Question about Lincoln Navigator

1 Answer

We have a 04 Navigator, we replaced several air ride height sensors and solenoids. We re-scaned and had the following C1991 and C1990 and it wouldn't take the re-programing. Ford suggested we replaced the VDM, same problem , air ride suspension light on. The air ride has worked excellently since replacement the height sensors, it seems like a programming problem only. However, now it has been suggested to replace the compressor. Please help

On a 2004 Lincoln Navigator the check air suspension light came on. there are no leaks on the lines but the car bounces on the smallest of bumps. Is there a relay or something that has gone bad?


There is a relay an there is a control module that controls everything in the air suspension system an ride height sensors an related wiring ! The control module can have diagnostic trouble codes stored in it's memory as to what the problem could be ! Here are some of the basics to check !
Inspection and Verification
  1. Verify the customer concern.
  1. NOTE: If the door ajar indicator is illuminated when all doors, liftgate, and liftgate glass are closed, the air suspension will not work correctly. Repair door ajar indicator; refer to Section 413-01 . Visually inspect for obvious signs of mechanical and electrical damage.

Constructive----I have a very complicate 2004 Linclon LS and relatives have the Navigator, and Expeditions,Etc.

These vehicles have so many issues, dealers are not an option, because of cost, and there inability to even find an issue,that fortunately, I have done my own repairs for 47 years and stayed up with the technology.

I would say unless you have a local shop and a few dollars left,to diagnose and repair that air ride system,which I don't see as a problem, I would recommend you replace the suspension with conventional parts ,such as strutmasters offers or other Mfg may have. That way eliminate the air suspension issues.
It is ten years old and you will have the rest of it's ownership ,making love ,to constant COP Ignition Coil problems and more,so you don't need to stay with suspension issues

You should no way be at a dealer, for any make or model vehicle ,after the warrantee runs out.
If you have deep pockets,want nothing repaired and as people have coined it,get ripped off (over charged) then a dealer will hook you up

The rear air ride wont go up. 02 navi.


There is a diagnostic plug for the Airride. You might find a scanner at Autozone or Oreillys. They will scan for free if they have a compatible plug.

You have done a good job in trying to track the problem. But the ride height sensors and the angle of your parking area can affect when the parts will work.

The door jam switches also put the Airride into sequence. You may have noticed how the car waits until everyone is out before deflating. So not hearing the airflow while you hear the rear solenoids "clicking"
may mean the door jam switches are preventing the pumping.

This is one of those things that a diagnostic tester can find. This is also why each door jam switch costs over $10 and have 3 wires instead of 1 grounding wire.

I have a 1994 lincoln continental car. Hoe do I replace the suspention drier?


why do you want to replace it? As air is exhausted through it, it dires it out for the next use. it's part of compressor assembly.

1996 cont'l The air suspension system includes the following major components:
  • Air compressor to supply air to the air springs (part of front spring and shock and rear spring and shock absorber assemblies
  • Front spring and shock (3C098) and rear spring and shock absorber (5A965) at each corner of the vehicle
  • Four linear air suspension height sensors (5359): two rear and two front height sensors to maintain the vehicle at the proper ride height; only LH rear height sensor is used for air suspension.
  • Dual-mode front spring and shock and rear shock absorber assemblies with internal actuator.
All system functions are controlled by vehicle dynamics control module (5A919). This control module receives inputs from several different sources. These inputs include:
  • vehicle speed via multiplex communication network
  • ignition switch position
  • door position via multiplex communication network
  • height sensor position
  • air suspension service switch
  • engine rpm via multiplex communication network
  • ride and steering personality settings via multiplex communications network
Communications monitor system operation and allow diagnosis of any concerns that may develop in the system. System monitoring for the driver's use is provided through the instrument panel mounted message center indicator (10D898).
  • Diagnosis communication for the service technician is provided through the data link connector (14489) (DLC) under the instrument panel and Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent.
The message center indicator will display AIR LEVELING DISABLED or CHECK RIDE CONTROL if the suspension system is not turned on or the vehicle dynamics control module detects a concern. If air leveling system disabled is displayed, check that air suspension service switch is in the ON position.
----------------------------------------------------------
Solenoid Valve Vent The vent solenoid valve operates as follows:
  • The vent solenoid valve allows air to escape from the system during venting corrections.
  • The valve is located in the air compressor cylinder head and shares a common electrical connector with the motor.
  • The valve is enclosed in the cylinder head casting, which forms an integral valve housing that allows the valve tip to enter the pressurized side of the system.
  • Air leakage past the valve tip is prevented by an O-ring seal.
  • The vent solenoid valve opens when a corner of the vehicle is high and the vehicle dynamics control module (5A919) determines lowering is required.
  • When the vent solenoid valve is opened, it provides an escape route for pressurized air.
  • However, the vehicle will not lower unless the air spring solenoid valves (5311) are also opened to allow air to leave the springs.
  • Lowering the vehicle corners requires the vehicle dynamics control module to open two solenoid valves, the vent and one air spring solenoid.
  • Air is exhausted from the spring and vents through the compressor air drier (5346).
---------------------------------------------------------------------------------------------
Section 04-05: Suspension, Computer Controlled 1996 Continental Workshop Manual
REMOVAL AND INSTALLATION Air Compressor and Drier Assembly Removal
  1. Turn air suspension service switch OFF.
  1. Disconnect electrical connector located on the air compressor.
  1. Disconnect two air lines from compressor air drier.
  1. Remove three fasteners retaining air compressor and drier assembly to radiator support, frame rail and fender apron.

What is the normal operation of the 04 navigator air suspension? i don't have a manual. should the vehicle drop when i stop and raise when i crank it...how's it work if all is good?


As a Past owner of several "air rides" that is how they work. Also when you put it into 4x4 on some models the vehicle will raise another 1-2 inches.

On any model with the air ride you need to remember that the height of the vehicle is usually higher after driving. This means after parking over a curb bumper or a sidewalk, the bottom will rub unless you give the car time to rise.

The system is more useful when hauling a trailer or carrying heavy loads as it will level the vehicle automatically.

REPLACED DRYER ON 96 CONT NOW THE BACK WONT AIR UP FRONT DOES


maybe you got dirt in the line to the rear. Here's some background info:

The air suspension system includes the following major components:
  • Air compressor to supply air to the air springs (part of front spring and shock and rear spring and shock absorber assemblies
  • Front spring and shock (3C098) and rear spring and shock absorber (5A965) at each corner of the vehicle
  • Four linear air suspension height sensors (5359): two rear and two front height sensors to maintain the vehicle at the proper ride height; only LH rear height sensor is used for air suspension.
  • Dual-mode front spring and shock and rear shock absorber assemblies with internal actuator.
All system functions are controlled by vehicle dynamics control module (5A919). This control module receives inputs from several different sources. These inputs include:
  • vehicle speed via multiplex communication network
  • ignition switch position
  • door position via multiplex communication network
  • height sensor position
  • air suspension service switch
  • engine rpm via multiplex communication network
  • ride and steering personality settings via multiplex communications network
Communications monitor system operation and allow diagnosis of any concerns that may develop in the system.
  • System monitoring for the driver's use is provided through the instrument panel mounted message center indicator (10D898).
  • Diagnosis communication for the service technician is provided through the data link connector (14489) (DLC) under the instrument panel and Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent.
The message center indicator will display AIR LEVELING DISABLED or CHECK RIDE CONTROL if the suspension system is not turned on or the vehicle dynamics control module detects a concern. If air leveling system disabled is displayed, check that air suspension service switch is in the ON position.
-------------------------------------------------------
Weight Added When weight is added to the vehicle, the air suspension system responds as follows:
  • Air suspension height sensor length is reduced from trim length, sending a "vehicle is low" signal to the vehicle dynamics control module (5A919).
  • To restore vehicle to the trim position, the vehicle dynamics control module turns the compressor on by grounding the compressor relay control Circuit 420 (DB/Y). The relay is ground-side switched.
  • To allow pressurized air to enter the rear spring (5560) and front spring and shock (3C098), the control module opens the solenoid valves (5311).
  • Compressed air flows from the compressor, through the compressor air drier assembly, air lines and solenoid valves into the air springs.
  • As the air springs raise the body height, the air suspension height sensor (5359) increases in length until the preset trim height is reached.
  • The vehicle dynamics control module then turns off the compressor (through the relay) and closes the air spring solenoid valves.
  • ----------------------------------------------------------------------------
  • Weight Removed When weight is removed, the air suspension system responds as follows:
    • Air suspension height sensor length is increased from the trim length, sending a "vehicle is high" signal to the control module (5A919).
    • To restore the vehicle to the trim position, the vehicle dynamics control module opens the vent solenoid valve (located in the compressor assembly) and opens the solenoid valves (5311).
    • Compressed air flows from air springs, through the solenoid valves, air lines, compressor air drier (5346) and out the vent solenoid valve.
    • As the body lowers, the air suspension height sensor length decreases until the preset trim height is reached.
    • The vehicle dynamics control module then closes the vent and solenoid valves.
------------------------------------------------------------------------------
Control Module Power and Ground The vehicle dynamics control module (5A919) is located above the upper luggage compartment trim panel and lower module tray. Module power is provided by Circuit 418 (DG/Y) at Pins 36, 37, 56, 57, 58 and is powered through a Fuse 7 (30A) in power distribution box. Module ground is provided through control module wire harness Pins 6, 39, 40 and 60. The data link connector (14489) (DLC) is located in the passenger compartment under the instrument panel, 300 mm (12 inches) right of the steering column. This connector allows communications between the vehicle dynamics control module and either Rotunda New Generation Star (NGS) Tester 007-00500 or equivalent or Rotunda Service Bay Diagnostics System (SBDS)® 001-00001 or equivalent. When the CHECK RIDE CONTROL message is displayed in the message center indicator (10D898), a system error has been detected by the vehicle dynamics control module and is stored in the control module. This diagnostic trouble code (DTC) will be retained for the next 80 ignition switch cycles. If there is no repeat of the same error during these 80 ignition switch cycles, the control module will erase the DTC. Because of this self-erasing memory, a customer may have had a concern "just a few days ago" that is not retrieved from memory when Diagnostic Test Mode (DTC) "Retrieve/Clear Continuous DTCs" is executed. This must be kept in mind if you must tell customer that no current concern has been found. When the vehicle dynamics control module detects a concern, the air suspension system is disabled for the current ignition cycle. If the condition causing the concern clears up during the current ignition switch cycle, the system will not reactivate. For example, if the customer has severely overloaded the luggage compartment, the system will not be able to trim the vehicle without exceeding the compressor run time. This will generate a DTC that disables the computer controlled suspension system. If the customer then drives the vehicle and unloads the luggage compartment without turning the ignition switch OFF, the system will not adjust for the new load. The customer will experience poor ride quality and the vehicle will not adjust trim.

Lincoln navigator air suspension is all the way down


that should not happen. Did you turn the switch off in the back for the suspension? Did you do something else at the same time, like check the spare tire for air pressure?

I have info on 2003 navigator 4 wheel air suspension. Maybe similar

SECTION 204-05: Vehicle Dynamic Suspension — 4-Wheel 2003 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Vehicle Dynamic Suspension The four wheel air suspension system is comprised of the following components:
  • service switch
  • control module
  • two front height sensors
  • one rear height sensor
  • compressor and drier assembly (includes vent solenoid)
  • air lines
  • front and rear air spring and shock absorber assemblies
  • four air spring solenoids
WARNING: The service switch for the air suspension system must be shut off prior to hoisting, jacking or towing an air suspension vehicle. This can be accomplished by turning off the air suspension switch located in the jack storage area in the rear of the passenger compartment. Failure to do so may result in unexpected inflation or deflation of the air springs which may result in shifting of the vehicle during these operations.

WARNING: Do not remove an air spring under any circumstances when there is pressure in the air spring. Do not remove any components supporting an air spring without either exhausting the air or providing support for the air spring to prevent vehicle damage or personal injury.

Item Part Number Description 1 5319 Air compressor and drier 2 5B322 Air line T-fitting 3 5B321 Air line union 4 — Air line Y-fitting 5 18945/5311 Air spring and solenoid
------------------------------
Principles of Operation
The 4-wheel air suspension (4WAS) module commands changes in vehicle height that are necessary for both the load leveling and the vertical height adjustment features.
The 4WAS load leveling feature automatically makes adjustments in vehicle height so that the vehicle is always at trim height, and that constant front-to-rear vehicle attitudes are maintained over the load range of the vehicle. Adjustments in height that are necessary to correct height differences between the vehicle left and right sides for the 4WAS system are restricted to what can be reliably achieved with three height sensors.
The height adjustment feature has three vehicle heights within a two-inch span:
Kneel height — improves the ease of entering and exiting by lowering the vehicle one inch below the trim height in the front and rear when the vehicle ignition is in the OFF or LOCK positions and the vehicle is stationary.
Trim height — normal vehicle ride position; vehicle moves to trim position when the ignition is ON, when the transmission is initially shifted to DRIVE or REVERSE mode, when all doors are closed or when speed of more than 24 km/h (15 mph) is detected.
Off-road height — improves ground clearance by raising the vehicle one inch above trim height in the front and rear when the vehicle is at 4x4 low modes and the vehicle speed is less than 40 km/h (25 mph).
The 4WAS module uses the universal bus protocol, (UBP), module communications network for sending and receiving various signals with the exception of speed, information from the three height sensors, and the air suspension service switch. For additional information about UBP, refer to Section 418-00 .
The 4WAS system holds vehicle height when any door or rear hatch is opened. The system stores front and rear vehicle height the moment any door is detected open. The system then maintains this height regardless of the addition or removal of a load. The system returns to its commanded height when all doors are closed or vehicle speed exceeds 24 km/h (15 mph).

-------------------------------
Air Suspension Service Switch
The air suspension service switch signal is needed to wake up the 4WAS module. Without the module receiving this signal, the 4WAS system is inoperative at speeds below 24 km/h (15 mph) and will not react when the vehicle is raised or lowered. At speeds above 24 km/h (15 mph), the system will be active as if the air suspension service switch is in the ON position.
Vehicles without message center When the air suspension service switch is in the OFF position and the ignition switch is in the RUN position, a "CHECK SUSP" will appear in the RH corner of the instrument cluster.
Vehicles with message center When the air suspension service switch is in the OFF position and the ignition switch is in the RUN position, the message center will display "SUSPENSION SWITCHED OFF"
-------------------------------------------
Inspection and Verification
  1. Verify the customer concern.
  1. NOTE: If the door ajar indicator is illuminated when all doors, liftgate, and liftgate glass are closed, the air suspension will not work correctly. Repair door ajar indicator; refer to Section 413-01 .
    Visually inspect for obvious signs of mechanical and electrical damage.
