Flashing rear diff lock light
 

Hi

I had a problem with my rig hanging on the hard stops in the rear end.

After reading a lot of the posts here online I removed the compressor and put in the temp solution where you can air up using the air(outlet) in the rear of the truck.

So now the truck is running with "constant" airpressure.

Then I got the service 4wd message, to begin with I thought it was because I removed the compressor - but I don't anymore, something else is wrong.

I will try the advice I have read on how to cycle the encoder.

But today when driving home from work just aftre I started the truck something strange happend which I can't find an explanation for.

The rear diff lock light kept flashing on my instument cluster ??

This even happend even though I'm in normal 4hi, the light stoped after a few seconds and then did it again a few times on my way home.

I don't think the transfercase is locked, that I would be be able to fel and hear.

Anyone know what it means when the light is flashing

Regards
Rene

Well if you have not noticed any mechanical problems I would be willing to bet your TCCM (Transfer Case Control Module) is going bad. Its located under the drivers side of the Dash. It's a black box that is a little bit larger than a pack of cigs. I have no clue what it costs to replace this box but I am sure its not cheap. I would have someone put a tech2 on it and see what they find.

Check all the electronic conections on the T-case also. Good luck!!
