how to troubleshoot ABS light on my Honda Pilot YF3 (2016-2022)?

Solution

1. Preparation

• Gather tools and safety gear.
• Ensure the vehicle is parked on a level surface and the ignition is off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Scan and Clear Codes

• Use an OBD-II scanner to read and document any stored ABS trouble codes.
• Clear the codes and check if the ABS light returns after a test drive.

3. Inspect Wheel Speed Sensors

• Remove the wheel corresponding to the faulty sensor.
• Locate the wheel speed sensor; it’s usually near the brake rotor.
• Disconnect the sensor's electrical connector and inspect for dirt or corrosion.
• Clean the sensor with electrical contact cleaner.
• Reconnect the sensor and confirm it is securely mounted.

4. Check ABS Control Module

• Locate the ABS control module, typically near the master cylinder.
• Inspect the connector for corrosion or loose pins.
• If necessary, clean the connector and ensure a secure fit.
• If the module is faulty, replace it following manufacturer specifications.

5. Brake Fluid Inspection

• Locate the brake fluid reservoir and check fluid level; it should be between the "MIN" and "MAX" marks.
• If fluid is low, top off with the recommended brake fluid type (usually DOT 3 or DOT 4).
• Inspect fluid for contamination; if it appears dark or murky, consider flushing the brake system.
