P0570 code meaning
Cruise Control Accelerate Signal
What P0570 means
Cruise control buttons are almost always a resistor ladder on one or two signal lines, each button giving its own voltage; the module reading it (GM and Saab from about 2010: the body module; FCA: steering column module or PCM) sends the button state to the engine module over CAN. CARB names cruise control as the example of an emission-neutral diagnosis – it is simply switched off – so GM lists all these codes as type C and Ford as non-MIL: no warning lamp, the engine runs normally. P0570 classically concerns the accelerate (plus) button. Ford's 2023 diesel uses it differently, only with adaptive cruise: the CAN message with the maximum acceleration request from the radar module to the engine module is faulty, checked every 10 ms, fault after 0.1 s. GM does not use P0570 (resume and accelerate share P0567).
P0570 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0570
- Cruise control does not accelerate, adaptive cruise unavailable
- Cruise control locked out
- No check engine light, engine runs normally
Common causes of P0570
- PossibleAccelerate button faulty (conventional systems)
- PossibleFord adaptive cruise: CAN fault or software of radar module or PCM
- PossibleContact problem in steering wheel switch or clockspring
- Less likelyModule faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0570 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 70 | The exact fault in that area. |
What to do next
- Note P0570 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0570
What does P0570 mean?
P0570 means "Cruise Control Accelerate Signal". Cruise control buttons are almost always a resistor ladder on one or two signal lines, each button giving its own voltage; the module reading it (GM and Saab from about 2010: the body module; FCA: steering column module or PCM) sends the button state to the engine module over CAN. It is a generic code, so it means the same on every make.
Is it safe to drive with P0570?
P0570 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0570 fail an emissions test?
P0570 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0570 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will P0570 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
