In this video, I show you the exact location and the complete step-by-step process to replace the ABS (Anti-lock Braking System) Control Module on a 2006-2013 Chevrolet Impala equipped with the 3.5L V6 engine.
Knowing exactly where this electronic module sits mounted to the ABS hydraulic brake valve assembly will save you time, keep you from removing unnecessary parts, and prevent you from damaging the sensitive brake lines during this DIY repair.
Common Symptoms of a Bad ABS Control Module:
- The ABS warning light and the traction control/StabiliTrak light stay permanently illuminated on the dashboard
- An OBD-II scanner reveals specific module communication errors or circuit codes like C0035, C0040, or U0121
- The brakes lock up easily under heavy stopping conditions, losing their anti-lock pulsing functionality
- The vehicle’s speedometer behaves erratically, drops to zero, or stops functioning entirely
- Increased braking effort or an uncharacteristically stiff brake pedal response
Safety First
Always prioritize safety before starting this repair. Make sure the vehicle is safely parked on a flat, level surface, the emergency brake is securely engaged, and the ignition is turned completely off with the keys removed. Because you are working with the electrical brain of the braking system, you must disconnect the negative battery terminal before starting to prevent voltage spikes from destroying the new module. Ensure the engine and cooling system are completely cool to avoid burns. Wear safety glasses to protect your eyes from under-hood dirt or fluid, and use durable work gloves to protect your hands when maneuvering in tight spaces.
