P2532 Ignition Switch Run Position Circuit High

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

P2532 means voltage is present on the run-position input when it should be absent, typically after key-off or while the network reports the ignition as off. A run feed backfed through another component, a relay with welded contacts or a wire touching a permanent battery feed can cause it. The module then cannot tell that the driver has switched off, stays awake and may drain the battery or delay its own shutdown tests. Ford includes P2532 in the 2014 BOSS 302S code table, without a MIL marker, whereas the low-side P2531 is flagged for the MIL there. No maker publishes voltages or timing. The open or general fault is P2530; the related run/start high fault is P2535.

Likely causes

Voltage backfeed into the run circuit through another component
Run relay with welded contacts
Run wire touching a permanent battery feed

Symptoms

  • Battery drained after the vehicle is parked
  • Modules or fans keep running after key-off
