Speed Control Actuator

The speed control actuator is connected to the SCP communication network. The speed control system is designed to maintain vehicle speed between 48 and 200 km/h (30 and 125 mph). If one of the bus wires becomes shorted to ground or voltage, or if some but not all termination resistors are lost, communications can continue at a degraded level. Check the SCP circuits 915 (PK/LB) and 914 (TN/OG) between the speed control actuator C122 and the DLC C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the SCP network, damage to the DLC C251, damage to the speed control actuator C122, or a problem in the in-line connector.
