SAS-0001

SAS-0001: LED Group 1 Circuit, Signal Too Low
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 control unit registers that the current passing through the LED group circuit is too low, diagnostic trouble code SAS-0001 or SAS-0025 is set, depending on the group.
