Service ride control light on

SOURCE: engine will not start now

i had same problem the fuel pump is bad. it comes with a new sending unit also but dont buy the cheap one learned my lesson replaced it three times

SOURCE: Service Ride Control has come on

The vehicle needs to be put on a scanner and checked. This system is too complex to check once you have checked the fuses are replaced or OK. Do your best to make a friend at the dealership and see if a tech is willing to give it a quick scan. The trouble codes will then point you to the problem. Only a dealer scanner will work. With the trouble code / problem diagnosis (i.e.C0660 exhaust valve circuit malfunction) we can help further.

That is an indication that your air shocks at the rear needs to be replaced or there is a sensor that may have gone bad, event the air pump mey not be working. Most owners replace the more expensive air shocks with good conventional shocks like Monroe Reflex Shocks if there not towing heavy trailers. You can have the conventional shocks installed and have the ride control system deactivated. First check your fuse just t make sure the fuse to the air compressor has not gone bad, and the air ride leveling sensor, wire harness has not been damaged due to corrosion.
