Front Air Springs Are Completely High and/or Rear Air Springs Are Completely Low. CHECK AIR RIDE Displayed 45 to 90 Seconds After Starting Vehicle. One Front Corner Is Completely Low. CHECK AIR RIDE Displayed 45 to 90 Seconds After Starting Vehicle. Rear Air Springs Are Completely Low. CHECK AIR RIDE Displayed 45 to 90 Seconds After Starting Vehicle
- Air suspension height sensor is off ball stud.
- Air suspension height sensor ground is open on corners that are not trim. Air suspension control module does not detect this as an electrical error.
- Wiring harness has intermittent open circuit.
- EXAMINE air suspension height sensor and REINSTALL on ball stud if required.
- RUN Function Test 211 to RETRIEVE stored DTCs.
- RUN Auto Test.
- DIAGNOSE/REPAIR Auto Test DTCs.
- If DTC 99 is received from either air suspension control module memory or Auto Test, GO to Pinpoint Test V and CHECK for open air suspension height sensor ground.
- RUN Function Test 223, 224 or 225 to test for intermittent air suspension height sensor and wiring concern.
if you look at the chart above, (this coms straight from a ford manual) acording th the symptoms given, if the sensors are correctly instlaled, then the problem is electrical
double chec fuses 28, in the instrument panel fuse panel and fuse 4 and 13 in the engine compartment fuse panel
at the air suspension/steering module, pin 10 (bk/pk) wire is common to all 3 height sensors
pin 28 (pk/w)wire is common to all 3 sensors
pin 7(pk/bk) is for l/f sneso
pin8(t) is for the r/f sensor
pni 9 is for the rear sensor
uplug the suspension module and all sensors check each circuit for opens, groudns and shorts
if the circuits are good and the sensors are instlled properly then all that is left is the module
let me know if you need any more info
let me know what you find, let me know how we did, positive feedback is greatly aprciated
