Check the fuse first...

Checked that first and thought it was ok but after checking it again noticed it was knackered seems to be ok now wonder why its popped the fuse

After replacing fuse tls works but ive noticed when driveing its pumping up the suspension every 5 seconds or so i can hear it doing it. I thought this is probably the position sensor so i checked for error codes in sfa on diagnostic mode but theres no codes so i thought id calibrate it but i cannot find a calibration address to do this

From memory it’s SFA20. It should flash up ‘CAL’. Click hazard light switch on-off and it’ll go through the motions.
I’ve got a fleet of 20series and I find Its a common issue with Tls pumping up-down every few seconds. As far as I can tell it is trying to find it’s neutral position, but it keeps overshooting it, hence the up...down...up...etc
Ive had the TLS controllers re-flashed with new software from deeres. Some of them are now fixed but one or two still do it. I’ve given up worrying!

Does it go down as soon as you turn it off?

Now Then..
Does it immediately settle to the bottom once the engine is off??
It's often debris in the valve unit.. Difficult to clean out unfortunately..

No it stays up like say 2” off the rubber stops

Ok cheers will it harm the tractor pumping the suspension all the time? I thought if it was the position sensor id be getting a code but nothing

Check the fuse first...

Hi I've a 6630 premium and I think she has blew the fuse on the TLS. I can't identify it behind the seat. Is it in a relay maybe
