P1570

Circuit Description

This diagnostic test indicates that cruise control and traction control are active at the same time. It is a protective measure to disable the cruise control for example, when traveling on icy roads and traction control requests a maximum torque of less than 1%. Under these conditions DTC P1570 is set and the cruise control will be disengaged. The driver should be advised why the cruise disengaged. Clear the DTC and road test vehicle to verify normal operation.
