DTC 13 - Open Motor Circuit Or Abnormal Throttle Angle Sensor Signal: Notes

The CCM applies voltage and ground to both the open side and close side of DC servo motor as driving conditions demand changing throttle angles.

The CCM also supplies a reference voltage and ground to throttle angle sensor inside the cruise control actuator. The throttle angle signal is sent to CCM. The CCM uses this information to judge throttle angle and throttle movement whenever DC servo motor is operated.
