BL3Z-2C405-J | Genuine Ford ABS Anti-Lock Brake Hydraulic Module HCU Ford F-150

**Description:** An ABS Control Unit **BL3Z-2C405-J** (also called the ABS Module, ABS ECU, or ABS Controller) is the electronic “brain” of the Anti-lock Braking System in a vehicle. It monitors wheel speed and controls the brake pressure to prevent the wheels from locking during braking. **Part Number**: BL3Z-2C405-J, BL3Z2C405J **Condition**:Remanufactured **Manufacture/Brand**: Ford **Related Part Numbers:** BL3Z-2C405-H, BL3Z2C405H **Fits BL3Z-2C405-J For:** Year Make ModelEngineImportant vehicle option details2011-2012 Ford F-1506 Cyl 3.5L DOHC TIVCT, 6 Cyl 3.7L PFI NA, 8 Cyl 4.6L, 8 Cyl 5.0L MOD DOHC SEFI NA, 8 Cyl 6.2L OHC NA4-Speed Automatic Transmission 4R75E Livonia, 4-Speed Automatic Transmission AODEW/4R70E W/TSS, 4-Speed Automatic Transmission AODEW/4R75E W/TSS, 5-Speed Manual Transmission - Mazda M5R2-C, 6-Speed Automatic Transmission (6R80), Four-Wheel Drive (Part Time) (Left Hand Drive), Left Hand Drive2011-2012 Lincoln Mark LT6 Cyl 3.5L DOHC TIVCT, 6 Cyl 3.7L PFI NA, 8 Cyl 4.6L, 8 Cyl 5.0L MOD DOHC SEFI NA, 8 Cyl 6.2L OHC NA4-Speed Automatic Transmission 4R75E Livonia, 4-Speed Automatic Transmission AODEW/4R70E W/TSS, 4-Speed Automatic Transmission AODEW/4R75E W/TSS, 5-Speed Manual Transmission - Mazda M5R2-C, 6-Speed Automatic Transmission (6R80), Four-Wheel Drive (Part Time) (Left Hand Drive), Left Hand Drive **Purpose of using BL3Z-2C405-J:** **1\. Prevent wheel lock-up** - Stops the wheels from locking during hard or emergency braking. - Helps maintain traction with the road. **2\. Maintain steering control** - Allows the driver to steer while braking hard, preventing skidding or sliding. **3\. Control brake pressure automatically** - Sends commands to the ABS hydraulic unit to rapidly apply and release brake pressure (pulsing). - Optimizes braking performance on slippery or uneven surfaces. **4\. Improve stopping stability** - Keeps the vehicle stable by preventing uncontrolled sideways movement or fishtailing. **5\. Support other safety systems** - Works with Traction Control (TCS), Electronic Stability Control (ESC), and Hill Assist systems. - Helps manage wheel slip and body stability. **6\. Monitor and adjust in real time** - Uses signals from wheel speed sensors to react instantly (hundreds of times per second). **Signs of a Bad ABS Control Unit BL3Z-2C405-J**: **1\. Hard starting or no start** If the pump can’t build enough pressure, the engine will crank for a long time or fail to start. **2\. Loss of power / poor acceleration** Low fuel pressure from a worn pump causes: - Weak acceleration - Poor pulling power - Struggling on hills **3\. Rough idle or engine misfires** Uneven fuel delivery makes the engine shake, idle roughly, or misfire. **4\. Excessive smoke from the exhaust** Different smoke types can give clues: - **Black smoke:** too much fuel (over-fueling) - **White smoke:** unburnt fuel (low pressure or bad timing) - **Blue smoke:** oil burning (not always pump-related but can be connected) **5\. Sudden engine stalling** If the pump can’t keep consistent pressure, the engine may stall while driving or idling. **6\. Poor fuel economy** Bad fuel metering from the pump causes the engine to use more fuel than normal. **7\. Engine overheating** A weak pump can cause the air-fuel mixture to run lean, increasing engine temperature. **8\. Fuel leaks** A cracked or worn pump housing can leak diesel, leading to: - Smell of fuel - Visible wet spots - Low fuel pressure **9\. Unusual noises from the pump** Grinding, whining, or ticking sounds can indicate internal pump wear or failure.
