How Do I Disable Air Suspension Light

It should be the GREEN wire that is midway in the plug to the right, where a YELLOW wire is on the right and two EMPTY spaces to the left. This is the wire I cut. Give yourself plenty of room to splice it back if needed.

Well it took me all week to figure out how to pull the plug out! I finally got it, unplug and no more Check air suspension light...Yea

Now that it is unplugged, cut the GREEN wire and plug it back in. The plug does more than just illuminate the Check Air Suspension light. If you have Speed Sensitive Steering, you're just disabled it too by unplugging that connection.

Already done...pulled the red center piece out, the pulled the green wire out of the back of the plug. re-connected the plug and bingo the light is out and the steer control is unscathed...

However all has gone bad this morning...not with the light but with the passenger-side mirror. I was backing out of the garage, not paying attention, when I herd the scraping sound of the mirror being pulled of by the trim that surrounds the door opening. I was able to screw it back on with large screws though...Now this is going to be costly, trying to find a new mirror...Not at all happy with myself.

D'oh!

I have confirmed with a Federal Mogul technical specialist that their instructions with the coil conversion kit are NOT correct for 1998 Lincoln Town Cars and later models. Because the air suspension system is now linked with the Electronic Variable Orifice Power Steering and data is sent from the Air Suspension/EVO Steering Module over the Multiplex Communication Network there is now NO WAY to shut off the air suspension warning message after converting from rear air springs to coil springs. He assured me that the coils work well after the conversion, but one has to be willing to live with the warning message. He also told me that they have requested the coil manufacturer (Moog) to correct their instruction sheet to reflect this reality on the newer models, but so far they have chosen to continue with the old instruction sheet.

Remove the on off switch in the trunk, cut both or remove the wires from the switch, bare each wire and tape them together. No more warning light.

Cutting the wires to and from the air suspension switch and removing it sounds like an easy fix. Unfortunately, a quick examination of the electrical diagram for the air suspension system of the 1998 Lincoln Town Car shows that the switch merely opens that particular circuit, so turning the switch off does precisely the same thing as removing the switch from the circuit.

As I stated in a previous comment, the technical specialist at Federal Mogul assured be that while the Moog CC865 coils they manufacture will very adequately replace the air springs of the Lincoln Town Cars from 1989 onward, they have found NO WAY to turn off the air suspension warning message on newer models beginning with 1998 because those models use the multiplex communication network to communicate with the instrument panel. (According to the electrical diagram, that panel communicates various important data, such as vehicle speed, driver's door ajar status, passenger's door ajar status, and odometer.) The technical specialist told me that their company had contacted the car manufacturer with the request that they revert to the previous configuration, but no change was forthcoming.

The bottom line--conversion from air springs to coil springs will definitely work but, for models beginning with 1998 and newer, the warning message will remain on.

We just replaced the suspension on my dad's 1995 Lincoln Town Car, and the instructions for disabling the Air Suspension Warning Light were not very clear. When I looked on this forum, I didn't find anything conclusive.

As a matter of fact, on his car, the connector had two white plugs on them - not a black and a grey. We first tried disconnecting the grey connector just to see if the light still came on, and it did. Plus, the black connector did not have the green wire with a light green stripe, but the white connector did.

So, we tried the white connector and that was correct. So I plugged it back in, and clipped the green / lt green wire and taped the ends. All is working. I'm going to (try to) post a photo or two as well.

Here's a photo showing the location of the module.

Here's a photo showing the green / lt green wire cut.

On my 1996, one of those plugs was a light grey color. Good job on deducing which green wire to cut.

so when you guys switched to springs did you do your shocks also im just wondering because my compressor took a shit the other day and dont have the money to replace it

When I installed the Coil Springs on my '96 Cartier, I did not replace the Shocks as they were still in good condition. Never did notice a change in the ride quality either - still as smooth as could be.

ok i was just wondering because it like 50 bucks more for the shocks two but yet mine might need it 1992 towncar

On my 95 I took out the glovebox and pulled the pin for the green wire out of the connector and it shut off the check suspension light
I love the ride with the coil springs
It rides every bit as goo as my 61 Buick
And for me the 61 Buick was the gold standard for how a car should float down the highway
