CUSTOMER CONCERN Check-engine light is on with DTC P0011. CAUSE Testing confirmed a failed intake camshaft actuator solenoid. CORRECTION Remove and replace the failed intake camshaft actuator solenoid.

CUSTOMER CONCERN Vehicle will not restart and stores DTCs P0AFB, U0111 and U1897. CAUSE Diagnosis found a poor connection at the 36-volt battery-cable connector. CORRECTION Repair the 36-volt battery-cable connector and restore a secure electrical connection.

CUSTOMER CONCERN Customer states the passenger-front and both rear power door locks do not operate, while the driver-front lock works normally. No BCM DTCs are stored. CAUSE Gray and Tan lock-circuit voltage changed correctly when commanded, confirming the passenger-front and rear door-latch actuators had failed internally. CORRECTION Remove and replace failed passenger-front and both rear door-latch actuator assemblies. Verify lock and unlock operation from both switches and

CUSTOMER CONCERN Customer states the Service Charging System message is displayed. ECM DTC P0621 is stored. CAUSE L-terminal command and Orange-wire voltage testing confirmed the control circuit was operating but the alternator did not respond correctly, identifying an internal alternator failure. CORRECTION Remove and replace alternator. Clear DTC P0621 and verify charging-system output and L-terminal command response.

CUSTOMER CONCERN Customer states the traction-control warning light comes on intermittently. EBCM DTC C0561-71 is stored. CAUSE Traction-control switch input testing on the Brown/White circuit 1571 isolated an intermittent terminal connection at the traction-control switch connector. CORRECTION Clean and repair traction-control switch connector terminals, clear DTC C0561-71 and verify the BCM switch input remains in the enabled state.

CUSTOMER CONCERN Customer states the vehicle was parked for approximately two months and now stores DTCs P0AFB, P1A22, P1A26 and P1A29. CAUSE Campaign inspection confirmed the hybrid battery pack had failed after the extended storage period. CORRECTION Remove and replace hybrid battery pack under the applicable campaign. Clear hybrid-system DTCs and verify battery-system operation.

CUSTOMER CONCERN Customer states the check-engine light is on. DTC P0420 is stored. CAUSE Exhaust-manifold, misfire, coolant-consumption and fuel-trim checks confirmed the catalytic converter was below efficiency. CORRECTION Remove and replace catalytic converter. Clear DTC P0420 and verify catalyst-monitor operation.

CUSTOMER CONCERN Customer states the engine idles too high after the throttle-body bore was cleaned. No DTCs are stored. CAUSE Throttle-body cleaning changed the effective airflow at the learned throttle position, leaving the idle adaptation out of range. CORRECTION Perform idle-learn reset with a compatible scan tool. Verify commanded and actual idle speed.

CUSTOMER CONCERN Customer states the check-engine light is on. DTCs P0013 and P0014 are stored. CAUSE Resistance testing found the exhaust camshaft position actuator solenoid outside the specified 5–9 ohm range, confirming solenoid failure. CORRECTION Remove and replace exhaust camshaft position actuator solenoid. Clear DTCs and verify camshaft timing operation.

CUSTOMER CONCERN Customer states the malfunction indicator light is on, the engine surges at idle and raw fuel odor is present. DTC P0171 is stored. CAUSE Testing with the front oxygen sensor isolated confirmed an exhaust leak from a cracked exhaust manifold was altering fuel-control feedback. CORRECTION Remove and replace exhaust manifold. Repair exhaust leaks, clear DTC P0171 and verify stable idle operation.

CUSTOMER CONCERN Customer states the brake lights intermittently remain on. DTCs C0561 and C0161 are stored. CAUSE Brake-booster alignment caused incorrect brake-switch operation, confirming a misadjusted booster-to-cowl mounting position. CORRECTION Remove brake booster, install specified spacing washers on the booster studs and reinstall booster. Clear brake DTCs and verify brake-light operation.

CUSTOMER CONCERN Customer states the vehicle intermittently will not crank or start. DTC P0601 repeatedly returns. CAUSE PCM power and ground circuits tested correctly, confirming an internal memory fault in the Powertrain Control Module. CORRECTION Remove and replace Powertrain Control Module. Program module with current calibration, perform crankshaft-position variation relearn and clear DTC P0601.

CUSTOMER CONCERN Customer states the vehicle surges during acceleration and the drive belt chatters when the engine is revved. CAUSE Inspection confirmed a worn serpentine belt and worn belt tensioner that could not maintain correct belt control. CORRECTION Remove and replace serpentine belt and belt tensioner. Verify proper belt tracking and operation.
