Town Car Air Suspension
Permalink  
 


I havent updated the software to the x431 yet because the owner of the shop hasnt registered it yet but was wondering if there is a feature to inflate and deflate the air suspension on a 2004 Lincoln Town Car.

i  worked on a  town car a few months ago ..i don't remember seeing  the option to activate the compressor .......maybe has been added to new software versions ..


do you suspect a leak in the  air suspension ?
if so...
you could always  apply power to compressor just to get air into the rear struts  to check for leaks .....or put some weight in the trunk with car on the ground and wait a few minutes for  system to react on its own crawl under and listen

The air springs were replaced along with the solenoids. I applied direct power to the compressor and it barely inflated them. According to ALLDATA a scanner with that function is needed to properly inflate the springs when they are replaced.

put car on 4 low jack stands under  frame  ......remove the level  switch arm ..i think it is a ball crank  and pops off  easily ... stay under the car so you can see what's going on 

trick the car into thinking it's rear bumper is on the ground by moving the arm  up  and let the  compressor fill the system ... remember to turn on the switch in the trunk... second tech controls the key and you control the  level arm .....reconect the level  arm  up when you get sufficient air in the  springs  

the original compressor may be shot from working so hard for who knows how long to fill   a leaky system
