Confirmed the customer's complaint and found the engine stalled when driving. Performed an underhood inspection and found the drive belt was glazed. Inspected the battery and the battery cables and found no faults. Used a multi-meter to measure the voltage across the battery terminals and found the measured voltage was below the specified range. Used a battery conductance tester to test the battery and found the battery was able to conduct the specified amount of current, which verified it operated properly. Performed a visual inspection of the alternator and found no obvious faults. Used an alternator load tester to test the alternator by placing the battery under load, raised the engine speed to 1,500 RPM, and found the measured alternator output was below the specified minimum amperage. Off idle, used a lab scope to measure the AC ripple in the charging system by connecting the lab scope leads across the battery terminals. The AC ripple observed on the lab scope was above specifications. These test results verified the alternator and the drive belt were faulty.
MAKE SURE ALL WIRES ARE INSERTED INTO PROPER CAVITIES. RE-ASSEMBLE BACK TOGETHER. CONNECT BATTERY. MAKE SURE ALL OTHER WIRES ARE HARNESSED PROPERLY. TEST ALL AFFECTED SYSTEM.

Connected a scan tool and found codes: P0301 – Cylinder 1 Misfire Detected and P0302 – Cylinder 2 Misfire Detected. Confirmed an engine misfire was present when the engine was first started. Connected a spark tester to ignition coil #1 and ignition coil #2, checked for ignition spark at both coils while the engine cranked, and found no spark on ignition coil #2. Performed a visual inspection of ignition coil #2, related wiring, and connector terminals but found no obvious faults. Swapped ignition coil #2 to a different cylinder, ran the engine, and monitored the misfire data on the scan tool. The misfire followed the ignition coil, which indicated ignition coil #2 was defective. Removed the spark plugs for inspection and found the spark plugs were excessively worn, which indicated the spark plugs needed replacement. REMOVE ALL NECESSARY COMPONENTS. REMOVE AND REPLACE ALL SPARK PLUGS AND TWO IGNITION COILS. ASSEMBLE TOGETHER AND MAKE ALL NECESSARY ADJUSTMENTS.

Observed the engine coolant temperature gauge and found the engine coolant temperature exceeded the allowable specifications. Connected a scan tool and found code P0480 – Fan 1 Control Circuit. Inspected the engine coolant level and found it eas at the proper level. Key on, used the scan tool to command the engine cooling fan relay on and observed the relay made an audible click, but the engine cooling fan did not function. Performed a visual inspection of the fuses and relays, but found no concerns. Inspected the engine cooling fan wiring harness and found no evidence of any damage. Disconnected the engine cooling fan harness connector, visually inspected the connector and found no apparent concerns. With the engine cooling fan harness connector disconnected, rotated the engine cooling fan by hand and found it freely rotated. Connected a multi-meter to the engine cooling fan harness connector to test for voltage and ground while the scan tool was used to command the engine cooling fan on. Found both voltage and ground were present. Attached fused jumper wires across the engine cooling fan terminals, applied voltage and ground and found the engine cooling fan did not operate. The results of these tests verified the engine cooling fan was faulty.
