These signals are used to control the S,, TRC, -TRC, VSC, UTO LSD, downhill assist and hill-start assist control systems. This speed sensor contains a sensor IC, which consists of 2 MREs (Magnetic Resistance Element). The speed sensor rotor, which consists of 48 sets of N and S poles that are arranged in a circle, is integrated with the inner race of the hub bearing. To detect the rotation direction, the output waves are used to determine the relationship of the pulses that are generated by 2 MREs. Upon receiving this signal, the sensor IC outputs a forward or backward wave to the ECU.

2 66 RKE CONTROL VEHICLE STILITY CONTROL SYSTEM DTC No. DTC Detection Condition Trouble rea C0210/33 C0215/34 C1238/38 C1239/39 When any of the following conditions is detected: 1. t a vehicle speed of 6 mph (10 km/h) or more, pulses are not input for 1 second. 2. Momentary interruption of the speed sensor signal occurs at least 255 times when switching the ignition switch ON and OFF. 3. Continuous noise occurs in speed sensor signals at a vehicle speed of 12 mph (20 km/h) or more. 4. Speed sensor signal circuit is open for 0.12 seconds or more of the wheel sensors detect normal reversing signals, and the other wheel sensor detects malfunction signals 75 times with IG ON while reversing at 3 km/h. 6. Rotating direction of each wheel changes 7 times within seconds with IG ON while driving at 10 km/ h or more. 7. Rotating direction of one of the wheels is not the same as that of the other wheels for 1 second while driving at 30 km/h or more. 8. Reversing signal is output for 1 second or more while driving at 100 km/h or more. 9. Rotating direction of one of the wheels is not detected normally, and the rotating direction of each of the other wheels is not the same for 1 second while driving at 30 km/h or more. Continuous noise occurs in speed sensor signals when vehicle speed is 12 mph (20 km/h) or more for 5 seconds or more. HINT: DTC C0210/33 and C1238/38 are for the right rear speed sensor. DTC C0215/34 and C1239/39 are for the left rear speed sensor.
