In the event of a mechanical fault or malfunction in the front right circuit, diagnostic trouble code C1376 will be set. The TCS and ABS functions will
be disabled and the warning lamps for ABS, brakes and TCS OFF will light up as well as the central warning lamp.
The rear left wheel sensor sends a wheel speed signal to pin 9 on the control module. The sensor is grounded via pin 8.
The rear right wheel sensor sends a wheel speed signal to pin 2 on the control module. The sensor is grounded via pin 1.
The wheel sensors are integrated into the wheel hubs and consist of an inductive sensor with 29 teeth.
The inductive sensor works like a small alternator, the sine-wave voltage of which increases with increasing wheel speed. The sine-wave voltage
alternates between positive and negative polarity, which is achieved by alternate teeth and gaps on the toothed wheel. By measuring the frequency, the
control module can determine the speed of each wheel.
