how to diagnose the ABS light on Honda CR-V Sixth Generation (2023-present)?

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, and torque wrench.
• Disconnect the vehicle’s battery to ensure safety while working on the electrical system.
• Allow the vehicle to cool down before working on the components.

2. Check and Replace ABS Fuse

• Locate the fuse box under the dashboard or under the hood.
• Remove the ABS fuse using a fuse puller or pliers.
• Check for continuity with a multimeter. If blown, replace it with a fuse of the same amperage.

3. Inspect and Clean ABS Wheel Speed Sensors

• Raise the vehicle using a jack and secure it with jack stands.
• Locate the ABS wheel speed sensors at each wheel hub.
• Disconnect the sensor connectors and visually inspect for dirt or damage.
• Clean the sensors with an appropriate cleaner and reconnect them.

4. Check Brake Fluid Level

• Open the hood and locate the master cylinder reservoir.
• Check the brake fluid level; it should be within the designated marks on the reservoir.
• If low, top up with the manufacturer-recommended brake fluid type.

5. Test and Replace ABS Module (if necessary)

• Use a multimeter to check the power and ground supply to the ABS module.
• If the module is not receiving power, trace the wiring back to the battery and fuse.
• If the ABS module is faulty, remove it by unscrewing the mounting bolts and disconnecting the wiring harness.
• Install a new ABS module by reversing the removal steps, ensuring all connections are secure.
