DTC B2141 [DYNAMIC STABILITY CONTROL (DSC)]

id0402b2803800

Note

• The DSC indicator light illuminates and remains illuminated, and DTC B2141 (vehicle data not recorded) is stored in the memory only when the ignition switch is turned to the ON position for the first time after DSC HU/CM or DSC CM replacement. Since the vehicle data is downloaded from the PCM via a CAN line when the ignition switch is turned to the ON position, DTC B2141 is only stored as a past malfunction when the ignition switch is turned off and then turned to the ON position.
