DIAGNOSIS TSB Revision ACTIVE STABILITY CONTROL SYSTEM (ASC) 35C-73 CIRCUIT OPERATION • Each wheel speed detecting section is a kind of a pulse generator. It consists of the encoder (plate on which the • The pulse signals generated by the wheel speed detecting section are sent to ASC-ECU. ASC-ECU uses the fre- . DTC SET CONDITIONS ASC-ECU monitors the signals from each wheel speed sensor • Missing wheel speed sensor signal value than the values of other wheel speed sensors. . PROBABLE CAUSES Current trouble • Excessive gap between the wheel speed sensor and the magnetic encoder for wheel speed detection • Wheel bearing malfunction detection • Adhesion of foreign materials on the wheel speed sensor wheel speed detection • Malfunction of wheel speed sensor for wheel speed detection • The number of poles on the magnetic encoder for wheel speed detection (the number of N-pole and S-pole) is Past trouble • When the DTC No. C100A is also set, perform the diagno- sis with a particular emphasis on the wiring harness and ing/Inspection Service Points • When DTC No. C100A is not set simultaneously, the follow- ings can be suspected. • Wheel(s) spinning |
