Symptoms
- • ABS, traction control, and hill-descent lights on together
- • Hard brake pedal, then suddenly soft
- • ABS pump runs continuously with key off
- • Speedometer drops to zero or flickers
- • Scan tool can't communicate with ABS module
- • Trailer-sway / AdvanceTrac disabled
Common codes
- C1011 — pump motor circuit failure
- C1095 — ABS hydraulic pump motor
- C1145–C1148 — wheel speed sensor inputs to module
- U0121 — lost communication with ABS control module
- C1288 — steering angle sensor (HCU side)
Vehicles affected
- • 2009–2014 Ford F-150
- • 2011–2019 Ford Explorer
- • 2013–2019 Ford Escape
- • 2011–2018 Ford Edge / Lincoln MKX
- • 2010–2014 Ford Mustang
- • 2011–2019 Ford Fusion / Lincoln MKZ
Why it fails
The control module sits directly on the hydraulic pump and gets cooked by both engine-bay heat and pump-motor current. The pump-driver MOSFET shorts internally, which can leave the pump running with the key off (and kill the battery overnight). On later units, the internal CAN transceiver fails, dropping the module off the bus entirely.
How TMW Repairs fixes it
- Ship just the control unit on top — the hydraulic block stays on the truck, no brake bleeding needed.
- We replace the failed pump-driver MOSFETs, CAN transceiver, and any cracked solder around the high-current connections.
- The board is load-tested on a simulator before it ships back.
- Bolt it back on. No programming, no IDS / FORScan trip — your VIN and as-built data are still in the module.
What you get
- • 2–3 business day turnaround once received
- • 1-year warranty on the repair
- • No coding, no programming, no bleeding
- • Roughly 70% cheaper than a new HCU

Questions buyers ask before sending it in
Which Fords are affected by HCU failure?
Most commonly 2010–2019 F-150, 2011–2019 Explorer, 2013–2019 Escape, 2011–2018 Edge, and 2010–2017 Fusion. The failure pattern is identical: solenoid driver ICs inside the control unit overheat and short.
Do I have to ship the hydraulic block?
No. Only the control unit (top section) ships in — the hydraulic block stays on the vehicle, so the brake hydraulic circuit is never opened and no bleeding is required afterward.
Will the repair clear my codes?
Yes. Once the repaired control unit is reinstalled, cycling the key clears the dashboard lights and codes such as C1011, C1013, C1014, C1184, U0121, and pump-motor circuit faults.
How long is the turnaround?
24–48 hours from arrival at our Florida workshop plus return shipping (FedEx overnight available).
What's the warranty?
1-year warranty on the repaired module. If anything we touched fails, we cover the re-repair and return shipping.
