Loss of KAM Power — Open Circuit

on 2010 Ford Taurus 3.5L V6 EcoBoost · AWD

What this code means

The PCM has detected a loss of Keep Alive Memory (KAM) power. The KAM circuit maintains battery voltage to the PCM to preserve adaptive learning values, fuel trim data, and DTC history when the engine is off.

Symptoms

  • Check Engine Light
  • Poor idle after battery reconnect
  • Transmission shifting harshly initially
  • Loss of stored DTCs
  • Fuel economy temporarily affected

Common causes

  • Battery recently disconnected
  • Blown KAM fuse
  • Corroded battery cable or terminal
  • Wiring issue in KAM circuit
  • Faulty PCM power relay

Diagnostic steps

  1. Check KAM fuse
  2. Inspect battery terminals for corrosion
  3. Test battery voltage
  4. Check wiring from battery to PCM KAM circuit
  5. Verify PCM power relay operation

Repair notes

Replace blown KAM fuse. Clean battery terminals. Repair wiring. Allow PCM to relearn after fix.
