Code result
P2532
Ignition Switch Run Position Circuit High
Moderate severity
What it means
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.
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.
