Can drive — fix at your convenience.
This code is set when the computer sees a problem with the 'coast' signal from the cruise control switch, the input that lets you gradually slow down while cruise is active. The usual culprits are a worn cruise control switch, damaged wiring or connectors near the steering wheel, or a fault in the control module. Repairs are generally simple and most often involve servicing the switch or its wiring.
$90 – $350
Varies by vehicle and root cause.
Yes. The code only affects cruise control, so your car is safe to drive normally. You just may not be able to use the coast or full cruise functions reliably until it's repaired.
Expect roughly $90 to $350. Cleaning or replacing the switch is cheaper, while wiring repairs or replacing a control module costs more.
No, it's low severity. It doesn't threaten your engine, transmission, or safety, but it's worth fixing so your cruise control behaves properly.
The coast signal lets you gently lower your set speed while cruise control is on. With this code, that input isn't reaching the computer correctly, so the coast feature stops working.
