Circuit/System Verification

  1. Verify P0C32, P0A81, P0A84, P0A85 or P0A7E are not set.
  2. Ignition On, verify with a scan tool that the Phase U DC/AC Inverter Temperature 1 is less than 118°C (245°F).
    • If greater than 118°C (245°F), inspect for proper operation of the hybrid battery cooling fan and ducts.
    • If the hybrid cooling system tests normal, Reprogram K59 starter generator control module. If the DTC resets replace the K59 starter generator control module.
