Service 4WD Message and Check Engine Light Both On
What the customer reported
The vehicle owner reported that the check engine or service engine light was on and that Svc 4WD was on.
What we found and did
The technician at our Haines City shop started with a diagnosis of the engine concern, including testing and inspection of the vehicle system involved. The repair then included a dtcm module from dealer stock. The technician also ran the module programming and re-learn so the new part was set up for the vehicle.
