⚠️ Common Symptoms of a Bad ABS Control Module:

When the ABS module suffers from internal electronic failure or solder joint cracks on your Ford F150, it will cause serious braking and electrical glitches, leading to these clear warning signs:

• ABS Light & Brake Light Staying On: The most common sign is the amber ABS warning light and the red brake light permanently illuminated on your dashboard.
• ABS Pump Motor Runs Continuously: A failing module can get stuck in a loop, causing the ABS pump to run non-stop even when the truck is turned off, completely draining your battery overnight.
• Brake Pedal Pulsation or Hardness: You might feel abnormal pulsing or a heavy, stiff brake pedal during normal, dry-weather braking conditions.
• Brakes Locking Up: Under sudden braking, the anti-lock system fails to engage, causing your tires to lock up and skid just like an older vehicle without ABS.
• Diagnostic Trouble Codes (DTCs): Your scanner fails to communicate with the braking system or triggers specific module codes like C1155, C1145, or internal relay codes.

If you are dealing with a dead battery from a humming pump or annoying dash lights, locating this electronic module is your very first step. Watch the video to see exactly where it is hidden on the truck so you can complete your inspection or replacement quickly and safely!
