Diagnostic trouble code information

Condition

The steering wheel angle sensor has two circuits each with 4 LEDs and 4 receptors which read off their individual code wheel. One circuit measures the steering wheel angle and the other measures steering wheel revolutions. If the steering wheel angle sensor (SAS) control unit registers that the wires for the signals R1/R2/R3/R4 between the steering wheel angle sensor control unit and the steering wheel angle sensor have short-circuited to each other, diagnostic trouble code SAS-0022 is set.
