Drive with caution — fix soon.
This code means the computer detected a lower-than-expected voltage on the cruise control multi-function input A circuit. It usually points to a short to ground, damaged wiring, or a faulty cruise control switch. It's a common, repairable issue that typically comes down to a wiring or switch fix rather than major engine repair.
$100 – $350
Varies by vehicle and root cause.
Usually yes. The engine runs normally, but cruise control may not work, so be prepared to control your speed manually until it's repaired.
Most repairs run between $100 and $350, depending on whether it's a wiring or connector repair versus replacing the cruise control switch or module.
It's a moderate issue. It won't harm your engine, but the low-circuit reading usually points to a short or switch fault that's worth checking soon.
A low reading often comes from a wire shorted to ground or a failing switch pulling the voltage down. A technician can test the circuit to find the exact cause.
