P0570
Cruise Control Accelerate Signal
Cruise / speed control
Generic OBD-II
Low
What it means
P0570 indicates a fault in the cruise control's accelerate (set/resume) signal — the input that tells the system to build speed. The result is that cruise control won't set or hold a speed. It's a convenience-system electrical fault and doesn't affect how the engine runs or your ability to drive normally.
Low
Can I keep driving? Fine to drive — only cruise control is affected; the engine and normal driving are unchanged.

- If the switch and wiring are good, suspect the cruise control module. Clear and re-test.

Is it safe to drive with P0570?+
Yes. Only the cruise control is affected — the engine runs normally and braking, steering, and acceleration are unchanged.
