Code result
P24F1
Control Module Wake-up Circuit High
Moderate severity
What it means
The wake-up input reads above the expected range — typically a short to battery voltage. The module sees a permanent wake-up request, never enters sleep mode and drains the battery while parked.
Is it safe to drive?
