Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shock.

2. Retrieve and Address Fault Codes

Use the OBD-II scanner to clear any existing ABS fault codes after noting them.
If the ABS light persists after clearing codes, proceed with inspection of the identified components.

3. Inspect Wheel Speed Sensors

Remove the wheel on which the ABS light is triggered.
Locate the wheel speed sensor; clean any dirt or debris on the sensor and connector.
Use a multimeter to test the sensor's resistance; replace if out of specification.
Reinstall the wheel and torque the lug nuts to manufacturer specifications.

4. Check and Replace Fuse (if necessary)

Access the fuse box as per the vehicle manual.
Locate the ABS fuse and check for continuity; replace with an identical fuse if blown.

5. Inspect ABS Module and Wiring

Visually inspect the ABS module for corrosion or physical damage.
Check wiring connections for secure fit; repair any damaged wires.
Reconnect the negative battery terminal.

6. Refill and Bleed Brake Fluid (if necessary)

Check brake fluid level; if low, add fluid that meets Honda specifications (usually DOT 3 or DOT 4).
If brake fluid was low, bleed the brake system to remove air; start from the furthest wheel from the master cylinder.
