CUSTOMER CONCERN The vehicle will not start, ignition power is present, and the scan tool cannot communicate with any control module. CAUSE Spread terminals in the data link connector prevented reliable contact with the scan-tool connector. DLC terminal 16 had battery voltage and terminals 4 and 5 had good grounds. CORRECTION Repair the spread data link connector terminals and verify the scan tool communicates with the vehicle modules and the vehicle starts normally.

CUSTOMER CONCERN The check-engine light is on with DTC P0441 for incorrect EVAP purge flow. CAUSE The confirmed repair identified a failed canister purge control solenoid valve. CORRECTION Remove and replace the failed canister purge control solenoid valve, clear DTC P0441, and verify the EVAP monitor completes without resetting the code.

CUSTOMER CONCERN The air conditioning blows cold with the gasoline engine off but stops cooling when the engine runs. CAUSE The confirmed repair identified lost air-conditioning servomotor initialization as the cause of the temperature-control problem. CORRECTION Perform the air-conditioning servomotor initialization with the scan tool and verify cold air is maintained with the gasoline engine both off and running.

CUSTOMER CONCERN The vehicle intermittently will not enter Ready mode even though the instrument cluster illuminates. Cycling the start switch four or five times eventually allows it to start, and no DTCs are stored. CAUSE The confirmed repair identified a failed high-voltage battery pack as the source of the intermittent no-Ready condition. CORRECTION Remove and replace the failed high-voltage battery pack and verify the vehicle enters Ready mode consistently through repeate

CUSTOMER CONCERN The fuel door intermittently will not open and the fuel tank is difficult to fill. CAUSE The charcoal canister was restricted, preventing the fuel tank from venting normally before the fuel door opened and during refueling. CORRECTION Remove and replace the restricted charcoal canister and verify the fuel door opens normally and the tank accepts fuel without restriction.

CUSTOMER CONCERN The vehicle will not charge and stores DTCs C1109, C118C-6, U1000, B142A, B2193, P0A1B, P0A8D, P3247, U1027-16, U1027, B2891, U0142-16, and P2891-19. CAUSE The confirmed repair identified failures in the EV charging-port plug and the Power Delivery Module. CORRECTION Remove and replace the failed EV charging-port plug and Power Delivery Module, clear the stored DTCs, and verify normal charging operation.

CUSTOMER CONCERN The check-engine light is on with DTC P012800 indicating that engine coolant temperature remains below the thermostat's specified operating range. CAUSE The engine coolant thermostat failed and did not regulate coolant temperature to the specified range. CORRECTION Remove and replace the engine coolant thermostat, clear DTC P012800, and verify coolant temperature reaches and maintains the specified operating range.

CUSTOMER CONCERN After front-end collision repair, the air conditioning does not operate, DTC P0073 is stored, and ambient-temperature data remains fixed at 69°F with a 5-volt signal. CAUSE Rodent damage behind the front bumper chewed through the wiring harness leading to the ambient-air-temperature sensor. CORRECTION Repair the damaged ambient-air-temperature sensor wiring behind the front bumper, clear DTC P0073, and verify the temperature signal changes normally and A/C op

CUSTOMER CONCERN The instrument cluster, radio, and HVAC controls are inoperative, the scan tool cannot communicate with those modules, and DTCs U0155 and U0422 are stored. CAUSE The medium-speed CAN wiring leading to the HVAC module was damaged, interrupting communication with the affected modules. CORRECTION Repair the damaged medium-speed CAN circuits to the HVAC module, clear DTCs U0155 and U0422, and verify cluster, radio, HVAC, and scan-tool communication operation.

CUSTOMER CONCERN The engine misfires, lacks power, and may stall. The condition can occur with or without cylinder-misfire or lean DTCs. CAUSE The confirmed repair identified failed ignition coils and worn spark plugs as the source of the misfire and drivability symptoms. CORRECTION Remove and replace the failed ignition coils and spark plugs, clear any stored misfire DTCs, and road test to verify normal power and idle quality.
