DIAGNOSIS TSB Revision ACTIVE STABILITY CONTROL SYSTEM (ASC) 35C-59 CAUTION • If there is any problem in the CAN bus lines, an incor- rect diagnostic trouble code may be set. Prior to this − CAN Bus Line Diagnostic Flow • Whenever ECU is replaced, ensure that the CAN bus lines are normal. • When the hydraulic unit (integrated with ASC-ECU) is replaced, always carry out the calibration of the steer-
and . OPERATION • The wheel speed sensor is a kind of a pulse generator. It consists of encoders (a plate on which north and south pole • The pulse signals, which the wheel speed sensor creates, are sent to ASC-ECU. ASC-ECU uses the frequency of the . DTC SET CONDITIONS ASC-ECU monitors the signals from each wheel speed sensor • Irregular change in the wheel speed sensor signal • Wheel speed sensor signal continuously indicates high value. . PROBABLE CAUSES Current trouble • Excessive gap between the wheel speed sensor and the wheel speed detection encoder • Adhesion of foreign materials on the wheel speed sensor AC901080AN Connector: D-133 D-133 (B) |
