Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Control Module Wake-up Circuit Low
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
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.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
