TECHNICAL SERVICE BULLETIN
Various Driver Assistance System Warning Messages - DTCs C1001:31,
U3000:89, And/Or U3000:49 Stored In The IPMA
23-2146
12 May 2023
Model:
Ford
2021-2023 F-150
Issue: Some 2021-2023 F-150 vehicles may exhibit various driver assistance system warning messages or
inoperative features and/or diagnostic trouble code (DTC) U3000:49 stored in the image processing module A (IPMA)
that will not clear and not be stored in the vehicle's history. DTC C1001:31 and/or U3000:89 may be stored in the
IPMA, but may have recently been cleared and stored in the vehicle's history. This may be due to a connection issue
between the IPMA Camera and the IPMA. To correct the condition, perform the following service procedure to repair
the connection and reset the IPMA.
Action: Follow the Service Procedure to correct the condition on vehicles that meet all of the following criteria:
• 2021-2023 F-150
• IPMA has DTC C1001:31, U3000:89, and/or U3000:49 present
• At least one of the following concerns:
- Front Camera Fault Service Required message
- Pre-collision assist inoperative
- Adaptive cruise control inoperative
- Front windshield camera alignment routine fails to complete

Service Procedure
1. Is DTC C1001:31 and/or U3000:89 stored in the IPMA or were recently stored in the vehicle's 60-Day vehicle
health alert (VHA)/DTC History? The vehicle's 60-Day VHA/DTC History (if applicable) can be found in the
Professional Technician System (PTS) > Connected Vehicle > Connected Vehicle Home.
(1). Yes - inspect the coaxial cables between the IPMA and the IPMA Camera for loose connections. Perform a
wiggle test to check C900 and C9128 connectors for loose connections. If no loose connections are present,
proceed to Step 2. If loose connections are present, reconnect and proceed to Step 3.
(2). No - proceed to Step 21.
2. Start the vehicle and wait 30 seconds. Clear and retrieve the DTCs. Is C1001:31 and/or U3000:89 present in the
IPMA?
(1). Yes - proceed to Step 4.
(2). No - the issue is intermittent. Replace both sections of coaxial cable running from the IPMA Camera to the
IPMA following Steps 4-6 and Steps 8-18, then proceed to Step 19.
3. Start the vehicle and wait 30 seconds. Clear and retrieve the DTCs. Is C1001:31 and/or U3000:89 present in the
IPMA?
(1). Yes – proceed to Step 4.
(2). No – proceed to Step 21.
4. Replace the coaxial cable running from the IPMA camera to the A-pillar by overlaying the new coaxial cable next to
the existing coaxial cable and cutting off the existing coaxial cable connectors. To do so, begin by lowering the
headliner (Figure 1). Refer to Workshop Manual (WSM), Section 501-05, Interior Trim and Ornamentation,
Headliner - Lowering.

5. Overlay the replacement coaxial cable into the headliner behind the headliner harness and overlay the new
coaxial cable next to the existing coaxial cable. (Figures 2-6) Use 3M™ film tape (not zip ties) to overlay the cable
in the A-pillar, as using zip ties with sharp cuts near the side curtain airbag may impede the airbag’s performance
once installed. Small zip ties may be used in the headliner and near the IPMA camera.

NOTE: Do not kink or route the cable in such a way that it bends greater than 90 degrees over 30 mm (1.2 in).
Sharp bends could damage the cable. Press the 3M™ film tape firmly to the headliner to make sure the tape
adheres to the headliner.
6. Reattach headliner to the roof using the headliner magnets and install a new C9128 connector to the IPMA
camera and reconnect the headliner wiring harness C900 electrical connector in the A-Pillar. Refer to Figures 7-8.
Cut off the existing coaxial cable connectors to make sure the original cable is not used again.
