CUSTOMER CONCERN Vehicle is towed in with a no-start condition and Hybrid Battery Voltage System Isolation Fault DTC P0AA6. CAUSE The electric A/C compressor had an internal high-voltage isolation fault. CORRECTION Disable the high-voltage system, remove and replace the electric A/C compressor, clear DTC P0AA6, and verify isolation resistance and READY operation.

CUSTOMER CONCERN Lean-condition faults are present and measured fuel pressure is only 15 psi. CAUSE The in-tank fuel-pump seal was torn, allowing the pump to draw air and produce insufficient fuel pressure. CORRECTION Remove and replace the fuel-pump module and damaged seal, clear the lean-condition DTCs, and verify normal fuel pressure and engine operation.

CUSTOMER CONCERN The check-engine and hybrid-system warning lights are on with DTC P0A80 stored. CAUSE Hybrid-battery testing confirmed deterioration inside the high-voltage battery pack. CORRECTION Remove and replace the failed high-voltage hybrid battery pack.
