Code result
P24F0
Control Module Wake-up Circuit Low
Moderate severity
What it means
The wake-up input on the control module reads stuck low — usually a short to ground or a permanently asserted wake signal. The module either keeps waking up unnecessarily and drains the battery, or it cannot distinguish a real wake event from the stuck low level.
Is it safe to drive?
Use caution
The vehicle is usually drivable for short distances, but the problem can worsen or affect emissions. Diagnose and repair as soon as practical.
