Fault is inact suspension light plus very hard to get it to off road height pump goes forever and doesn't get there
4.8 is 2005 and done the air bags, pump relay, overhauled pump and that improved it so thought I was on the right track, fitted new pump and its the same although the light hasn't come on yet. I thought the reservoir tanks were supposed to hold enough air to raise vehicle once without using pump. Original code was 74 accumulator requesting filling.
One last observation , are the rear ride height sensors supposed to be at an angle as the front ones are dead level.
Any help would be appreciated as it is driving me nuts!!
