OBD-II Code
P0570
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$30–$400
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
$30 (DIY brake switch replacement) to $400 (TIPM repair or pedal-bracket replacement on a RAM).
P0570 is set when the cruise control system reads an implausible state on the brake-switch input — typically the stop-lamp / brake-light switch that doubles as the cruise-disengage signal.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Normal brake switch behavior
pedal up (not pressed) reads 0V on the cruise input (open circuit) and 12-14V on the stop-lamp input (or the inverse on dual-channel switches, where one pole opens as the other closes); pedal down (pressed) reads battery voltage on the cruise input (closed circuit) and 0V on the stop-lamp input. Cheapest-first ladder: scan-tool live data for brake-switch state and compare against actual pedal position — at rest the switch should read "not applied"; lightly touch the pedal and watch for a clean transition to "applied" within a few mm of travel. If the state flickers, chatters, or reports both "applied" and "not applied" simultaneously (common on dual-channel switches where one pole fails), the switch is worn. Backprobe both poles of the switch with a DMM, work the pedal slowly, and watch for clean make/break transitions — anything below 11V on the supply side or above 0.5V on the open side is a failing switch. Inspect the switch's bumper/plunger on the pedal bracket; the plastic plunger commonly cracks or wears short and the switch reads "applied" at rest. Expensive-misdiagnosis caveat: a flickering brake switch will not only kill cruise control but will trigger torque-management and transmission shifts, ABS event flags, and on some platforms (Toyota in particular) an unintended-acceleration concern in the freeze frame — verifying the switch is healthy before chasing transmission or throttle codes saves hours.

- 2005-2010Toyota and Lexus across multiple platforms (Camry, Avalon, RAV4, ES350, IS250) are the textbook P0570 / brake-switch case — the OEM brake switch plunger wears short, the switch reads "applied" at rest, cruise won't engage, and the ECM logs the code; Toyota issued multiple TSBs and offered an extended warranty / recall on affected VINs after the 2009-2011 unintended-acceleration investigations.
- 2009-2014Ford F-150 (and similar-era Edge, Explorer, Expedition) commonly throws P0570 from stop-lamp switch wear at the pedal bracket — the cheap fix is a $25 switch from any parts store, but the part has to seat perfectly against the pedal arm or the code returns.
- 2007-2013Chevy/GMC trucks (Silverado, Sierra, Tahoe, Suburban) throw P0570 from the same generic stop-lamp switch wear plus occasional brake-pedal-position sensor failures on platforms equipped with electronic throttle.
- 2010-2017RAM 1500/2500 also commonly throws P0570 from the TIPM-routed brake switch circuit when the under-hood module corrodes the relay contacts.
