2008 Edge ABS Module Replacement

[Cleos0914]

I have a 2008 Edge, and recently had the brakes and rotors replaced. They told me at the time, that my ABS Pump and Brake Booster were also having issues. I was experiencing a lot of resistance when pushing down on the brakes, and it was slow to stop, but the ABS light never came on, so I was surprised that there was a problem with my ABS. The mechanic that replaced the pads and rotors, told me that I had to take it to the dealership and have the ABS module replaced. My questions are:

1) Does it have to go to the dealership to be fixed? They quoted me roughly $2000 for the parts and service, which frankly is just not worth it.

2) What do they mean when they say it has to be reprogrammed?

3) Are their other options for repair?

 

I hope I have phrased this correctly, and that i makes sense. If not, let me know. Any and all advice is welcome!

 

Thank you!

The ABS controller is a programmable module. So you have to start the Programmable Module Installation using the Ford IDS software, replace the module, then complete the installation with the new module in place. Maybe pro-level scan software/devices such as those from SnapOn can also do this, but IDK.

 

A description of the basic process for various such modules:

 

Principles of Operation

Configurable modules accommodate a variety of vehicle options, eliminating the need for many unique modules for one vehicle line. These modules must be configured when replaced as part of a repair procedure. Configurable modules should not be exchanged between vehicles since the settings are unique to each vehicle. Failure to configure a new module may result in incorrect operation and/or DTCs setting.

The following are the 3 different methods of configuration:

• Programmable Module Installation (PMI)
• Module reprogramming ("flashing")
• Programmable parameters

Some modules do not support all 3 methods.

Definition of Terms

The following are definitions of configuration terms:

Programmable Module Installation (PMI)

PMI is a scan tool process which configures settings in a new module. Data used for the PMI process is automatically downloaded from the original module and stored when a scan tool session is started. If this data cannot be retrieved from the module being replaced, the scan tool may prompt for As-Built data entry or display a list of parameter values that need to be manually selected. Some modules are reprogrammed during PMI when a strategy/calibration update is available. To carry out PMI , refer to Programmable Module Installation (PMI) in this section.

NOTE: It is important that the scan tool identifies the vehicle and obtains configuration data prior to removing any modules. The new module must be able to communicate with the scan tool in order to carry out PMI .

Module Reprogramming

Module reprogramming (also referred to as "flashing") is a scan tool process which updates the strategy/calibration in a module. Reprogramming a module with the same level of software does not improve module operation or repair a hardware failure. Module reprogramming is automatically carried out during PMI when a later strategy/calibration is available.

NOTE: Limit module reprogramming to circumstances where a published TSB procedure recommends doing so. (Some modules limit the number of times it can be reprogrammed.)

NOTE: A module cannot communicate with other modules on the communication network while being reprogrammed. After the reprogramming process, clear any network communication DTCs which may have been set in other modules.

NOTE: Some modules are reprogrammed in coordination with other modules. Follow the Integrated Diagnostic System (IDS) key cycling instructions carefully to avoid reprogramming errors, including failure of programming one or more of the modules.

There might be air trapped in the ABS controller/HCU. There is a separate procedure for getting that resolved, but I would check for air in the system first. Also inspect the booster/master cylinder closely to make sure there is no fluid leaking into the booster from the MC. Sometimes the vacuum hose is not attached properly or is breaking down. If the check valve on the booster is not working that could also be causing the issues.

 

Was/is the brake fluid completely clean? Dirty brake fluid should be flushed immediately.

 

You will likely end up replacing the controller and or the HCU though.

I'm having the same issue. I had the brake booster replaced last Friday (impossible to push the brake pedal to stop the car) by my local mechanic since the dealership couldn't get the car in for over two weeks. While they had it, I asked them to check why the ABS, anti-skid icon, and orange wrench were on (have been for 3 months) to see if they could fix it. They said they couldn't but didn't elaborate because I picked it up after hours.

 

Is this a $2,000 job?

Bleeding the ABS? No, pretty simple, I believe for some MYs, you can even do it with Forscan for Windows EL.
