Code P24F0: Control Module Wake-up Circuit Low
Diagnostic & Technical Explanation
Code P24F0 (Control Module Wake-up Circuit Low) sets when a control module's wake-up input, the signal that brings the module out of sleep mode when the vehicle is unlocked or another module requests network activity, reads open, shorted low, or shorted high. Causes are a failed wake-up relay or diode, a corroded connector at the module, or damaged wiring on the wake-up line shared with other body/network modules.
