i have a 2001 suburban 1500 4x4 with autoride. problem is service ride control message is on all the time. the system seems to working fine. it will level out when started , it will level out when i put weight in back. the pump seems to be working ok and it seems to turn on and off as the height at the back of suburban changes. i dont have the real high dollar scan to check that part of system. hope to from some with some pointers.
thanks hunterjo

 

Get a free scan at most autoparts stores and that may shed some lite if there are any DTCs set.

 

the auto parts stores told me their scaner will not get any DTC,s that are set for that problem.

 

i have one more question it has to do with the positioning senors on each wheel. is there a way to check them without a scan tool. is there a ohm,s reading i can take or some other reading.

 

Can't answer that one. While it probably is a potentiometer, I don't have a clue as to what a nominal value should be.

Unless someone else here has some ideas, probably have to take it to the dealer.

 

I would think that if you inspected each sensor (4) the odd one out would be the bad one.

 

that is my same thought. i will give that a try and i will let ya know the results. it might be a couple of days before i can get to it.

 

i solved the problem. first i took ohms readings on each sensor. i got between 400-600 ohm readings on all but one.( the different readings was because i was reading between the three different wires) the forth one had a open reading. i could not find a used one anywhere so i ordered a new one. installed it and problem gone. hope this info will help someone else.

Also does it void any warranties?
