CUSTOMER CONCERN The vehicle was towed in with a no-start condition and DTC P0AA6 for a high-voltage isolation fault. CAUSE The 12-volt auxiliary battery measured only 8.3 volts and would not retain a charge; the confirmed report also found sleep-current draw at approximately 0.03 mA. CORRECTION Remove and replace the failed 12-volt auxiliary battery, clear DTC P0AA6, and verify the vehicle enters READY mode normally.

CUSTOMER CONCERN Customer states the malfunction indicator light is on. EVAP small-leak DTC P0456 is stored. CAUSE Smoke testing with a soapy-water check confirmed a crack in the plastic fuel-pump housing below the retaining ring. CORRECTION Remove and replace the fuel-pump assembly.
