Solution

1. Preparation

Gather tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Allow the vehicle to cool down before working on the braking system.

2. Inspect and Clean ABS Wheel Speed Sensors

Sub-steps:
- Locate the ABS wheel speed sensors on each wheel hub.
- Remove any dirt or debris around the sensors using a soft brush.
- Disconnect the electrical connector from the sensor.
- Clean the sensor contact points with electrical contact cleaner.
- Reconnect the sensor and ensure it is securely mounted.

3. Check ABS Control Module Connections

Sub-steps:
- Locate the ABS control module, typically found near the master cylinder.
- Inspect all wiring and connectors for signs of corrosion or damage.
- Clean any corroded connections with a wire brush and apply dielectric grease.
- Ensure all connections are tight and properly seated.

4. Inspect and Replace Brake Fluid if Necessary

Sub-steps:
- Check the brake fluid level and condition in the reservoir.
- If the fluid is dark or contaminated, drain the old fluid using a brake bleeder kit.
- Refill with fresh brake fluid as specified by the manufacturer (DOT 3 or DOT 4).
- Bleed the brake system to remove any air from the lines.

5. Test Drive and Recheck

Sub-steps:
- Reconnect the negative battery terminal.
- Start the vehicle and perform a test drive to check for ABS light illumination.
- Monitor braking performance and ensure no pulsation or warning lights occur.
