Diagnose soon
Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
Ignition Switch Run Position Circuit High
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 ignition switch Run-position input reads stuck high — short to battery voltage or open switch return. The ECM cannot detect when the operator turns the switch back to off/accessory, so module sleep and accessory power timeouts do not work correctly.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
