I did some asking around in this thread- https://www.ford-trucks.com/forums/1...eration-q.html if it helps any it is more background and verification about PATS.

The last post has some additional info on the module. I don't think the cluster is PATS connected. The PATS modules just sends a signal and the cluster displays the info.

As for the odometer- don't know. Did the gauge remain in the truck? I need to take mine out to replace the bulbs so any insight you share is appreciated.

 

If you have the cluster, ECM and pats key(s) from a donor you should be good to go, but what's the chance of getting all that from one junker?

 

i dont understand how pats is talking to the cluster, anyone have a schematic that shows wires pats is using for the clusteR?

 

To avoid having the dealer doing any reprogramming I believe you will need all 3 parts because of the speedometer. I don't have any first hand knowlege there, just reasoning.

 

Pats has nothing to do with the cluster except for the warning light. You have the transceiver at the ignition switch which reads the key. Sends the signal to the Pats module which then sends a signal to the PCM to allow starting the truck. There's also one 10A and two 5A fuses for the Pats but other than that nothing else.

 

so is it possable to drive then with a different cluster or no cluter attached at all?

 

I think these clusters are rigged so that you can't just change them out that easily and expect the odometer to work properly. Otherwise, people with high mileage vehicles would just get a cluster with lower miles, replace the old high miles cluster, and sell it as though it has low mileage. Something used car dealerships as well as private sellers would love to be able to do.

 

funny how i removed the light for the seatbelt and used it in the door ajar hole, now i get a softcode of seatbelt circuit falure or something like that! hehe crazy computers. thats in my 00 excursion, guess i gotta go to dealer to get me that light socket.

 

From what I recall the mileage is stored in the PCM, not the cluster. Not too sure about the earlier models.

I think thats because the bulb filament forms part of the ground circuit and by removing the bulb you have an open circuit.

 

The 2000 and 2001 models have the mechanical odometer. My 02 has digital.

 

can you put the digital odo cluster in the mechanical odometer truck and have it work?

 

The mileage stays with the cluster and they can be changed but the replacement cluster must be from the same exact year in most cases.

 

do you think this is the millage chip for the cluster or the pats plugin chip?

 

Looks as though that circuit takes care of something simple like oil/temp/volt gauges or lighting.

The odometer circuits are normally right on the speedo itself and has an actual microchip like you would see in a computer or cell phone.

 

I think the best thing to do is not mess with it. If you are trying to change your odometer from mechanical to digital or the other way around there is a lot more to it than meets the eye.

Principles of Operation
Some modules must be programmed as part of the repair procedure. If this procedure is not followed the module will not function correctly and may set a number of DTCs, including B2477 or P1639, which indicate that some necessary data has not been programmed into the module.
Modules that need programming should not be exchanged between vehicles. In most cases the parameter values or settings are unique to that vehicle, and if not set correctly will cause concerns or faults.
Some programmable parameters, such as belt minder on/off, can be changed from the factory setting at the customer's request.
WDS will automatically attempt to retrieve the module configuration information from all modules, and from a backup location in the powertrain control module (PCM) when vehicle ID is carried out. If the module and the PCM do not contain correct information the diagnostic tool will either request "As Built" data or display a list of items that you will need to manually configure. The diagnostic tool will program the module based on the data you enter.
There are three different methods that are used for module programming:

• programmable module installation (PMI)
• calibration update
• programmable parameters

Some modules do not support all three methods.
Programmable Module Installation (PMI)

The programmable module installation (PMI) method is used when a new programmable module is installed on the vehicle. It is no longer necessary to command the diagnostic tool to gather module option content from the old module. The diagnostic tool automatically obtains any available module option content information from the old module during the vehicle ID routine that runs when the diagnostic tool is initially connected to the vehicle. It is important that you connect WDS to the vehicle and allow it to identify the vehicle and obtain configuration data prior to removing any modules.
Calibration Update

Calibration update is used to install a new calibration and strategy into a module. The updates are usually issued to fix a concern in the module software and would normally be addressed by a technical service bulletin (TSB). This method has been used by the PCM for several years. Other modules will be adopting this strategy as well.
Programmable Parameters

This method is used to configure parameters that can be modified in service. These are typically at the preference of the customer. Not all features controlled by the module are listed in this configuration method. Refer to the Module Configuration Index for a list of features by system.
If a module that has been modified using programmable parameters needs to be installed, the PMI procedure will maintain the parameters in their altered state if WDS is able to communicate with the old module during vehicle ID. Otherwise you may need to use programmable parameters to return them to the altered state.
Vehicle Identification (VID) Block

Some PCMs contain a memory area called a vehicle identification (VID) block. The VID block is used to store backup data for each programmable module, as well as, powertrain configuration information.
If the diagnostic tool cannot retrieve module option content information from the suspect module, the diagnostic tool will attempt to extract backup information from the PCM's VID block.
The PCM VID block contains the factory settings for the configurable modules unless the PCM is flashed with a new calibration, in which case some PCM parameters may be modified.
As-Built Data Center

The As-Built Data Center maintains a record of the vehicle configuration in a database. The vehicle's VIN is required to obtain this information. The As-Built Data Center records the applicable module configurations stored in each module before the vehicle leaves the factory. The As-Built Data Center will always reflect the original build of the vehicle as it left the factory. Only contact the As-Built Data Center when directed to do so by the diagnostic tool.

Inspection and Verification

1. Visually inspect for obvious signs of electrical damage. Refer to the following chart:
