ELC fuse? Do I need it?

[Larry]

I was setting the timing on my TY tonight, after I was done I crawled under the dash to pull the ECMB fuse to clear the code that was set from disconnecting the tan wire. I noticed the very bottom fuse listed as "ELC" was not there. I checked the manual and it listed it as a 20 amp fuse for ELC but does not explain what it's function is. I have had this truck for about 6 months now and I guess it has never been in there. I am guessing it is for the level control in the rear? Am I right or is it something else. Thanks guys, Larry.

Yeah it is the electronic levelling control.

Look under the drivers side rear fender and see if the pump is still there.
If it is pop in a fuse and see if it kicks on.

Lots of folks switch to preformance rear shocks and disable the pump.
I removed mine all together, it is dead weight at best.

Thanks for answering, I popped in a fuse and sure enough, it works. I guess the previous owner got sick of it and pulled the fuse. I am not sure if I like it either. But now I know. Thanks again, Larry Jones.

Part of the reason a lot of folks would disable it was the lines leaking.
If your pump just runs constantly then there is a leak somewhere.

Also it tends to lift the rear higher than shocks alone.
To adjust the height there is a sensor on the rear diff that needs tweaking.

Also if you lower the truck with springs or block the the sensor will need to be adjusted to take this into account.
I like the idea of the system especially if you have lowered the truck and then load it up with 4 fat boys and some gear. Some of the lowered trucks with regular shocks might have very limited suspension travel in this condition.
