why does my Ford Explorer ABS light stay on after I start the engine

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent any electrical shorts during repair.

2. Inspect and Replace ABS Fuse

• Locate the fuse box and identify the ABS fuse (refer to the owner's manual).
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; replace if blown with a fuse of the same amperage.

3. Check and Refill Brake Fluid

• Open the hood and locate the brake master cylinder.
• Check the brake fluid level; if low, clean the reservoir cap and top up with the specified brake fluid type (DOT 3 or DOT 4).
• Inspect for any leaks in the brake lines or around the master cylinder.

4. Inspect ABS Sensors

• Lift the vehicle using a jack and secure it with jack stands.
• Remove the wheel to access the ABS sensor.
• Inspect the sensor for physical damage or dirt; clean if dirty or replace if damaged.
• Ensure the sensor wiring is properly connected and free from corrosion.

5. Test ABS Control Module

• Reconnect the battery.
• Use a multimeter to test the voltage at the ABS control module.
• If voltage is present but the light remains on, the control module may need replacement.
