor assembly) output value is normal.
