What electrical device/s send this message(SERVICE 4WD) to the Instrument Panel. The Locking Rear Axle Button flashes sometimes as well.

Thank you for your reply.

Maybe I should be a little more specific. What electrical device/s initiate a "SERVICE 4WD" message to the Instrument Panel and would also cause the Locking Rear Axle Button to flash.

Thanks

In my experience, that message meant that the coil assembly retainer has failed. This means that the actuator wires have been broken due to the rotation of a component designed to remain stationary. This will require the replacement of the coil assembly because the wires ripped durring rotation. You will need to remove the e-locker, remove the bearing, and C clip in order to remove and replace the coil assembly. The coil will cost you around $150 bucks.

This will be covered under warranty.

The wire is connected to the coil.

The coil retainer is a 3/16 this hardened wire that fractures under pressure.

the pic shows the broken retainer.

Because this happened to me 3 times, I designed and custom manufactured a new retainer. I will have to post the specs some time.
