SOURCE: Service 4 wheel drive

The service 4 wheel drive light comes on because there's a problem. The biggest causes of this I've seen are a software glitch in the final drive control module which the dealer can fix by reprogramming and the other is usually the electric actuator on the front axle housing. The only light that comes on by a timer is the one that says, "perform service" in your overhead console or odometer.

SOURCE: had service 4 wheel drive light now their is

Hi Steward,

It's unlikely a relay is producing your symptoms.

The on the fly 4WD in the Cherokee is engaged inside the front axle. If for some reason it doesn't fully engage, it produces a clicking sound until it either fully engages or disengages.

If that clicking you are hearing gets more rapid as you increase speed, slows down when you do, then that's what it is.

A vacuum leak is the likely problem, easy to fix, difficult to find.
I have a Cherokee. I had the same problem. Start checking vacuum lines that lead under the engine to an actuator attached to the front axle.

Good luck,
Mike

SOURCE: 1999 chevy silverado service 4 wheel drive light

I had a similar problem with the Service 4 Wheel Drive light which came on intermittently then became more consistent in the message center display. It would go into 4 wheel drive if the message center did not display the Service 4 Wheel Drive message in the message center, but not when the message was displayed. I found the transfer case switch module in the dash was defective, and it has been working with no other problems for three years.

2001 Nissan PAthfinder 4-wheel drive malfunctioning'


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)
