Recall? ?

Recall? ?

There's a limited recall of the electric brake booster/abs module on 51 vehicles produced between dec 20 and jan 21. My local dealer says there are 282 on backorder already but Fords yet to acknowlege any other issues with this braking system. You can't even buy a used one because it's a vin locked part and part of the PATS system.

Look for a remanufactured one as thses are selling for around $100. A local shop can provide a quote on cost to install in your truck.

Looking at the workshop manual, I don't see any reason why you couldn't install a used ABS module and program it to your truck, but this may be beyond the scope of what a dealer is willing to do for liability reasons. I wouldn't really want to install a used EBB assembly either, but there are plenty for sale on eBay if someone really wanted to take that risk.

Generally speaking, every backordered part that I've ordered from Ford has shown up in less than one week, so I wouldn't get too worried about the timeline just yet. If your dealer places their orders correctly and has a good relationship with Ford, their orders should get filled fairly quickly. Ford seems to use just-in-time inventory management for a lot of parts, so lots of stuff goes on backorder periodically and it usually doesn't indicate a long lasting delay.

But any shop with familiar FDRS should be able to install and program a new unit? There's a couple of nos ones on ebay in the $500 range and lakeland is showing new ones for $800....Much better than the $1300 my local dealer quoted.

Because the ABS module is part of the PATS system, I think you will need to find a shop that has FDRS and a NASTF SDRM credential (locksmith license for vehicle immobilizer programming).

That being said, sometimes programming a used module with FDRS requires a little extra trickery that many shops won't be familiar with.

The most common scenarios are to not plug the used module in right away or to not plug the J2534 into the truck right away so that the programming or module identification fails. The goal in doing this is to keep FDRS from seeing the used or incompatible module until it starts trying to force write the as-built data to it in an attempt to recover the module. It's really simple and low effort, but not everyone knows to do it.

Yeah I was thinking of just ordering a new one instead of a used one. Just stinks I'm an industrial tech by trade and would be comfortable with the install myself...Just no access to the computer system.

Getting FDRS isn't bad, but getting a NASTF SDRM credential isnt an option for most people or most mechanics. The $1,000,000 commercial liability insurance requirement is the worst part. Getting fingerprinted, having a background check run on you, and paying $325 every 2 years for a NASTF SDRM credential isn't horrible, but as an individual the insurance expense is completely unjustifiable unless you are a full time automotive locksmith.

Seriously?
What does ABS have to do with truck ignition? ?

According to the service manual:

PATS

The PATS function is controlled by the BCM , the PCM , ABS , and SOBDMC (if equipped).

When the START/STOP button is pressed, a voltage signal is sent to the BCM . When the BCM detects the START/STOP button is pressed, it begins the key initialization sequence by activating the PATS center antenna and keyless entry rear antenna. Each antenna transmits a low frequency signal with an approximate range of 1m (3ft). The passive key activates if it is within range of the antennas. The BCM is able to determine the passive key location (inside or outside the vehicle) based on the input from the antennas.

When the passive key activates, it sends the PATS identification code to the RTM via a high frequency signal. The RTM interprets the high frequency signal from the passive key and sends the information to the BCM over the LIN based circuit.

If a programmed passive key is detected inside the vehicle, the BCM transitions the ignition from OFF to ON.

When the ignition transitions from OFF to ON and the modules initialize, the PCM sends a target 1 challenge request, the SOBDMC sends a target 2 challenge request (if equipped), and the ABS module replies to a target 1 challenge request to the PCM . The BCM replies and if the correct identification is received, the PATS disables and allows the vehicle to start. If the PATS prevents the vehicle from starting, a DTC sets in one of the modules.

The PATS and the RKE system share operation of several components including the passive keys, the BCM , and the RTM .

If there is a concern with either of these components, the PATS and the RKE system are both affected.

In the event of a no start, place a programmed passive key in the backup location to allow the vehicle to start. The PATS center antenna activates the passive key when the START/STOP button is pressed in the event the batteries are depleted within the passive key.

NOTE: If available as a selection on the diagnostic scan tool, the passive start feature is a programmable parameter and can be enabled/disabled. If the feature is disabled, the features to passively enter and start the vehicle are inoperative. To start the vehicle, the passive key must be placed in the backup starting location.

The BCM controls the ignition modes and in conjunction with the PCM , ABS , and the SOBDMC (if equipped), controls the PATS .

So was able to use a friends scan tool today instead of forscan and received 3 other codes I couldn't see. Looks like theres a TSB for the U0415...Any suggestions Saleen? The truck also has 3 open recalls...Do I just show them this report when I take truck in for those and ask them to update the Software?

Good morning. I would like to take a closer look at your ABS concerns on my end. Can you please send over a message with your VIN and estimated mileage to get things started?
