ABS/AdvanceTrac Errors After Brake Change (& Fix)

[SlightTremor]

Hey Everyone,

I recently upgraded the brakes on my '24 Tremor (18k miles) and wanted to share an issue I ran into in the event it helps save someone else time & headache.

Initially, I placed the vehicle into brake maintenance mode using Ford's gas pedal/parking brake button procedure, that went as expected

1. I proceeded with changing out the front brake hardware
2. I proceeded with changing out the rear brake hardware, no issues with depressing the rear pistons since it was in service mode
3. I attempted to disable brake service mode, but was greeted with the below dash errors:
   1. Check Brake System Message
   2. Check Engine Light
   3. Service AdvanceTrac Message
   4. ABS Warning Light
   5. ACC Warning Message
4. I attempted disconnecting the battery for an hour, disconnecting/reconnecting the parking brake connectors, cycling the parking brake, but no luck
5. I attempted driving the Maverick, but the brakes were barely working with a very stiff pedal and when the pedal was pushed hard enough it was almost like the electronic parking brake was assisting and it braked really hard
6. I ordered a USB to OBDII adapter to use with Forscan overnighted through Amazon (Amazon Link)
7. Got Forscan setup/connected and did the following:
   1. Checked for codes, the below appeared:

      1. ===GSM DTC None===
         Successful DTC reading, no error codes found
         
         Module: Gear Shift Module

         ===END IPC DTC None===
         
         ===GWM DTC None===
         Successful DTC reading, no error codes found
         
         Module: Gateway Module A
         
         ===END GWM DTC None===
         
         ===IPMA DTC U0418:86-AF===
         Code: U0418 - Invalid Data Received from Brake System Control Module 'A'

         -ECU_INTERNAL_TEMPERATURE: 28 °C - ECU Internal Temperature
         ===END IPMA DTC U0418:86-AF===

   2. Ran the "Enter Electric Parking Brake Maintenance Mode" and then "Exit Electric Parking Brake Maintenance Mode" service procedures (example below is from this post):
      1. 
   3. Cleared any of the codes and cycled accessory power
8. Like magic, all of the dash warnings/lights went away and I was able to successfully perform the brake break-in/bed-in procedure

Based on the error codes received, my guess is that something went wrong when trying to disable/exit brake maintenance mode which left my Maverick in a bad state. Thankfully, Forscan saved the day and I didn't have to go to the dealer to have some kind of FDRS procedure performed.

The brakes I upgraded to are Powerstop Z17 (pads & rotars) that I had gotten with a substantial rebate. I had some brake noise when going into gear on the factory brakes and these resolved it.

The Ford Mav "brake maintenance mode" seems very wonky. I bought a Launch Creader for Ford OBD reader and used it for brake maintenance. Went into brake service mode fine but failed when trying to exit. I used the ignition/gas/e brake mojo to exit but had to try a couple of times before it worked. Did get codes similar to yours. Cleared them and all was good. Whoo!!
Glad to hear that Forscan is another option.
I do like the Power Stop brake kits. Good quality at a good price. If I'm not changing rotors I usually just buy OEM pads but if I'm changing rotors I'll buy the Power Stop kits.

Hey just had this happen to me.
Went to brake maintenance mode, replaced my rear pads, tried to go back now I have all kinds of brake service messages (22XLT). Is Forscan my best option to clear codes?

Just wanted to say thank you for this thread. I replaced all 4 pads and rotors on my 2022 Ford Maverick and immediately got ABS / AdvanceTrac errors afterward. The truck was barely driveable and I was honestly pretty stressed.

After reading this thread, I purchased an OBDLink EX adapter, connected FORScan, and cleared the codes. Everything went back to normal and the brakes now work better than ever.

This post saved me a ton of time and frustration. Hopefully this reply helps the next person too. Thanks again.

Happy this helped! When it happened to me, I was almost certain that I was going to have to get it towed to Ford. FORscan saved the day.
