22754644 | Genuine GM® Anti-Lock Brake HCU & Module Kit 2012-2017

**Description**: An Anti-Lock Brake HCU & Module Kit **22911902** is a key part of a vehicle’s ABS (Anti-Lock Braking System). It helps you keep control of the vehicle during hard or emergency braking.  ABS prevents the wheels from locking up when you brake hard.  This helps you steer while braking and reduces skidding, especially on wet or slippery roads. **Part Number**: 22754644 **Condition**: Remanufactured **Manufacture/Brand**: GM **Related Part Numbers:** 22911900, 22754644, 23130972 **Fits** **22911902** For YearMakeModelBody & TrimEngine & Transmission2017ChevroletEquinoxL, LS, LT, Premier2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2017GMCTerrainDenali, SL, SLE, SLT2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2016ChevroletEquinoxL, LS, LT, LTZ2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2016GMCTerrainDenali, SL, SLE, SLT2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Gas2015ChevroletEquinoxL, LS, LT, LTZ2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2015GMCTerrainDenali, SL, SLE, SLT2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2014ChevroletEquinoxLS, LT, LTZ2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2014GMCTerrainDenali, SLE, SLT2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2013ChevroletEquinoxLS, LT, LTZ2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2013GMCTerrainDenali, SLE, SLT2.4L L4 - Flex, 2.4L L4 - Gas, 3.6L V6 - Flex, 3.6L V6 - Gas2012ChevroletEquinoxLS, LT, LTZ2.4L L4 - Flex, 2.4L L4 - Gas, 3.0L V6 - Flex, 3.0L V6 - Gas2012GMCTerrainSLE, SLT2.4L L4 - Flex, 2.4L L4 - Gas, 3.0L V6 - Flex, 3.0L V6 - Gas **Purpose of using** **22911902:** **1\. Prevents wheel lock-up** - During sudden or hard braking, wheels can lock and skid. - The HCU rapidly adjusts brake fluid pressure to each wheel. - This keeps the tires **rolling instead of sliding**. **2\. Maintains steering control** - When wheels lock, you can’t steer. - ABS lets you **brake and steer at the same time**, helping you avoid obstacles. **3\. Improves braking on slippery surfaces** - Works especially well on: - Wet roads - Snow or ice - Gravel - Reduces skidding and loss of control. **4\. Supports safety systems** - The ABS module works with: - **Traction Control** - **Electronic Stability Control (ESC)** - These systems help prevent spinning or sliding. **5\. Restores proper brake system function** - Using the **HCU & Module Kit** replaces both the hydraulic and electronic parts together. - Ensures proper communication and reliable braking performance. **6\. Meets safety and legal requirements** - ABS is required on most modern vehicles. - A working HCU & module keeps the vehicle **road-legal and safe to drive**. **Sings of Bad Anti-Lock Brake HCU & Module Kit** **22911902:** **Warning lights & messages** - **ABS warning light** stays on - **Brake warning light** (red or amber) - **Traction Control / Stability Control light** - Messages like: - _“ABS fault”_ - _“Service brake system”_ - _“Stability control disabled”_ **Braking behavior changes** - **ABS doesn’t activate** during hard braking - Wheels **lock up and skid** on slippery roads - **Brake pedal feels hard, soft, or inconsistent** - Brake pedal **pulsation is missing** when ABS should be active **Vehicle handling issues** - **Loss of traction control** - **Loss of stability control** - Vehicle may feel unstable during emergency stops or sharp turns **Noises from ABS system** - Grinding, buzzing, or clicking noises near the ABS unit - ABS pump runs constantly or **does not run at all** **Diagnostic trouble codes** - Codes related to: - ABS pump motor - Hydraulic valves - Internal ABS module failure - Wheel speed sensor codes that **don’t clear** even after sensor replacement **Fluid or hydraulic issues** - Brake fluid leaks around the HCU - Brake pressure imbalance between wheels **Important safety note** Even if ABS fails: - **Normal braking still works**, but - You lose ABS, traction control, and stability control safety features
