A four-wheel-drive light can have different meanings. A steady indicator may simply confirm the selected mode, while a flashing light may indicate a shift in progress or an engagement problem. A service warning can signal a detected fault.
Check your vehicle's manual for the specific symbol or message. An indicator alone cannot identify which component needs repair.
If a light continues flashing after the proper shift procedure, or a service message remains, contact Certified Transmission in Council Bluffs, IA. Mention any accompanying noise, binding, or change in how the vehicle drives.
