TECHNICAL SERVICE BULLETIN - 2021 Mustang Mach E and 2021 F150 - 29 July 2021
Various Driver Assistance Feature Concerns And/Or IPMA DTCs U3000:49, U3000:89, U2107:68, C1001:54 And/Or C1001:78


Issue: Some 2021 F-150 and Mustang Mach-E vehicles may exhibit various driver assistance system warning messages or inoperative features and/or diagnostic trouble codes (DTC) U3000:49, U3000:89, U2107:68, C1001:54 and/or C1001:78. This may be due to software in the image processing module A (IPMA). To correct the condition, follow the Service Procedure to reprogram the IPMA to the latest level.

Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria:

• 2021 F-150/Mustang Mach-E
• With or without one or more of the following DTCs in the IPMA:
- U3000:49
- U3000:89
- U2107:68
- C1001:54
- C1001:78

• At least one of the following concerns:
- Front Camera Fault Service Required message
- Pre-Collision Assist Not Available message
- Reverse Brake Assist Not Available message
- Lane-Keeping System Fault Service Required message
- Collision Warning Not Available message
- Check Front Park Aid message
- Check Rear Park Aid message
- Blind Spot System Fault message
- Adaptive cruise control inoperative
- Auto high beams inoperative
- Traffic sign recognition inoperative
- Front windshield camera alignment routine fails to complete

Warranty Status: Eligible under provisions of New Vehicle Limited Warranty (NVLW)/Service Part Warranty (SPW)/Special Service Part (SSP)/Extended Service Plan (ESP) coverage. Limits/policies/prior approvals are not altered by a TSB. NVLW/SPW/SSP/ESP coverage limits are determined by the identified causal part and verified using the OASIS part coverage tool.

Repair/Claim Coding

Causal Part:	14G647
Condition Code:	04

Service Procedure

1. Is only DTC U3000:49 present in the IPMA and does the vehicle also exhibit indications of a low battery voltage condition such as DTC U3003 present in other modules or an engine no crank/no start concern?

(1). Yes - this article does not apply. To clear the DTC, download and run the Reset the Image Processing Module A (IPMA) Learned Values application in Ford Diagnosis and Repair System (FDRS). Then run the Image Processing Module A (IPMA) Alignment application immediately after. The IPMA should not be replaced for this condition. Check for OASIS messages for low battery voltage and continue with diagnostics for low battery voltage.

(2). No - proceed to Step 2.

2. Is the DTC U2107:68 and/or DTC U3000:89 present, and only after performing an IPMA self-test?

(1). Yes - this article does not apply. Clear the DTC and only perform diagnostics for U2107:68 and/or U3000:89 if these DTCs set outside of an IPMA self-test.

(2). No - proceed to Step 3.

3. Reprogram the IPMA using the latest FDRS software level.

(1). IPMA programing could take up to 2.5 hours, however no technician interaction is needed during programming.

4. Perform the FDRS Image Processing Module A (IPMA) Alignment procedure.

5. Perform the appropriate FDRS camera alignment procedure.

(1). For vehicles equipped with 360 degree cameras, perform the IPMA - 360 Degree View Camera Alignment procedure.

(2). For all other vehicles, perform the IPMA - Pro Trailer Backup Assist Camera Alignment procedure. This procedure should be performed on all vehicles without 360 degree cameras, even if the vehicle is not equipped with pro trailer backup assist (PTBA).

END TSB
Attached is the PDF. It appears they finally have fixes for all of the intermittent issues with driver assistance features that many of us have seen.

I've had some of these error messages on rare occasions. Although I would classify this as something I can wait for an OTA to fix (assuming this is a module that can be reprogrammed OTA). Any idea if this is OTA-able?

 

[breeves002]

Yes it can be reprogrammed OTA. Ironically the update is actually significantly faster OTA (in theory) than the dealer can do it. The dealer is rate limited to 512kbps (HS-CAN via the OBD2 port) versus 1gbps from the OTA once it has downloaded from wifi to the GWM.

Who knows when they'll push updates for the IPMA though. The first in theory is supposed to be the blue cruise update. That would also solve these issues so it may be worth waiting a few months if you don't have many issues.

And this is why dealers need the ability to locally distribute OTAs (and other software) over a private Wi-Fi network at dealerships.

Recently I have been getting "Intelligent cruise control speed sign recognition not available"

Although it still reads the signs and updates the posted limit, it just doesn't adjust the speed. And of course when this happens, blue cruise won't engage

I wonder if this TSM still applies. Maybe one of the BC updates messed something up..
