C1114 on 2022-2026 Ford E-Transit: ABS Module Power Circuit Fault

What's Unique About the 2022-2026 Ford E-Transit

The primary issue for the Ford E-Transit and code C1114 is the lack of public information, forcing reliance on diagnostic patterns from other Ford vehicles. Unlike General Motors, which has numerous Technical Service Bulletins (TSBs) defining C1114 as a trailer brake control fault, Ford uses this code family for other systems. The provided NHTSA complaints for GMC vehicles (ODI #11589523, #11710153) are prime examples of how this code is interpreted on a different manufacturer and are not relevant for diagnosing your E-Transit. The key is using a tool like FORScan to get the Ford-specific definition and suffix code.

Symptoms You May Notice

• ABS warning light illuminated on the dashboard
• Traction or Stability Control warning light illuminated
• "Service AdvanceTrac" message on the instrument cluster

Most Likely Causes

Rare But Worth Checking

• Low battery voltage causing multiple electronic modules to set faults
• Faulty charging system (alternator) leading to unstable voltage

Diagnosis Steps

1. STOP: Do not proceed with parts replacement based on information from other vehicle brands.
2. Connect a high-level scan tool capable of reading Ford-specific codes (e.g., FORScan). Record the full DTC, including the suffix (e.g., C1114:XX), and any other codes stored in other modules.
3. Check Fuses and Relays: Locate the engine compartment fuse box (Battery Junction Box). Inspect fuses related to the ABS system (often labeled ABS, ABS PMP, or similar). A user on a Ford Transit forum with a similar 'low voltage at ABS module' issue was advised to check fuses F8 (25A) and F25 (40A) in the engine bay fuse box, and fuse F73 (5A) in the passenger fuse box, which may be relevant starting points. Locate the ABS Power Relay and swap it with an identical relay from a non-critical system (like the horn) to see if the code changes or resolves.
4. Inspect ABS Module Connector: Locate the ABS module, typically attached to the hydraulic control unit on the driver's side of the engine bay. On some Transits, this can be difficult to access, potentially requiring removal of the battery and battery tray. Disconnect the battery. Unplug the large electrical connector from the ABS module and inspect for any signs of corrosion, moisture, or bent/damaged pins.
5. Check Power and Ground: Using a multimeter and a wiring diagram, check for battery voltage at the appropriate power pins on the ABS module's wiring harness connector (with the key on). Check for good continuity to ground on the ground pins (resistance should be less than 5 ohms). Wiggle the harness while testing to see if the voltage drops or resistance spikes, which would indicate an intermittent open or short in the wiring.
6. If the relay, fuses, and wiring are confirmed to be good, the fault may be internal to the ABS control module itself, which may require replacement and programming.

Parts You'll Likely Need

• ABS Power Relay
• ABS Module Fuse
• ABS Control Module

Related Codes That Often Appear With This One

• U3003:16 or U3003:17 (Battery Voltage - Circuit Voltage Below/Above Threshold)
• U3000:49 (Control Module - Internal Electronic Failure)

Mechanic-Grade Diagnostic Values

• ABS Module Ground Circuit Resistance — expected: Less than 5.0 ohms. Failure: Resistance greater than 5.0 ohms indicates a poor ground connection.
• ABS Module Power Supply Voltage (harness wiggle test) — expected: Stable battery voltage (above 10V). Failure: Voltage momentarily drops below 10 volts while wiggling the wiring harness, indicating an open or short.

Hidden / Shadow Codes Worth Checking

• C1114:01: General Electrical Failure. This is a generic suffix and requires checking the full circuit. (see via Ford IDS, FORScan, or other high-level diagnostic scanner.)
• C1114-08: Signal Bus/Message Failure. This points towards a communication issue on the CAN bus network rather than a simple power/ground fault. (see via Ford IDS, FORScan, or other high-level diagnostic scanner.)

Scan Tool Commands That Help

• FORScan: ABS Module Initialization (under PATS) — Required after replacing the ABS module to make the vehicle recognize the new unit. The car will set multiple codes and may not start if a used module is installed without initialization.
• FORScan: ABS As-Built Format (Configuration and Programming) — Used to write the vehicle's original configuration data (including VIN) to a new or used replacement ABS module. This is critical for ensuring all features function correctly.
• FORScan / FDAS: ABS Service Functions (e.g., 'Maintenance Mode') — Used to retract brake caliper pistons for service. Caution is advised, as improper use can lead to a state where the module will not exit maintenance mode, disabling the power brakes until reset with dealer-level software.

Wiring & Ground Locations

• 12V Battery — Under the left-hand (driver's side) front seat. Access requires moving the seat forward and removing trim panels.. The primary source of power for all 12V systems, including the ABS module. A weak battery or loose/corroded terminals here can cause low voltage codes across multiple modules.
• Battery Junction Box (BJB) / Engine Fuse Box — Located in the engine compartment, typically on the driver's side.. This box contains the main high-amperage fuses (e.g., 40A, 60A) and the power relay for the ABS module. A blown fuse or faulty relay here is a direct cause of power-related ABS codes.
• G108 — A wiring diagram indicates a ground point G108 is located on the right side of the engine compartment.. This is a potential ground point for the ABS module. A corroded or loose connection at this ground would cause high resistance and trigger power circuit or communication faults.

OEM Part Supersession History

• CK4Z-2C405-A, EK4Z-2C405-A → FK4Z-2C405-C — Part revision or update for 2015-2019 Ford Transit models.
• NK4Z-2C219-D → NK4Z-2C219-F — Part revision for 2023-2025 Ford Transit models.
• kv6z2b373b, kv6z2b373c → KV6Z-2B373-D — Part revision for Ford Transit Connect models from 2019-2023.
  Heads up: This part is for the smaller Transit Connect and is not compatible with the full-size E-Transit.

Model Year Variations Within This Range

• 2020-2024: The Ford Transit models in this range use a Bosch 9.0 ABS system, which replaced the older ceramic-based Bosch 8.0 modules. The 9.0 version uses a more conventional (but harder to service) Printed Circuit Board (PCB).

Used vs. New Parts: Buying Guide for This Vehicle

When a used part is the smart pick: A used ABS module can be a cost-effective option if the failure is confirmed to be internal to the module and not a wiring or power supply issue. However, it is critical to understand that it will require reprogramming.

Donor-vehicle mileage cap: roughly under 80000 miles for the part to have meaningful remaining life.

What to inspect on the donor part:

• Obtain the VIN of the donor vehicle to acquire its 'As-Built' data from Ford's servers, which is needed for reprogramming.
• Inspect the electrical connector pins on the used module for any signs of corrosion, damage, or moisture intrusion.
• Ensure the part number on the used module is an exact match or a known superseded number for the original part.
• Source the part from a reputable seller who guarantees it is a functional, tested unit.

OEM-only on this vehicle (don't cheap out):

• ABS Control Module: While used OEM modules are an option, aftermarket 'new' modules are generally not available or recommended. Rebuilding the original module through a specialized service is another viable path.

Aftermarket brands forum-validated for this vehicle:

• For rebuilding services: XeMODeX is a known company that services Bosch 9.0 ABS modules.

Brands owners have reported issues with on this vehicle:

• Unknown/unbranded ABS modules from online marketplaces should be avoided due to the complexity and safety-critical nature of the part, plus the necessity of programming.
