Some packs use two cooling fans; P0A96 reports an open or general fault in the control circuit of the second one. Ford documents it code-exact: on 2005–12 Escape Hybrid and 2006–11 Mariner Hybrid the traction battery control module may store P0A96, often together with P0A81 for fan 1, and the repair is to replace both high-voltage battery fans with a kit (about 3 hours, pack removal included). Ford notes the code alone usually causes no noticeable symptom. CARB requires the electronic outputs used for battery thermal management to be monitored. Short-circuit faults on fan 2 are P0A99 and P0A9A. If one fan fails, cooling capacity drops and power may be limited in heat.

Likely causes

Fan 2 motor or electronics failed (Ford replaces both fans)
Loose connector or broken wire to fan 2
Blown fan fuse

Symptoms

  • Code found during other diagnosis, often no complaint
  • Check engine or hybrid warning
  • Reduced hybrid power in hot conditions
