Troubleshooting Your 4WD System
Before you begin panicking, thoroughly understand the problem at hand.

Checking your Jeep’s manual will prove helpful in understanding the possible causes, but let’s dive into some specifics.

General Steps to Correct the Problem

When faced with the “4WD System Unavailable – Service Required” message in your Jeep, here is a checklist of things you can do:

2. Inspect the skid plates: If they are damaged, they could be affecting the system’s operation.

3. Check battery voltage: If the battery voltage is low, it might trigger a fault in the 4WD system.

4. Check fluid levels: Ensure the power steering fluid, engine oil, transmission fluid, and differential oil are all at the recommended levels.

5. Inspect tires: Make sure all tires are same size and inflated to proper pressure.

6. Consult your Jeep’s manual: Refer to it for specific information about the 4WD system.

If All Else Fails, Seek Professional Help

In some instances, you may have checked everything you can, but the “4WD System Unavailable – Service Required” warning persists. At this point, it’s time to consult with a professional mechanic.
